VENDOR:
Zyxel
PRODUCT:
ZyXel P2000W (Version 2) VoIP 802.11b Wireless Phone
http://www.zyxel.com/product/model.php?indexcate=1122437334&indexFlagvalue=1075687935
Firmware version: WV.00.02
VULNERABILITY TITLE:
Zyxel P2000W (Version 2) VoIP wireless phone undocumented port UDP/9090
DETAILS, IMPACT AND WORKAROUND:
The Zyxel P2000W (Version 2) VoIP wireless phone has an undocumented
port, 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 vulnerabiltiy to easily identiy the
phone and software version. Also, the undocumented open port may
provide an avenue for DoS.
There appears to be no workaround for this issue as far as disabling the port.
