Description
LibreNMS is an auto-discovering PHP/MySQL/SNMP based network monitoring tool. Prior to version 25.11.0, a boolean-based blind SQL injection vulnerability was identified in the LibreNMS application at the /ajax_output.php endpoint. The hostname parameter is interpolated directly into an SQL query without proper sanitization or parameter binding, allowing an attacker to manipulate the query logic and infer data from the database through conditional responses. This issue has been patched in version 25.11.0.

CWE ID Description
CWE-89 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.

Executive Summary

This vulnerability is a boolean-based blind SQL injection in LibreNMS versions prior to 25.11.0. It occurs at the /ajax_output.php endpoint where the hostname parameter is directly inserted into an SQL query without proper sanitization or parameter binding. This allows an attacker to manipulate the SQL query logic and infer data from the database by observing conditional responses.

Impact Analysis

An attacker exploiting this vulnerability can extract sensitive information from the LibreNMS database by manipulating SQL queries. This can lead to unauthorized disclosure of confidential data, potentially compromising the security and integrity of the monitored network information.

Mitigation Strategies

Upgrade LibreNMS to version 25.11.0 or later, where the boolean-based blind SQL injection vulnerability at the /ajax_output.php endpoint has been patched.
