How to Fix CVE-2022-29712

To remediate this vulnerability, upgrade all affected Librenms/librenms dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

librenms/librenms fixed: 22.4.0 
Upgrade librenms/librenms to 22.4.0
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

inspect dependencies for librenms/librenms

How to Check if You Are Affected

To determine whether your application is affected by CVE-2022-29712, inspect your project dependencies for Librenms/librenms:

inspect dependencies for librenms/librenms

Analyze the terminal output to locate any version of Librenms/librenms in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 22.4.0), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection'), where the product constructs all or part of a command, data structure, or record using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify how it is parsed or interpreted when it is sent to a downstream component. In Librenms/librenms, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.
