Vulnerability Note VU#528993

Overview

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.

Description

The Linksys WVC54GC wireless video camera uses 916/udp for remote management commands. When a certain packet is delivered to that port, the device responds with a packet that contains the majority of the device's configuration. This packet includes details such as username, password, wireless ssid, WEP key, WEP password, WPA key, and DNS server. This packet is sent over the network unencrypted, which can allow an attacker to obtain these details.

Impact

By delivering a specially crafted packet to 916/udp of an affected device, a remote, unauthenticated attacker may be able to obtain information to intercept video streams, access wireless network authentication credentials, modify the device firmware, or cause a denial-of-service to the video camera.
