How to Fix CVE-2019-12465

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: 1.53 
Upgrade librenms/librenms to 1.53
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-2019-12465, 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 1.53), 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-89: Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection'), where the product constructs all or part of an sql command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended sql command when it is sent to a downstream component. without sufficient removal or quoting of sql syntax in user-controllable inputs, the generated sql query can cause those inputs to be interpreted as sql instead of ordinary user data. 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.

Source Advisory Statement

An issue was discovered in LibreNMS 1.50.1. A SQL injection flaw was identified in the ajax_rulesuggest.php file where the term parameter is used insecurely in a database query for showing columns of a table, as demonstrated by an ajax_rulesuggest.php?debug=1&term= request.
