IPFire < v2.29 SQL Injection via OpenVPN Connection Logs

Summary

CVE	CVE-2025-34304
State	PUBLISHED
Assigner	VulnCheck
Source Priority	CVE Program / NVD first with legacy fallback

Updated	2026-10-19 13:10:00 UTC
Description	IPFire versions prior to 2.29 (Core Update 198) contain a SQL injection vulnerability that allows an authenticated attacker to manipulate the SQL query used when viewing OpenVPN connection logs via the CONNECTION_NAME parameter. When viewing a range of OpenVPN connection logs, the application issues an HTTP POST request to the Request-URI /cgi-bin/logs.cgi/ovpnclients.dat and inserts the value of the CONNECTION_NAME parameter directly into the WHERE clause without proper sanitization or parameterization. The unsanitized value can alter the executed query and be used to disclose sensitive information from the database.
