HTTP: Cisco VoIP Phone PortInformation DOS1
This signature detects attempts to exploit a known vulnerability in Cisco VoIP phones. Versions CP-7910 and later are vulnerable. Attackers can send an arbitrarily long (120000+) StreamID to the PortInformation script to cause an error message that displays a memory dump. Attackers can use this information to reconstruct the calling patterns of a particular phone.
