Description:
Some vulnerabilities have been reported in various Nortel products, which can be exploited by malicious people to cause a DoS (Denial of Service) and to eavesdrop with affected devices.
1) The problem is that it is possible to send spoofed registration messages to the server to which a UNIStim IP phone is connected, forcing the IP phone to re-register. This can be exploited to cause a DoS by continuously sending re-registration messages.
2) The problem is that it is possible to send spoofed "Open Audio Stream" messages to an IP phone. This can be exploited to open an audio channel and eavesdrop with the IP phone.
The vulnerabilities are reported in the following products (see vendor advisory for details):
* BCM 4.0, BCM 3.7, BCM50
* SRG1.0, SRG1.5, SRG50
* CS1000/Meridian1
* IP Audio Conf Phone 2033
* IP Phone 1100 series
* IP Phone 200x
* IP Softphone 2050
* Mobile Voice Client 2050
NOTE: The IPCM used in CS2000 and CS2100 is not affected when the UNIStim security protocol is enabled. The vendor still investigates if MCS5100 and MCS5200 are affected by the vulnerability.
