CVE-2022-25172Public exploitNetwork attack vector

Session hijacking via script-readable authentication cookie

Published May 12, 2022 · Updated Apr 15, 2025

Information disclosure in InHand Networks InRouter302 3.5.4 allows remote attackers to steal web sessions through injected JavaScript. The login success handler writes the web_session value through document.cookie without HttpOnly, leaving it readable to page scripts. Exploitation requires JavaScript execution in an authenticated administrator's browser; the stolen cookie grants access to the router's web interface.
