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
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).
Evidence
| URL | Evidence |
|---|---|
| https://clear.web.cvsum.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.
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.

|---|---|
| https://clear.web.cvsum.com/ | Response headers do not include the Referrer-Policy HTTP security header as well as the |
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
| URL | Evidence |
|---|---|
| https://clear.web.cvsum.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 X-Content-Type-Options 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.
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`.

Infrastructure Vulnerabilities
Evidence
We managed to detect a publicly accessible Remote Desktop Protocol (RDP) service. PORT STATE SERVICE VERSION 3389/tcp open ms-wbt-server xrdp
Vulnerability description
We found that the Remote Desktop Protocol (RDP) service is publicly accessible. Attackers often look for the Remote Desktop Protocol service due to its capability to provide remote access and control of a server, usually one that operates on the Microsoft Windows operating system.
Risk description
Exposing this service online can enable attackers to launch authentication attacks, like guessing login credentials, potentially gaining unauthorized access. Attackers might use publicly available employee information for brute-force attacks. Vulnerabilities, such as unpatched software or protocol flaws, could also be exploited. An example is CVE-2019-0708 (Bluekeep) vulnerability. Additionally, integration with Active Directory Domain Services could allow attackers to move laterally across the network, accessing more systems and sensitive data.
Recommendation
We recommend turning off Remote Desktop Protocol access over the Internet and instead using a Virtual Private Network (VPN) that mandates two-factor authentication (2FA). Avoid permitting direct user authentication to Active Directory over the Internet to prevent attackers from engaging in password guessing or causing the lockout of legitimate domain user accounts. If the Remote Desktop Protocol service is essential for business purposes, limiting access to designated IP addresses is recommended.

|---|---|---|---|
| clear.web.cvsum.com | A | IPv4 address | 193.169.239.24 |
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.
