CVE-2025-34333 Details

Description

AudioCodes Fax Server and Auto-Attendant IVR appliances versions up to and including 2.6.23 configure the web document root at C:\\F2MAdmin\\F2E with overly permissive file system permissions. Authenticated local users have modify rights on this directory, while the associated web server process runs as NT AUTHORITY\\SYSTEM. As a result, any local user can create or alter server-side scripts within the webroot and then trigger them via HTTP requests, causing arbitrary code to execute with SYSTEM privileges.
