CVE-2022-24259Public exploitNetwork attack vector

Unauthenticated privilege escalation via cdr.php session check

Published Feb 4, 2022 · Updated Aug 3, 2024

Improper authentication in Voipmonitor GUI before 24.96 allows remote attackers to escalate privileges via a crafted request. The cdr.php script creates a session with auth_user set to cdr_temp when requested directly, and session checks trust that value without establishing a legitimate login. The flaw is reachable without credentials over the web interface and can grant elevated application access, with confidentiality, integrity, and availability impact assessed as high.
