VAR-200511-0313

Vulnerability from variot - Updated: 2024-02-13 22:41

Cisco IP Phone (VoIP) 7920 1.0(8) contains certain hard-coded ("fixed") public and private SNMP community strings that cannot be changed, which allows remote attackers to obtain sensitive information. This could allow remote attackers to retrieve and modify the device configuration. Cisco 7920 Wireless IP Phones running firmware version 1.0(8) and earlier are vulnerable to this issue. This can be exploited to retrieve and modify the device configuration, including stored user data such as phone book entries by sending SNMP GetRequest or SetRequest to phone.

2) The IP phone listens on port 17185/udp to allow connections from the VxWorks debugger. This may be exploit to collect debugging information or to cause a DoS on the device.

SOLUTION: Apply firmware update. http://www.cisco.com/warp/public/707/cisco-sa-20051116-7920.shtml#software

PROVIDED AND/OR DISCOVERED BY: Reported by vendor.
