Security readout for executives and security teams
Plain-English summary
Centreon Open Tickets has a critical path traversal vulnerability affecting Central Server deployments on Linux. A logged-in attacker could potentially access or modify files outside intended locations, creating risk to monitoring operations and sensitive data. The sources do not show confirmed active exploitation.
Executive priority
Treat as urgent for affected Centreon environments. The vulnerability is critical, impacts core monitoring infrastructure, and requires only low privileges. Prioritize version validation and upgrade planning, but avoid assuming active exploitation without new evidence.
Technical view
CVE-2026-2749 is a path traversal issue in Centreon Open Tickets on Central Server. It affects versions before 25.10.3, 24.10.8, and 24.04.7. CVSS 3.1 is 9.9: network-accessible, low complexity, low privileges required, no user interaction, changed scope, with high confidentiality, integrity, and availability impact.
Likely exposure
Exposure is likely limited to organizations running Centreon Open Tickets on a Linux Central Server, especially where authenticated users can reach the module over the network. Confirm whether the module is installed and whether versions are below the fixed releases.
Exploitation context
The CVE record indicates low-privilege authenticated network exploitation is possible. The provided sources do not include public exploit details and do not indicate CISA KEV listing or confirmed exploitation in the wild.
Researcher notes
Public details are limited in the provided sources. The CVSS vector suggests an authenticated path traversal with broad impact and scope change. Do not infer exploit mechanics beyond the advisory. Track the vendor bulletin and CVE record for clarifications or additional indicators.
Mitigation direction
- Upgrade Centreon Open Tickets to 25.10.3, 24.10.8, 24.04.7, or later as applicable.
- Review the Centreon security bulletin for any deployment-specific guidance.
- Restrict access to Centreon Open Tickets to trusted users and networks where possible.
- Review Centreon user privileges and remove unnecessary module access.
Validation and detection
- Inventory Centreon Central Server systems running Centreon Open Tickets.
- Check installed Open Tickets version against 25.10.3, 24.10.8, or 24.04.7.
- Confirm whether the service is reachable from untrusted networks.
- Review logs for unusual authenticated file access or module errors.
- Document remediation status for each affected Centreon instance.
