XSS

Description

Endian Firewall version 3.3.25 and prior allow stored cross-site scripting (XSS) via the remark parameter to /cgi-bin/snat.cgi. An authenticated attacker can inject arbitrary JavaScript that is stored and executed when other users view the affected page.

Analysis

Stored XSS in Endian Firewall 3.3.25 and prior allows authenticated attackers to inject malicious JavaScript via the remark parameter in /cgi-bin/snat.cgi, which persists and executes when other administrators or users access the affected page. The vulnerability requires low-privilege authentication and user interaction (page view), limiting immediate impact but creating persistent data integrity and session hijacking risks within the appliance administrative interface.
