CVE-2025-34330 is a medium-severity vulnerability affecting AudioCodes Fax Server and Auto-Attendant IVR appliances up to version 2.6.23. It allows an unauthenticated attacker to upload or overwrite files via a web administration component, specifically the ajaxPromptUploadFile.php endpoint, due to a lack of authentication, authorization, and file-type validation. This could lead to tampering with IVR audio content or facilitating further attacks. The CVSS score is 5.3 (MEDIUM), indicating a network-based attack with low complexity and a potential impact on integrity. There is currently no known active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage.
