CVE-2025-34304 | IPFire < v2.29 SQL Injection via OpenVPN Connection Logs

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.

6.5 3.1 MEDIUM
CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N Click to expand
Attack vector (AV:N)
Could be attacked over the internet or any normal routed network—not just someone sitting at the machine.
Attack complexity (AC:L)
Once they can reach the bug, pulling it off is straightforward—no weird race conditions or rare setup.
Privileges required (PR:L)
A normal user session is enough; they don’t have to be admin.
User interaction (UI:N)
Nobody has to click “OK” or open a trap file; it can work without a victim helping.
Scope (S:U)
Damage stays in the same “trust bubble” as the broken component—no big spill into unrelated systems.
Confidentiality (C:H)
Serious risk that confidential data gets exposed in a big way.
Integrity (I:N)
Data isn’t meaningfully altered or forged.
Availability (A:N)
Service keeps running; no real outage angle.
