CVE-2025-24019 is a high-severity vulnerability affecting YesWiki, a PHP-based wiki system, present in versions up to and including 4.4.5. This vulnerability allows any authenticated user to delete any file owned by the user running the FastCGI Process Manager (FPM) on the host without restrictions on the filesystem's scope. The implications of this vulnerability are severe, as it can lead to partial data loss and significant defacement or deterioration of the website.
Exploiting this vulnerability does not require high privileges or user interaction, making it accessible to a wide range of attackers. In a standard installation, the FPM process may be owned by the same user as critical PHP files. Thus, a malicious authenticated user could potentially delete essential files such as index.php, effectively cutting off access to the wiki entirely.
This vulnerability has been assigned a CVSS score of 7.1, indicating a high level of severity. Organizations utilizing YesWiki should prioritize patching to version 4.5.0, which addresses this issue, to prevent potential exploitation.
Organizations should prioritize patching immediately. The risk to organizations includes unauthorized file deletion and potential loss of data integrity.
Security teams should also consider implementing additional access controls and monitoring mechanisms to detect any unauthorized activities related to file management in YesWiki.
For further context on vulnerabilities and their management, organizations can explore resources on vulnerability management programs and penetration testing methodologies.
This vulnerability is classified under CWE-22, indicating improper limitation of a pathname to a restricted directory. Understanding the underlying causes of such vulnerabilities is essential for effective remediation and prevention.
It's crucial for security teams to remain vigilant and proactive in addressing known vulnerabilities. Regular updates and audits of the systems can significantly mitigate the risks associated with such vulnerabilities.
