CVE-2019-25402Public exploitNetwork attack vector

Browser script execution via reflected login username

Published Feb 19, 2026 · Updated Feb 19, 2026

Reflected XSS in Comodo Dome Firewall 2.7.0 allows remote attackers to execute JavaScript through the login username parameter. The /korugan/login handler reflects the POSTed username in its response without neutralizing HTML or script syntax. No authentication is required, but a user must render the crafted response; script execution remains confined to that user's browser context.
