Lifecycle Timeline
2DescriptionCVE.org
LibreNMS 1.46 contains an authenticated SQL injection vulnerability in the MAC accounting graph endpoint that allows remote attackers to extract database information. Attackers can exploit the vulnerability by manipulating the 'sort' parameter with crafted SQL injection techniques to retrieve sensitive database contents through time-based blind SQL injection.
Executive ViewAI
LibreNMS deployments are vulnerable to authenticated SQL injection attacks that could allow legitimate users to extract sensitive database information, including credentials and network configuration data. This poses a direct risk to organizations relying on LibreNMS for network monitoring and management, particularly if admin accounts are compromised or if the system is accessed by untrusted internal users.
Restrict network access to LibreNMS via firewall rules or VPN to trusted administrators only; disable the MAC accounting graph feature entirely if not operationally required; implement Web Application Firewall (WAF) rules to detect and block SQL injection patterns in graph endpoint requests; enforce strong authentication and monitor for unusual database queries; conduct regular database backups and implement intrusion detection signatures for SQL injection attempts.
