CVE-2024-12687
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 · uneditedDeserialization of Untrusted Data vulnerability in PlexTrac (Runbooks modules) which allows Object Injection and arbitrary file writes. This issue affects PlexTrac: from 1.61.3 before 2.8.1.
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 · high confidenceA deserialization vulnerability in PlexTrac's Runbooks module allows attackers to inject malicious serialized objects, leading to arbitrary file writes on the server. This can enable remote code execution. The flaw affects versions 1.61.3 through 2.8.0.

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.
-
Determine installed PlexTrac versionAccess the PlexTrac web interface and navigate to the settings or about page to view the version number. Alternatively, check the application's API endpoint for version information or review server logs that may contain version strings.Affected if The installed version falls within the range of 1.61.3 through 2.8.0 (versions >= 1.61.3 and < 2.8.1)
-
Verify Runbooks module is activeLog into PlexTrac and confirm the Runbooks module is present and accessible in the navigation or dashboard. Check if the Runbooks functionality is listed among enabled features.Affected if The Runbooks module is enabled and accessible to users
-
Check for unauthorized file modificationsReview server filesystem for unexpected new files in web-accessible directories or system locations that coincide with Runbooks module access times. Compare file hashes of known legitimate application files.Affected if New or modified files exist that were not created by legitimate administrative actions
-
Audit Runbooks execution logsExamine PlexTrac application logs for Runbooks module activity, focusing on timestamps, executed commands, and any serialized object payloads that appear unusual or encoded.Affected if Log entries show suspicious serialized data or unexpected Runbooks executions
A user is affected if their PlexTrac installation version is 1.61.3 or higher but lower than 2.8.1 AND the Runbooks module is enabled and exposed.

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 · scoped2.8.1
Upgrade PlexTrac to version 2.8.1 or later. If immediate upgrading is not feasible, restrict network access to the Runbooks module and monitor for indicators of compromise.
2.8.1 or later
- Review the current PlexTrac version to confirm it falls within the affected range (1.61.3 through 2.8.0)
- Consult PlexTrac upgrade documentation at docs.plextrac.com for version-specific upgrade procedures
- Create a complete backup of the PlexTrac database and configuration files before upgrading
- Upgrade PlexTrac to version 2.8.1 or later
- Verify the upgrade was successful by checking the PlexTrac version
- Test the Runbooks module functionality to confirm the vulnerability is resolved
