Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection'), where the product constructs all or part of an os command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended os command when it is sent to a downstream component. In Duplicate Advisory, 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.

Source Advisory Statement

## Duplicate Advisory This advisory has been withdrawn because it is a duplicate of GHSA-pr3g-phhr-h8fh. This link is maintained to preserve external references. ## Original Description LibreNMS versions before 26.3.0 are affected by an authenticated remote code execution vulnerability by abusing the Binary Locations config and the Netcommand feature. Successful exploitation requires administrative privileges. Exploitation could result in compromise of the underlying web server.
