CVE-2025-34312Public exploitNetwork attack vector

Authenticated command execution via unsanitized blacklist name

Published Oct 28, 2025 · Updated Oct 28, 2025

Command injection in IPFire before 2.29 allows remote authenticated users to execute commands as nobody through a crafted blacklist name. The urlfilter.cgi blacklist installer interpolates BE_NAME directly into a shell invocation without filtering shell metacharacters. Access to the authenticated blacklist editor is required, and injected commands run with the privileges of the nobody account.
