Lifecycle Timeline
3DescriptionCVE.org
Endian Firewall version 3.3.25 and prior allow stored cross-site scripting (XSS) via the DOMAIN parameter to /cgi-bin/smtpdomains.cgi. An authenticated attacker can inject arbitrary JavaScript that is stored and executed when other users view the affected page.
AnalysisAI
Stored cross-site scripting in Endian Firewall versions 3.3.25 and prior allows authenticated attackers to inject arbitrary JavaScript via the DOMAIN parameter in /cgi-bin/smtpdomains.cgi, which is executed when other users view the affected page. The vulnerability requires user interaction and authenticated access but can impact session security and administrative controls. No public exploit code or active exploitation has been identified at time of analysis.
Technical ContextAI
This vulnerability is a classic stored (persistent) cross-site scripting vulnerability classified under CWE-79, where user-supplied input is not properly sanitized before being stored in the application and later rendered in HTML responses. The affected parameter (DOMAIN) in the SMTP domains management CGI script fails to encode or validate user input, allowing attackers to embed malicious JavaScript payloads. When other authenticated users access the smtpdomains.cgi page, the injected script executes in their browser context with the privileges of the authenticated session. Endian Firewall is a network security appliance that manages security policies and configurations; the vulnerability exists in its web-based administrative interface.
RemediationAI
Organizations using Endian Firewall should upgrade to the latest available version beyond 3.3.25 as provided by Endian; consult the vendor advisory at https://help.endian.com/hc/en-us/sections/360004371358-Community and https://www.vulncheck.com/advisories/endian-firewall-cgi-bin-smtpdomains-cgi-domain-stored-cross-site-scripting for patched release versions. As an interim workaround pending patching, restrict administrative access to the firewall's web interface to trusted IP addresses and minimize the number of users with authenticated access to the configuration pages. Additionally, review firewall audit logs for any suspicious DOMAIN parameter values containing script tags or JavaScript syntax that may indicate exploitation attempts.
