CVE-2024-54435 identifies a Cross-Site Request Forgery (CSRF) vulnerability in the Onlywire Multi Autosubmitter plugin by Thomas Hoefter, affecting all versions up to 1.2.4. The vulnerability enables attackers to trick authenticated users into submitting unauthorized requests to the vulnerable web application. This can lead to Stored Cross-Site Scripting (XSS), where malicious scripts are permanently stored on the server and executed in the context of users' browsers. The combination of CSRF and stored XSS increases the attack surface, allowing attackers to hijack user sessions, steal sensitive information, or perform actions with the victim's privileges. The vulnerability arises due to insufficient validation of requests and lack of anti-CSRF tokens in the plugin's code. No CVSS score has been assigned yet, and no public exploits have been reported, but the vulnerability is publicly disclosed and should be considered serious. The plugin is typically used for automating content submission across multiple platforms, making it a target for attackers aiming to manipulate content or user accounts on affected sites.

The impact of CVE-2024-54435 is significant for organizations using the Onlywire Multi Autosubmitter plugin. Successful exploitation can lead to unauthorized actions performed in the context of authenticated users, including content manipulation, account takeover, or injection of malicious scripts via stored XSS. This can compromise the confidentiality and integrity of user data and potentially disrupt availability if malicious scripts cause denial-of-service conditions. Attackers could leverage stored XSS to escalate privileges, spread malware, or conduct phishing attacks targeting users of the affected sites. The risk extends to any web application integrating this plugin, particularly those with high-value user accounts or sensitive data. Organizations relying on this plugin for automated content distribution may face reputational damage and operational disruption if exploited.

To mitigate CVE-2024-54435, organizations should first check for and apply any available patches or updates from the vendor once released. In the absence of patches, implement strict anti-CSRF protections by adding unique, unpredictable CSRF tokens to all state-changing requests within the plugin. Validate and sanitize all user inputs rigorously to prevent stored XSS payloads from being saved and executed. Employ Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts. Monitor web server and application logs for unusual request patterns indicative of CSRF or XSS attempts. Limit the plugin's permissions and scope to reduce potential damage. Additionally, educate users about the risks of clicking on suspicious links while authenticated. Consider disabling or replacing the plugin if immediate remediation is not feasible.
