DescriptionCVE.org

Improper Input Validation vulnerability in Centreon Centreon Open Tickets on Central Server on Linux (Centreon Open Tickets modules).This issue affects Centreon Open Tickets on Central Server: from all before 25.10; 24.10;24.04.

Executive ViewAI

Why It Matters

A critical input validation vulnerability in Centreon Open Tickets (CVSS 9.1) affects all versions before 25.10, 24.10, and 24.04, potentially allowing attackers to compromise the Central Server. Organizations running affected Centreon versions face immediate risk of unauthorized access, data breach, or system takeover, requiring urgent mitigation since no patch is currently available.

Business Impact: Severe

Compensating Controls

Disable the Centreon Open Tickets module if not operationally critical; implement Web Application Firewall (WAF) rules to filter malicious input patterns; restrict network access to the Central Server via firewall rules (IP whitelisting); segment the Central Server from untrusted networks; enable enhanced logging and SIEM monitoring for the affected module; require multi-factor authentication for Centreon administrative access; prepare rollback procedures and maintain offline backups.
