CVE-2022-27280Network attack vector

Authenticated stored XSS via web_exec parameter

Published Apr 10, 2022 · Updated Aug 3, 2024

Cross-site scripting in InRouter 900 before 1.0.0.r11700 allows remote authenticated users to execute stored script in a browser via /apply.cgi. The web_exec parameter is stored without adequate output neutralization and later rendered by the router's web interface, allowing injected JavaScript to run in another user's session. Exploitation requires access to the authenticated management interface and a victim loading the affected page; the demonstrated impact is browser-side script execution with potential data access or administrative actions available to that session.
