Description:
Joffrey Czarney has reported a weakness in Cisco Unified IP Phones, which can be exploited by malicious people to bypass certain security restrictions.
The problem is that the Extension Mobility authentication credentials are not encrypted when communicating with the internal web server of an IP phone. This can be exploited to sniff the authentication credentials and perform various actions on a target IP phone (e.g. remotely login/logout a user or eavesdrop on calls).
Successful exploitation requires that the Extension Mobility feature is enabled (not enabled by default).
The weakness affects all Cisco IP Phones that support the Extension Mobility feature.
