---|---|---|---|---|
7.8 | CVE-2019-9513 | Some HTTP/2 implementations are vulnerable to resource loops, potentially leading to a denial of service. The attacker creates multiple request streams and continually shuffles the priority of the streams in a way that causes substantial churn to the priority tree. This can consume excess CPU. | nginx 1.14.0 | |
7.8 | CVE-2019-9511 | Some HTTP/2 implementations are vulnerable to window size manipulation and stream prioritization manipulation, potentially leading to a denial of service. The attacker requests a large amount of data from a specified resource over multiple streams. They manipulate window size and stream priority to force the server to queue the data in 1-byte chunks. Depending on how efficiently this data is queued, this can consume excess CPU, memory, or both. | nginx 1.14.0 | |
7.8 | CVE-2018-16844 | nginx before versions 1.15.6 and 1.14.1 has a vulnerability in the implementation of HTTP/2 that can allow for excessive CPU usage.

If an unsanitized source object contained an enumerable __proto__ property, it could extend the native Object.prototype. | jquery 3.3.1 |
Vulnerability description
We noticed known vulnerabilities in the target application based on the server responses. They are usually related to outdated systems and expose the affected applications to the risk of unauthorized access to confidential data and possibly denial of service attacks. Depending on the system distribution the affected software can be patched but displays the same version, requiring manual checking.
Risk description
The risk is that an attacker could search for an appropriate exploit (or create one himself) for any of these vulnerabilities and use it to attack the system. Since the vulnerabilities were discovered using only version-based testing, the risk level for this finding will not exceed 'high' severity. Critical risks will be assigned to vulnerabilities identified through accurate active testing methods.
Recommendation
In order to eliminate the risk of these vulnerabilities, we recommend you check the installed software version and upgrade to the latest version.

https://optimahotels.com.ua/uk/ | Response does not include the HTTP Content-Security-Policy security header or meta tag |
Vulnerability description
We noticed that the target application lacks the Content-Security-Policy (CSP) header in its HTTP responses. The CSP header is a security measure that instructs web browsers to enforce specific security rules, effectively preventing the exploitation of Cross-Site Scripting (XSS) vulnerabilities.
Risk description
The risk is that if the target application is vulnerable to XSS, lack of this header makes it easily exploitable by attackers.
Recommendation
Configure the Content-Security-Header to be sent with each HTTP response in order to apply the specific policies needed by the application.

Evidence
Vulnerability description
We found the robots.txt on the target server. This file instructs web crawlers what URLs and endpoints of the web application they can visit and crawl. Website administrators often misuse this file while attempting to hide some web pages from the users.
Risk description
There is no particular security risk in having a robots.txt file. However, it's important to note that adding endpoints in it should not be considered a security measure, as this file can be directly accessed and read by anyone.
Recommendation
We recommend you to manually review the entries from robots.txt and remove the ones which lead to sensitive locations in the website (ex. administration panels, configuration files, etc).

https://optimahotels.com.ua/uk/ | Response headers do not include the HTTP Strict-Transport-Security header |
Vulnerability description
We noticed that the target application lacks the HTTP Strict-Transport-Security header in its responses. This security header is crucial as it instructs browsers to only establish secure (HTTPS) connections with the web server and reject any HTTP connections.
Risk description
The risk is that lack of this header permits an attacker to force a victim user to initiate a clear-text HTTP connection to the server, thus opening the possibility to eavesdrop on the network traffic and extract sensitive information (e.g. session cookies).
Recommendation
The Strict-Transport-Security HTTP header should be sent with each HTTPS response. The syntax is as follows: `Strict-Transport-Security: max-age=<seconds>[; includeSubDomains]` The parameter `max-age` gives the time frame for requirement of HTTPS in seconds and should be chosen quite high, e.g. several months. A value below 7776000 is considered as too low by this scanner check. The flag `includeSubDomains` defines that the policy applies also for sub domains of the sender of the response.

Service detection performed. Please report any incorrect results at https://nmap.org/submit/ . Nmap done: 1 IP address (1 host up) scanned in 0.95 seconds
Vulnerability description
We found that the SSH service with username/password authentication is publicly accessible. Network administrators often use remote administration protocols to control devices like switches, routers, and other essential systems. However, allowing these services to be accessible via the Internet can increase security risks, creating potential opportunities for attacks on the organization.
Risk description
Exposing this service online with username/password authentication can enable attackers to launch authentication attacks, like guessing login credentials, and potentially gaining unauthorized access. Vulnerabilities, such as unpatched software, protocol flaws, or backdoors could also be exploited. An example is the CVE-2024-3094 (XZ Utils Backdoor) vulnerability.
Recommendation
We recommend turning off SSH with username/password authentication access over the Internet and instead using a Virtual Private Network (VPN) that mandates two-factor authentication (2FA). If the SSH service is essential for business purposes, we recommend limiting access only from designated IP addresses using a firewall. Furthermore, it is advisable to utilize SSH Public Key Authentication since it employs a key pair to verify the identity of a user or process.
Evidence
We checked 2056 selectors but found no DKIM records.
Vulnerability description
We found that no DKIM record was configured. When a DKIM (DomainKeys Identified Mail) record is not present for a domain, it means that outgoing emails from that domain are not cryptographically signed. DKIM is a critical component of email authentication, allowing recipients to verify that an email was genuinely sent from an authorized server and that the message has not been altered in transit. The absence of a DKIM record leaves the domain vulnerable to email spoofing and phishing attacks, as attackers can send fraudulent emails that appear to originate from the domain without any cryptographic verification.
Risk description
Without a DKIM record, recipients have no way of verifying the integrity or authenticity of emails sent from the domain. This increases the likelihood of phishing and spoofing attacks, where malicious actors impersonate the domain to send fraudulent emails. This can lead to significant security incidents, such as credential theft, financial fraud, or the distribution of malware. Additionally, many email providers use DKIM as part of their spam and reputation filters, meaning that emails from a domain without DKIM may be flagged as spam or rejected, impacting the deliverability and reputation of legitimate emails.
Recommendation
We recommend implementing DKIM for your domain to enhance email security and protect your brand from email-based attacks. Generate a DKIM key pair (public and private keys), publish the public key in the DNS under the appropriate selector, and configure your email servers to sign outgoing messages using the private key. Ensure that the DKIM key length is at least 1024 bits to prevent cryptographic attacks. Regularly monitor DKIM signatures to ensure the system is functioning correctly and update keys periodically to maintain security.
Evidence
Domain Queried | DNS Record Type | Description | Value |
---|---|---|---|
_dmarc.optimahotels.com.ua | TXT | Text record | "v=DMARC1; p=none; sp=none" |
Vulnerability description
We found that the DMARC record for the domain is configured with sp=none, meaning that no policy is enforced for subdomains. This allows subdomains to send emails without being subject to DMARC checks, making it easier for attackers to spoof emails from these subdomains. Subdomains are often overlooked in email security, and attackers can exploit this misconfiguration to launch phishing or spoofing attacks from seemingly legitimate subdomains of a protected domain.
Risk description
When the DMARC record is configured with sp=none, subdomains are not subject to DMARC enforcement, allowing attackers to spoof emails from subdomains without being blocked. This creates a significant risk of phishing and impersonation attacks, where malicious emails appear to originate from trusted subdomains. These spoofed emails can be used to deceive users or damage the organization's reputation, undermining the security benefits of DMARC for the primary domain.
Recommendation
To mitigate the risk, we recommend that the subdomain policy should be updated to sp=reject to ensure that any email failing DMARC checks from subdomains is automatically rejected. This will help prevent unauthorized emails from being sent from subdomains, reducing the risk of spoofing and phishing. Additionally, it's important to regularly monitor DMARC reports to track email activity from subdomains and adjust policies as needed to maintain consistent security across the entire domain.
Evidence
Domain Queried | DNS Record Type | Description | Value |

optimahotels.com.ua | SPF | Sender Policy Framework | "v=spf1 ip4:95.211.150.187 ip4:95.67.11.45 include:spf2.esputnik.com ~all" |
Vulnerability description
We found that the Sender Policy Framework (SPF) record for the domain is configured with ~all (soft fail), which indicates that emails from unauthorized IP addresses are not explicitly denied. Instead, the recipient mail server is instructed to treat these messages with suspicion but may still accept them. This configuration may not provide enough protection against email spoofing and unauthorized email delivery, leaving the domain more vulnerable to impersonation attempts.
Risk description
The ~all directive in an SPF record allows unauthorized emails to pass through some email servers, even though they fail SPF verification. While such emails may be marked as suspicious or placed into a spam folder, not all mail servers handle soft fail conditions consistently. This creates a risk that malicious actors can spoof the domain to send phishing emails or other fraudulent communications, potentially causing damage to the organization's reputation and leading to successful social engineering attacks.
Recommendation
We recommend changing the SPF record's ~all (soft fail) directive to -all (hard fail). The -all setting tells recipient mail servers to reject emails from any IP addresses not listed in the SPF record, providing stronger protection against email spoofing. Ensure that all legitimate IP addresses and services that send emails on behalf of your domain are properly included in the SPF record before implementing this change.
Evidence
Domain Queried | DNS Record Type | Description | Value |
---|---|---|---|
_dmarc.optimahotels.com.ua | TXT | Text record | "v=DMARC1; p=none; sp=none" |
Vulnerability description
We found that the target uses p=none in the DMARC policy. The DMARC policy set to p=none means that the domain owner is not taking any action on emails that fail DMARC validation. This configuration effectively disables enforcement, allowing potentially spoofed or fraudulent emails to be delivered without any additional scrutiny.
Risk description
Emails that fail DMARC checks are still delivered to recipients. This leaves the domain highly vulnerable to email spoofing and phishing attacks, as malicious actors can impersonate the domain without facing any consequences from DMARC enforcement.
Recommendation
We recommend changing the DMARC policy to p=quarantine or, ideally, p=reject to actively block or quarantine emails that fail DMARC validation. This will enhance the security of your domain against spoofing and phishing attacks by ensuring that only legitimate emails are delivered.
Evidence
Domain Queried | DNS Record Type | Description | Value |
---|---|---|---|
_dmarc.optimahotels.com.ua | TXT | Text record | "v=DMARC1; p=none; sp=none" |
Vulnerability description
We found that the DMARC record for the domain is not configured with rua tag. When a DMARC record is not configured with the rua (Reporting URI for Aggregate Reports) tag, the domain owner misses out on critical feedback regarding the domain's email authentication performance. Aggregate reports are essential for monitoring how a domain's DMARC policy is applied across various mail servers and whether legitimate or malicious emails are being sent on behalf of the domain. Without this reporting, domain administrators have no visibility into how their DMARC policy is being enforced, which hinders their ability to detect potential spoofing or authentication issues.
Risk description
The absence of rua reporting creates a significant blind spot in the domain's email security posture. Without aggregate reports, domain administrators cannot track DMARC compliance across email sent from their domain, leaving them unaware of potential misconfigurations or unauthorized use of their domain for malicious purposes, such as phishing or spoofing. This lack of visibility increases the risk of undetected spoofing attempts, which could damage the domain's reputation and lead to financial, operational, or reputational harm. Moreover, legitimate email issues, such as misaligned SPF or DKIM configurations, may also go unnoticed, affecting email deliverability.
Recommendation
We recommend configuring the rua tag in the DMARC record to receive aggregate reports from mail servers. This tag should point to a reliable email address or monitoring service capable of handling DMARC aggregate reports, such as rua=mailto:dmarc-reports@example.com. These reports provide valuable insights into how email from the domain is being treated by receiving mail servers, highlighting potential authentication issues and attempts to spoof the domain. Regularly reviewing these reports will help ensure the DMARC policy is properly enforced and that any email authentication failures are addressed in a timely manner.
Evidence
Domain Queried | DNS Record Type | Description | Value |
---|---|---|---|
_dmarc.optimahotels.com.ua | TXT | Text record | "v=DMARC1; p=none; sp=none" |
Vulnerability description
We found that the DMARC record for the domain is not configured with ruf tag. A missing ruf (forensic reporting) tag in a DMARC record indicates that the domain owner has not enabled the collection of detailed failure reports. Forensic reports provide valuable insights into specific instances where emails fail DMARC authentication. Without the ruf tag, the domain administrator loses the ability to receive and analyze these reports, making it difficult to investigate individual email failures or identify targeted phishing or spoofing attacks that may be exploiting weaknesses in the email authentication setup.
Risk description
Without forensic reports (ruf), domain owners have limited visibility into the specifics of failed DMARC validation. This means potential malicious activity, such as email spoofing or phishing attempts, might go unnoticed until they result in more significant security breaches or reputational damage. Forensic reports allow for quick response to email abuses by providing detailed information about the failure, including the header information of the emails involved. The absence of this data hampers an organization's ability to identify and mitigate threats targeting its domain, increasing the risk of ongoing spoofing and fraud.
Recommendation
We recommend configuring the ruf tag in the DMARC record. This tag specifies where forensic reports should be sent, providing the domain owner with detailed data on DMARC validation failures. Forensic reports allow administrators to analyze why certain emails failed authentication, making it easier to fine-tune DMARC policies or address potential vulnerabilities. Ensure that the ruf email address belongs to a secure and trusted location capable of handling sensitive email data.
Evidence
We managed to detect that Nginx has reached the End-of-Life (EOL).
Version detected: 1.14.0 End-of-life date: 2019-04-23 Latest version for the cycle: 1.14.2 This release cycle (1.14) doesn't have long-term-support (LTS). The cycle was released on 2018-04-17 and its latest release date was 2018-12-04.
Risk description
Using end-of-life (EOL) software poses significant security risks for organizations. EOL software no longer receives updates, including critical security patches. This creates a vulnerability landscape where known and potentially new security flaws remain unaddressed, making the software an attractive target for malicious actors. Attackers can exploit these vulnerabilities to gain unauthorized access, disrupt services, or steal sensitive data. Moreover, without updates, compatibility issues arise with newer technologies, leading to operational inefficiencies and increased potential for system failures. Additionally, regulatory and compliance risks accompany the use of EOL software. Many industries have strict data protection regulations that require up-to-date software to ensure the highest security standards. Non-compliance can result in hefty fines and legal consequences. Organizations also risk damaging their reputation if a breach occurs due to outdated software, eroding customer trust and potentially leading to a loss of business. Therefore, continuing to use EOL software undermines both security posture and business integrity, necessitating timely upgrades and proactive risk management strategies.
Recommendation
To mitigate the risks associated with end-of-life (EOL) software, it's crucial to take proactive steps. Start by identifying any EOL software currently in use within your organization. Once identified, prioritize upgrading or replacing these applications with supported versions that receive regular updates and security patches. This not only helps close security gaps but also ensures better compatibility with newer technologies, enhancing overall system efficiency and reliability.Additionally, develop a comprehensive software lifecycle management plan. This plan should include regular audits to identify upcoming EOL dates and a schedule for timely updates or replacements. Train your IT staff and users about the importance of keeping software up to date and the risks associated with using outdated versions. By maintaining a proactive approach to software management, you can significantly reduce security risks, ensure compliance with industry regulations, and protect your organization's reputation and customer trust.

Risk description
An initial step for an attacker aiming to learn about an organization involves conducting searches on its domain names to uncover DNS records associated with the organization. This strategy aims to amass comprehensive insights into the target domain, enabling the attacker to outline the organization's external digital landscape. This gathered intelligence may subsequently serve as a foundation for launching attacks, including those based on social engineering techniques. DNS records pointing to services or servers that are no longer in use can provide an attacker with an easy entry point into the network.
Recommendation
We recommend reviewing all DNS records associated with the domain and identifying and removing unused or obsolete records.
