Administrator-targeted script execution via unencoded settings values
Published Apr 1, 2024 · Updated Mar 12, 2025
Cross-site scripting in Clavister NetWall E10 and E80 14.00.0 through 14.00.10 allows attackers to execute browser script. The Misc Settings endpoint relies on front-end character validation, accepts eight manipulated settings in a forged HTTP POST, and renders the supplied values as executable JavaScript. Exploitation requires a logged-in administrator to open an attacker-controlled page, allowing unauthorized actions within that administrator's browser session.
