CVE-2024-11615 is a medium-severity vulnerability affecting the Envolve Plugin developed by ThemeKalia for WordPress. The vulnerability arises from improper validation of file paths in the plugin's 'zetra_deleteLanguageFile' and 'zetra_deleteFontsFile' functions. Specifically, the plugin fails to properly restrict pathname inputs, leading to a CWE-22 'Path Traversal' flaw. This allows unauthenticated attackers to craft requests that delete arbitrary files on the server by manipulating the file path parameters. Since the plugin does not verify or sanitize the file paths before deletion, attackers can traverse directories outside the intended restricted folder and delete language files or potentially other files accessible by the web server user. The vulnerability affects all versions of the Envolve Plugin up to and including version 1.0. The CVSS v3.1 base score is 5.3, reflecting a medium severity level, with an attack vector of network (AV:N), no privileges required (PR:N), no user interaction needed (UI:N), and impact limited to integrity (I:L) without affecting confidentiality or availability. No known exploits are reported in the wild yet, and no official patches have been linked. This vulnerability could be exploited remotely without authentication, making it a significant risk for WordPress sites using this plugin. The primary impact is the unauthorized deletion of files, which could disrupt site functionality, cause loss of localization resources, or be leveraged as part of a broader attack chain if critical files are deleted.

For European organizations running WordPress sites with the Envolve Plugin, this vulnerability poses a risk of unauthorized file deletion that could degrade website functionality, particularly affecting multilingual capabilities if language files are removed. This could lead to service disruptions, loss of user trust, and potential reputational damage. While the vulnerability does not directly compromise confidentiality or availability, the integrity impact could indirectly affect availability if critical files are deleted, causing site errors or downtime. Organizations in sectors relying heavily on web presence—such as e-commerce, media, government, and education—may face operational challenges. Additionally, the unauthenticated nature of the exploit means attackers can attempt exploitation at scale, increasing risk. European organizations with strict data protection regulations (e.g., GDPR) must consider the potential indirect impacts on data integrity and service continuity. The lack of known exploits currently reduces immediate risk but does not eliminate the threat, as attackers may develop exploits rapidly once details are public.

1. Immediate mitigation involves disabling or uninstalling the Envolve Plugin until a patched version is released. 2. Monitor web server logs for suspicious requests targeting the 'zetra_deleteLanguageFile' and 'zetra_deleteFontsFile' functions or unusual file deletion activity. 3. Implement Web Application Firewall (WAF) rules to detect and block path traversal attempts, specifically filtering requests with directory traversal patterns (e.g., '../'). 4. Restrict file system permissions for the web server user to limit the scope of deletable files, ensuring that only necessary plugin directories are writable. 5. Regularly back up website files and databases to enable quick restoration if unauthorized deletions occur. 6. Follow ThemeKalia and WordPress security advisories closely for official patches and apply updates promptly once available. 7. Conduct security audits of other installed plugins to identify similar path traversal or file deletion vulnerabilities. 8. Educate site administrators on the risks of installing unverified plugins and the importance of timely updates.
