CVE-2026-30808
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 · uneditedSession Fixation vulnerability allows Session Hijacking via crafted session ID. This issue affects Pandora FMS: from 777 through 800
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 analysis · moderate confidenceSession Fixation vulnerability in Pandora FMS allows attackers to pre-set a user's session ID before authentication. Once the user logs in, the attacker can hijack the authenticated session using the predetermined session ID, enabling unauthorized access to the victim's account.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify installed Pandora FMS versionDetermine the version of Pandora FMS currently running in your environment through the web interface, admin panel, or system filesAffected if The installed version is below 777.17, or is 778 or higher but below 802
-
Verify session ID behavior on authenticationTest or inspect session handling - capture a session ID before login, authenticate, then check if a new session ID is generated or if the original ID persistsAffected if The same session ID used before authentication continues to be used after successful login (no regeneration occurs)
Your environment is affected if Pandora FMS version is within the range 777.17 or below, or between 778 and 801, AND session IDs are not regenerated when users authenticate.
Generated from the published advisory. Verify against your own configuration.
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.
dbcve · scoped777.17802
Regenerate session IDs upon user authentication and implement session ID validation to prevent fixation attacks. Update to a patched version beyond 800 if available.
Version 802 or later
- 1. Back up your current Pandora FMS database and configuration files
- 2. Download Pandora FMS version 802 or later from the official pandorafms.com downloads area
- 3. Review the official upgrade documentation for your current version
- 4. Execute the upgrade following the documented migration path
- 5. Verify the session handling works correctly post-upgrade
- 6. Confirm the version number has been updated post-installation
