TITLE

Linksys WVC54GC NetCamPlayerWeb11gv2 ActiveX control stack buffer overflow

DESCRIPTION

Stack-based buffer overflow in the SetSource method in the NetCamPlayerWeb11gv2 ActiveX control in NetCamPlayerWeb11gv2.ocx on the Cisco Linksys WVC54GC wireless video camera before firmware 1.25 allows remote attackers to execute arbitrary code via long invalid arguments. Linksys WVC54GC NetCamPlayerWeb11gv2 Agent ActiveX Control is prone to a buffer-overflow vulnerability because the application fails to adequately check boundaries on user-supplied input. Failed attacks will likely cause denial-of-service conditions. WVC53GC with firmware versions prior to 1.25 that include the ActiveX control are vulnerable. Linksys WVC54GC is a wireless network camera that supports 802.11g protocol. If a user is tricked into browsing a specially crafted HTML document and provides a very long input parameter to the method, it can trigger a stack overflow, causing the browser to crash or execute arbitrary commands. ---------------------------------------------------------------------- Secunia is pleased to announce the release of the annual Secunia report for 2008.

This is related to vulnerability #1 in: SA33032 2) Input passed to the "next_file" parameter in img/main.cgi is not properly verified before being used to read files. This can be exploited to read the .htpasswd file from the current directory and disclose the administrator's password. Successful exploitation of this vulnerability requires valid user credentials. 3) Input passed to the "next_file" parameter in img/main.cgi, main.cgi, and adm/file.cgi is not properly sanitised before being returned to the user. Other versions may also be affected. SOLUTION: Use the product in trusted networks only. Filter malicious characters and character sequences in a web proxy.

This can be exploited to cause a stack-based buffer overflow by e.g. tricking a user into visiting a malicious website. SOLUTION: Update to version 1.25.
