CVE-2025-34312
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.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (2.30%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
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.
