What is CVE-2025-50975?
CVE-2025-50975 is a medium-severity cross-site scripting vulnerability in n/a, published on 26 Aug 2025. Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.
Official description
IPFire 2.29 web-based firewall interface (firewall.cgi) fails to sanitize several rule parameters such as PROT, SRC_PORT, TGT_PORT, dnatport, key, ruleremark, src_addr, std_net_tgt, and tgt_addr, allowing an authenticated administrator to inject persistent JavaScript. This stored XSS payload is executed whenever another admin views the firewall rules page, enabling session hijacking, unauthorized actions within the interface, or further internal pivoting. Exploitation requires only high-privilege GUI access, and the complexity of the attack is low.
