| 5 | CVE-2020-27511 | An issue was discovered in the stripTags and unescapeHTML components in Prototype 1.7.3 where an attacker can cause a Regular Expression Denial of Service (ReDOS) through stripping crafted HTML tags. | prototype 1.7.3 |
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 They are usually related to outdated systems and expose the affected applications to the risk of unauthorized access to confidential data and possibly denial of service attacks.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.

Evidence
| URL | Evidence |
|---|---|
| https://bgzisbvspkwwtkzoxlgu.shop:443/login_up.php | 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.

Vulnerability description
We noticed that the target application's server responses lack the Referrer-Policy HTTP header, which controls how much referrer information the browser will send with each request originated from the current web application.
Risk description
The risk is that if a user visits a web page (e.g. "http://example.com/pricing/") and clicks on a link from that page going to e.g. "https://www.google.com", the browser will send to Google the full originating URL in the `Referer` header, assuming the Referrer-Policy header is not set. The originating URL could be considered sensitive information and it could be used for user tracking.
Recommendation
The Referrer-Policy header should be configured on the server side to avoid user tracking and inadvertent information leakage. The value `no-referrer` of this header instructs the browser to omit the Referer header entirely.

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).

Vulnerability description
We noticed that server software and technology details are exposed, potentially aiding attackers in tailoring specific exploits against identified systems and versions.
Risk description
The risk is that an attacker could use this information to mount specific attacks against the identified software type and version.
Recommendation
We recommend you to eliminate the information which permits the identification of software platform, technology, server and operating system: HTTP server headers, HTML meta information, etc.
Evidence
| URL | Evidence |
|---|---|
| https://bgzisbvspkwwtkzoxlgu.shop:443/login_up.php | 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.

Vulnerability description
We noticed that this web application exposes email addresses, which might be unintended. While not inherently a vulnerability, this information could be leveraged in social engineering or spam related activities.
Risk description
The risk is that exposed email addresses within the application could be accessed by unauthorized parties. This could lead to privacy violations, spam, phishing attacks, or other forms of misuse.
Recommendation
Compartmentalize the application to have 'safe' areas where trust boundaries can be unambiguously drawn. Do not allow email addresses to go outside of the trust boundary, and always be careful when interfacing with a compartment outside of the safe area.

Vulnerability description
We have noticed that the server is missing the security.txt file, which is considered a good practice for web security. It provides a standardized way for security researchers and the public to report security vulnerabilities or concerns by outlining the preferred method of contact and reporting procedures.
Risk description
There is no particular risk in not having a security.txt file for your server. However, this file is important because it offers a designated channel for reporting vulnerabilities and security issues.
Recommendation
We recommend you to implement the security.txt file according to the standard, in order to allow researchers or users report any security issues they find, improving the defensive mechanisms of your server.

Infrastructure Vulnerabilities
Evidence
We managed to detect a publicly accessible SSH service. Starting Nmap ( https://nmap.org ) at 2025-07-18 22:45 EEST Nmap scan report for bgzisbvspkwwtkzoxlgu.shop (84.200.192.180) Host is up (0.015s latency).
PORT STATE SERVICE VERSION 22/tcp open ssh OpenSSH 8.9p1 Ubuntu 3ubuntu0.13 (Ubuntu Linux; protocol 2.0) | ssh-auth-methods: | Supported authentication methods: | publickey |_ password Service Info: OS: Linux; CPE: cpe:/o:linux:linux_kernel
Service detection performed. Please report any incorrect results at https://nmap.org/submit/ . Nmap done: 1 IP address (1 host up) scanned in 0.82 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 managed to detect a publicly accessible Post Office Protocol (POP3) service. Starting Nmap ( https://nmap.org ) at 2025-07-18 22:45 EEST Nmap scan report for bgzisbvspkwwtkzoxlgu.shop (84.200.192.180) Host is up (0.015s latency).

Service detection performed. Please report any incorrect results at https://nmap.org/submit/ . Nmap done: 1 IP address (1 host up) scanned in 6.60 seconds
Vulnerability description
We found that the Post Office Protocol (POP3) service is publicly accessible and doesn’t include STARTTLS capability. Email clients use the Post Office Protocol (POP) to download emails for user accounts. Some POP servers are initially set up to operate over an unsecured protocol. When email clients download email content through this plaintext protocol, it can pose a substantial risk to the organization's network, especially depending on which user account is set to receive the emails.
Risk description
Exposing this service online can enable attackers to conduct man-in-the-middle attacks, thereby gaining access to sensitive user credentials and the contents of emails. Given that POP3 operates via a plaintext protocol, the entirety of the data exchanged between the client and server is left unencrypted. This critical information could then be leveraged in further attacks on the organization's network.
Recommendation
We recommend turning off POP3 access over the Internet and instead using a Virtual Private Network (VPN) that mandates two-factor authentication (2FA). If the POP3 service is essential for business purposes, we recommend limiting access only from designated IP addresses using a firewall. Furthermore, activating STARTTLS capability (switching the connection to a secure communication) or utilizing Secure POP3 (POP3S) is recommended, as this protocol employs encryption.
Evidence
We managed to detect a publicly accessible File Transfer Protocol (FTP) service. PORT STATE SERVICE VERSION 21/tcp open ftp ProFTPD
Vulnerability description
We found that the File Transfer Protocol (FTP) service is publicly accessible. The FTP enables client systems to connect to upload and download files. Nonetheless, FTP lacks encryption for the data exchanged between the server and the client, leaving all transferred data exposed in plaintext.
Risk description
Exposing this service online can enable attackers to execute man-in-the-middle attacks, capturing sensitive user credentials and the contents of files because FTP operates without encryption. The entirety of the communication between the client and the server remains unsecured in plaintext. This acquired information could further facilitate additional attacks within the network.
Recommendation
We recommend turning off FTP access over the Internet and instead using a Virtual Private Network (VPN) that mandates two-factor authentication (2FA). If the FTP service is essential for business purposes, we recommend limiting access only from designated IP addresses using a firewall. Furthermore, utilizing SFTP (Secure File Transfer Protocol) is recommended as this protocol employs encryption to secure data transfers.
Evidence
We found insecure DNS cookie usage on the following nameservers: ns1.dns-parking.com, ns2.dns-parking.com
Vulnerability description
We found that the server does not implement DNS Cookies or uses them insecurely. DNS Cookies help prevent DNS-based attacks, such as spoofing and amplification attacks.
Risk description
The risk exists because without DNS Cookies, the server is vulnerable to DNS spoofing and amplification attacks. Attackers can manipulate responses or use the server in distributed denial-of-service (DDoS) attacks, compromising network availability and security.
Recommendation
We recommend enabling DNS Cookies to prevent spoofed DNS responses. Ensure proper cookie validation is implemented to mitigate DNS amplification attacks. Regularly update DNS servers to support the latest DNS security features.

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.
