CVE-2023-51633
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedCentreon sysName Cross-Site Scripting Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Centreon. User interaction is required to exploit this vulnerability. The specific flaw exists within the processing of the sysName OID in SNMP. The issue results from the lack of proper validation of user-supplied data, which can lead to the injection of an arbitrary script. An attacker can leverage this vulnerability to execute code in the context of the service account. Was ZDI-CAN-20731.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysisUntrusted input is placed into a web page without being neutralised, so an attacker's markup or script executes in another user's browser. That can hijack sessions, capture keystrokes, or silently perform actions as the victim. Fixing it properly means context-aware output encoding everywhere data meets HTML, backed by a content-security policy as a second line of defence.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.

Centreon Web 22.10.15 (or 23.04.10 or 23.10.1 depending on your branch)
- 1. Identify the currently installed Centreon Web version using 'rpm -qa | grep centreon-web' or checking the Centreon administration interface.
- 2. Based on your current version, upgrade to the corresponding fixed release: 22.10.15, 23.04.10, or 23.10.1.
- 3. For Debian/Ubuntu-based systems: apt-get update && apt-get install centreon-web or apt-get upgrade centreon-web.
- 4. For RHEL/CentOS-based systems: yum update centreon-web or dnf update centreon-web.
- 5. After upgrade, clear browser cache and any stored SNMP credentials to avoid re-submitting malicious data.
- 6. Verify the upgrade was successful by checking the Centreon version in the administration interface.
