CVE-2006-2561

High
Published: Translated: NVD NIST

Summary

The Edimax BR-6104K router has a vulnerability in UPnP handling that allows remote attackers to bypass access restrictions and perform unauthorized operations. By modifying the InternalClient parameter in a UPnP request, an attacker can add port forwarding rules (AddPortMapping) and redirect arbitrary network traffic.

Risk Assessment

The risk is the potential for remote control over the router's network traffic, which could lead to confidentiality and integrity breaches in the local network. An attacker can redirect traffic to malicious servers or gain access to internal resources.

Recommendation

It is recommended to immediately disable UPnP on the Edimax BR-6104K router and update the firmware to the latest version if a patch is available. If no update is available, consider replacing the device with a more secure model.

Edimax BR-6104K router allows remote attackers to bypass access restrictions and conduct unauthorized operations via a UPnP request with a modified InternalClient parameter (possibly within NewInternalClient), which is not validated, as demonstrated by using AddPortMapping to forward arbitrary traffic.
