CVE-2024-54399 identifies a Cross-Site Request Forgery (CSRF) vulnerability in the CRUDLab Google Plus Button plugin, versions up to and including 1.0.2. This vulnerability allows an attacker to trick authenticated users into executing unwanted actions without their consent by leveraging the user's active session. The plugin's failure to implement proper CSRF protections enables attackers to craft malicious requests that the server accepts as legitimate. Furthermore, the vulnerability facilitates Stored Cross-Site Scripting (XSS), where malicious scripts injected by an attacker are permanently stored on the target server and executed in the context of other users' browsers. This combination of CSRF and Stored XSS can lead to session hijacking, data theft, or defacement of web content. The vulnerability affects web applications using the CRUDLab Google Plus Button, a component designed to integrate Google Plus social sharing features. Although Google Plus has been deprecated, the plugin may still be in use in legacy or niche applications. No patches or fixes have been officially released yet, and no known exploits have been detected in the wild. The vulnerability was published on December 16, 2024, with no CVSS score assigned, indicating it is a recently disclosed issue requiring immediate attention from affected parties.

The impact of CVE-2024-54399 is significant for organizations using the CRUDLab Google Plus Button plugin. Exploitation can lead to unauthorized actions performed on behalf of legitimate users, potentially compromising user accounts and application integrity. The Stored XSS component allows attackers to inject persistent malicious scripts, which can steal sensitive information such as session cookies, credentials, or perform actions within the victim's browser context. This can result in data breaches, unauthorized access, defacement, or further malware distribution. The vulnerability undermines user trust and can lead to reputational damage and regulatory consequences if sensitive data is exposed. Since the plugin is web-facing, the attack surface is broad, and exploitation requires only that a user visit a maliciously crafted webpage. This ease of exploitation combined with the potential for persistent XSS elevates the threat level. Organizations relying on this plugin, especially those with high user interaction or sensitive data, face increased risk of compromise and should act promptly to mitigate the threat.

To mitigate CVE-2024-54399, organizations should first check for any official patches or updates from the CRUDLab project and apply them immediately once available. In the absence of patches, administrators should consider disabling or removing the CRUDLab Google Plus Button plugin to eliminate the attack vector. Implementing Web Application Firewall (WAF) rules to detect and block CSRF attempts and malicious payloads can provide interim protection. Additionally, enforcing strict Content Security Policy (CSP) headers can help mitigate the impact of Stored XSS by restricting script execution sources. Developers should review and enhance CSRF protections by implementing anti-CSRF tokens and validating the origin of requests. Regular security audits and code reviews of third-party plugins are recommended to identify similar vulnerabilities proactively. User education on avoiding suspicious links can reduce the risk of exploitation. Monitoring web application logs for unusual activity related to the plugin can help detect attempted attacks early.
