Administrator-browser script execution via reflected protocol parameter
Published Feb 19, 2026 · Updated Feb 19, 2026
Reflected XSS in Comodo Dome Firewall 2.7.0 allows remote attackers to execute JavaScript in administrator browsers via crafted QoS requests. The /manage/qos/rules/ handler returns the POST protocol value without neutralizing executable script markup in the response. No attacker authentication is required, but an administrator must process the crafted request; execution remains confined to that browser context.
