CVE-2025-34312 IPFire < v2.29 Command Injection via URL Filter Blacklist

What is CVE-2025-34312?

CVE-2025-34312 is a high-severity command injection vulnerability in IPFire.org IPFire, published on 28 Oct 2025. Any signed-in user can exploit it over the network, with no action from the victim.

Official description

IPFire versions prior to 2.29 (Core Update 198) contain a command injection vulnerability that allows an authenticated attacker to execute arbitrary commands as the 'nobody' user via the BE_NAME parameter when installing a blacklist. When a blacklist is installed the application issues an HTTP POST to /cgi-bin/urlfilter.cgi and interpolates the value of BE_NAME directly into a shell invocation without appropriate sanitation. Crafted input can inject shell metacharacters, leading to arbitrary command execution in the context of the 'nobody' user.
