CVE-2024-51187Public exploit

Stored script execution via firewall rule name

Published Nov 11, 2024 · Updated Nov 12, 2024

Stored XSS in TRENDnet TEW-651BR 2.04B1, TEW-652BRP 3.04b01, and TEW-652BRU 1.00b12 allows remote authenticated users to run scripts. The firewall rule editor stores the firewallRule_Name_1.1.1.0.0 value without neutralizing script markup and renders it when the rule page is viewed. Access to the adjacent-network management interface and low-privileged authentication are required, and a second user's page visit triggers the script.
