CVE-2025-34312: Ipfire

High severity, CVSS 8.8. EPSS: 2.2% chance of exploitation in the next 30 days.

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.

Affected products
