CVE-2009-1556

TITLE

Linksys WVC54GC NetCamPlayerWeb11gv2 ActiveX control stack buffer overflow

DESCRIPTION

img/main.cgi on the Cisco Linksys WVC54GCA wireless video camera with firmware 1.00R22 and 1.00R24 allows remote authenticated users to read arbitrary files in img/ via a filename in the next_file parameter, as demonstrated by reading .htpasswd to obtain the admin password, a different vulnerability than CVE-2004-2507. The Linksys WVC54GC NetCamPlayerWeb11gv2 ActiveX control contains a stack buffer overflow, which may allow a remote, unauthenticated attacker to execute arbitrary code on a vulnerable system. The Linksys WVC54GC wireless video camera insecurely sends initial configuration information over the network, which can allow a remote, unauthenticated attacker to intercept video streams, access wireless network authentication credentials, modify the device firmware, or cause a denial-of-service to the video camera. Linksys WVC54GCA Wireless-G Internet Home Monitoring Camera is prone to an information-disclosure vulnerability. Exploiting this issue can allow a remote attacker to harvest sensitive information such as the administrator's password, which can lead to a complete compromise of the device. Linksys WVC54GCA Wireless-G Internet Home Monitoring Camera firmware 1.00R22 and 1.00R24 are affected; other versions may also be vulnerable. The Linksys WVC54GCA management console does not properly filter the next_file parameter submitted by the main.cgi program, and remote attackers can retrieve the contents of the current directory by submitting malicious requests. If the contents of .htpasswd are retrieved, the user can perform arbitrary operations by logging into the console without authorization. ---------------------------------------------------------------------- Secunia is pleased to announce the release of the annual Secunia report for 2008.

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. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site. The vulnerabilities are reported in firmware versions 1.00R22 and 1.00R24. 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.
