CVE-2024-22491: n/a in n/a
A Stored Cross Site Scripting (XSS) vulnerability in beetl-bbs 2.0 allows attackers to run arbitrary code via the post/save content parameter.
AI Analysis
Technical Summary
CVE-2024-22491 is a Stored Cross Site Scripting (XSS) vulnerability identified in beetl-bbs version 2.0. This vulnerability arises from improper sanitization or validation of user-supplied input in the 'post/save' content parameter, allowing an attacker to inject malicious scripts that are stored on the server and executed in the context of other users' browsers when they view the affected content. The vulnerability is classified under CWE-79, which pertains to improper neutralization of input during web page generation. The CVSS v3.1 base score is 5.4, indicating a medium severity level. The vector string (CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N) shows that the attack can be performed remotely over the network (AV:N) with low attack complexity (AC:L), requires privileges (PR:L) and user interaction (UI:R), and impacts confidentiality and integrity to a limited extent (C:L/I:L) but does not affect availability (A:N). The scope is changed (S:C), meaning the vulnerability affects resources beyond the security scope of the vulnerable component. No patches or known exploits in the wild have been reported as of the publication date (January 16, 2024).
Potential Impact
For European organizations using beetl-bbs 2.0, this vulnerability could lead to unauthorized script execution within users' browsers, potentially resulting in session hijacking, credential theft, or unauthorized actions performed on behalf of legitimate users. Since the vulnerability requires some level of privilege (PR:L) and user interaction (UI:R), the risk is somewhat mitigated but still significant, especially in environments where users have elevated privileges or where social engineering can be leveraged. The confidentiality and integrity of user data could be compromised, leading to data breaches or manipulation of forum content. Given the scope change, attackers might leverage this vulnerability to affect other components or users beyond the initially targeted context. This can undermine trust in community platforms, disrupt communication, and potentially expose sensitive organizational information if the forum is used for internal discussions or customer interactions.
Mitigation Recommendations
Organizations should immediately audit their use of beetl-bbs 2.0 and assess exposure to the 'post/save' content parameter. Since no official patch is currently available, mitigation should focus on implementing strict input validation and output encoding on all user-supplied content, particularly in the post submission workflows. Employ Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts in browsers. Additionally, limit user privileges to the minimum necessary to reduce the impact of exploitation. Monitoring and logging of forum activities can help detect suspicious behavior indicative of exploitation attempts. If feasible, consider temporarily disabling or restricting the vulnerable functionality until a patch or update is released. Engage with the beetl-bbs community or vendor to obtain updates or security advisories. Finally, educate users about the risks of interacting with untrusted content and encourage cautious behavior regarding links or scripts in forum posts.
