Title: Linksys WVC54GCA Wireless-G 'SetupWizard.exe' Information Disclosure Vulnerability
Severity: CRITICAL
Description:
Linksys WVC54GCA Wireless-G Internet Home Monitoring Camera is prone to an information-disclosure vulnerability.
The device can be controlled remotely via a management interface that transmits data via UDP port 916. During an initial setup using 'SetupWizard.exe', the device sends the configuration data to the client in a secure manner. The packets contain sensitive information such as username, password, wireless SSID, WEP key, WEP password, WPA key, and DNS server. However, after the authentication credentials are received, the admin username and password can be obtained from the memory dump of the 'SetupWizard.exe' process.
Exploiting this issue can allow a remote attacker to harvest sensitive information that can aid in further attacks such as intercepting video streams, accessing wireless authentication credentials, causing a denial of service, or modifying the device's firmware.
Linksys WVC54GCA Wireless-G Internet Home Monitoring Camera firmware versions 1.00R22 and 1.00R24 are affected; other versions may also be vulnerable.
Affected Products:
- Linksys WVC54GCA 1.00R22
- Linksys WVC54GCA 1.00R24
