Web Application Vulnerabilities
Evidence
Vulnerability description
We found that the target application's web server presents an SSL/TLS certificate that is not trusted by web browsers. This issue typically arises when the server uses a self-signed certificate, a certificate from an untrusted authority, or a certificate that has expired or is invalid for other reasons. The lack of a trusted certificate makes it challenging for users to verify the authenticity of the server, undermining the security of the SSL/TLS connection.
Recommendation
We recommend you to configure a trusted SSL certificate for the web server. Examples of how to configure SSL for various servers for Apache and Nginx are referenced.

https://mail.brigadaindustrial.com/ | Response headers do not include the X-Content-Type-Options HTTP security header |
Vulnerability description
We noticed that the target application's server responses lack the <code>X-Content-Type-Options</code> header. This header is particularly important for preventing Internet Explorer from reinterpreting the content of a web page (MIME-sniffing) and thus overriding the value of the Content-Type header.
Recommendation
We recommend setting the X-Content-Type-Options header such as `X-Content-Type-Options: nosniff`.

https://mail.brigadaindustrial.com/ | 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.
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.

https://mail.brigadaindustrial.com/ | 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.
Recommendation
Configure the Content-Security-Header to be sent with each HTTP response in order to apply the specific policies needed by the application.

https://mail.brigadaindustrial.com/ | Response headers do not include the Referrer-Policy HTTP security header as well as the <meta> tag with name 'referrer' is not present in the response. |
Vulnerability description
We noticed that the target application's server responses lack the <code>Referrer-Policy</code> HTTP header, which controls how much referrer information the browser will send with each request originated from the current web application.
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
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.
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.

5.3 | CVE-2023-51766 | Exim before 4.97.1 allows SMTP smuggling in certain PIPELINING/CHUNKING configurations. Remote attackers can use a published exploitation technique to inject e-mail messages with a spoofed MAIL FROM address, allowing bypass of an SPF protection mechanism. This occurs because Exim supports <LF>.<CR><LF> but some other popular e-mail servers do not. | N/A |

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.
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.
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.
