Description


Shawn Merdinger has reported some vulnerabilities in UTStarcom F1000 Wi-Fi Handset, which can be exploited by malicious people to gain access to potentially sensitive information, to modify certain information, and to cause a DoS (Denial of Service).

1) The SNMP service that runs on the IP phone allows read access using default public credential. The service cannot be disabled and does not allow the community string to be changed. This can be exploited to retrieve the device configuration by sending SNMP GetRequest to the phone. The SNMP service reportedly can be crashed when accessed via snmpwalk.

2) A rlogin service runs on port 513/tcp of the phone and can be accessed without requiring logon. The service cannot be disabled and does not allow login credentials to be set. This can be exploited to gain access to the Vxworks OS, potentially allowing retrieval and modification of configuration information and rebooting the device, thus causing a DoS.

The vulnerabilities have been reported in version 2.0 with VxWorks version 5.5.1 and WIND kernel version 2.6.

Note: A telnet service runs on 23/tcp with publicly known default userid and password.


Solution:
The vulnerabilities have reportedly been fixed in version 3.1.
