VAR-200906-0230

Vulnerability from variot - Updated: 2025-04-10 22:56

Directory traversal vulnerability in cgi-bin/webcm in the administrative web interface on the Netgear DG632 with firmware 3.4.0_ap allows remote attackers to list arbitrary directories via a .. (dot dot) in the nextpage parameter. NetGear DG632 router is prone to multiple remote vulnerabilities. The Netgear DG632 router runs a web interface on port 80, allowing administrators to log in and manage the device's settings. Authentication to this web interface is handled by a script named webcm in /cgi-bin/, which redirects to relevant pages based on the user's authentication status. The webcm script handles user authentication and tries to load indextop.htm via the following javascript. The indextop.htm page requires HTTP Basic Authentication. --- function loadnext() { //document.forms[0].target.value="top"; document.forms[0].submit() ; //top.location.href="../cgi-bin/webcm?nextpage=../html/indextop.htm"; } Loading file ... --- If a valid username for the default admin user is provided, the script will continue to load the indextop.htm page and load other frames based on hidden fields; if the user authentication fails, it will return to "../cgi-bin/webcm" . Normal use: http://TARGET_IP/cgi-bin/webcm?nextpage=../html/stattbl.htm This will ask the user to authenticate and deny access to this file if the authentication details are unknown. The same stattbl.htm file can be accessed without providing any credentials using the following URL: http://TARGET_IP/html/stattbl.htm
