Vulnerability description

Risk description

The risk is that an attacker who manages to intercept the communication at the network level can read and modify the data transmitted (including passwords, secret tokens, credit card information and other sensitive data).

Recommendation

We recommend you to reconfigure the web server to use HTTPS - which encrypts the communication between the web browser and the server.

Vulnerability description

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.

Vulnerability description

Risk description

The risk is that lack of this header could make possible attacks such as Cross-Site Scripting or phishing in Internet Explorer browsers.

Recommendation

We recommend setting the X-Content-Type-Options header such as `X-Content-Type-Options: nosniff`.

Vulnerability description

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

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.

Vulnerability description

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.

Vulnerability description

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.

Vulnerability description

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.

Vulnerability description

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.

Vulnerability description

Risk description

Without a DMARC policy, your domain is highly vulnerable to email spoofing, allowing attackers to impersonate your brand and send fraudulent emails that appear legitimate. This can lead to phishing attacks targeting your customers, employees, or partners, potentially resulting in stolen credentials, financial loss, or unauthorized access to sensitive systems. Additionally, repeated spoofing attempts can severely damage your brand's reputation, as recipients may lose trust in communications from your domain, associating your brand with malicious activity. The absence of DMARC also prevents you from monitoring and mitigating email-based attacks, leaving your domain exposed to ongoing abuse.

Recommendation

We recommend implementing a DMARC policy for your domain. Start by configuring a DMARC record with a policy of p=none, which will allow you to monitor email flows without impacting legitimate emails. This initial setup helps identify how emails from your domain are being processed by recipient servers. Once you’ve verified that legitimate emails are passing SPF and DKIM checks, you can gradually enforce stricter policies like p=quarantine or p=reject to protect against spoofing and phishing attacks. Additionally, include rua and ruf email addresses in the DMARC record to receive aggregate and forensic reports. These reports will provide valuable insights into authentication failures and help you detect any spoofing attempts.

Vulnerability description

Risk description

Using a common DKIM selector makes it easier for attackers to predict and exploit email authentication weaknesses. Attackers may attempt to find corresponding DKIM keys or improperly managed records associated with common selectors. If a common selector is coupled with a weak key length or poor key management practices, it significantly increases the likelihood of email spoofing and phishing attacks.

Recommendation

We recommend using unique, customized selectors for each DKIM key to make it more difficult for attackers to predict and target the domain's DKIM records. Regularly rotate selectors and associated keys to further strengthen the security of your domain's email authentication infrastructure.

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.
