MPM HP-180W VoIP 802.11b Wireless Desktop Phone
Firmware Version: WE.00.17
MPM HP-180W VoIP Wireless Desktop Phone undocumented port UDP/9090
DETAILS, IMPACT AND WORKAROUND:
MPM HP-180W VoIP Wireless Desktop Phone has an undocumented port and
service, UDP/9090, that provides an unauthenticated attacker
information about the phone,
specifically the phone's MAC address and software version. An attacker
can use this to remotely identify the phone and software version.
Also, the open port may provide an avenue for DoS.
There appears to be no workaround for this issue.
