⚠️ Risk & Real-World Impact
Worst Case
An authenticated CentreonBI user could execute arbitrary scripts with server privileges, leading to complete system compromise, data exfiltration, or lateral movement within the monitoring infrastructure.
Likely Case
Privilege escalation within the Centreon environment, unauthorized access to monitoring data, or disruption of monitoring services.
If Mitigated
Limited impact if proper access controls, network segmentation, and least privilege principles are enforced for CentreonBI accounts.
🎯 Exploit Status
Exploitation requires authenticated access as CentreonBI user. No public exploit code available at this time.

🔧 Temporary Workarounds
Restrict CentreonBI Account Access
linuxTemporarily restrict or disable CentreonBI user accounts until patching can be completed.
usermod -L centreonbi
passwd -l centreonbi
Implement Network Segmentation
allIsolate the MBI server from other critical systems to limit potential lateral movement.
🧯 If You Can't Patch
- Implement strict access controls for CentreonBI accounts and monitor their activity closely.
- Apply network segmentation to isolate the MBI server and implement additional monitoring for suspicious script execution.
🔍 How to Verify
Check if Vulnerable:
Check Centreon version via web interface or command line. Verify if running affected version range.Check Version:
rpm -qa | grep centreon-web or dpkg -l | grep centreon-webVerify Fix Applied:
Confirm version is updated to 24.10.6, 24.04.9, or 23.10.15. Test CentreonBI user permissions for script embedding capabilities.📡 Detection & Monitoring
