IMPACT:
Security Bypass

>From local network

OPERATING SYSTEM:

DESCRIPTION:
Atom Smasher has reported a security issue in UTStarcom iAN-02EX,
which can be exploited by malicious people to bypass certain security
restrictions.

The problem is that the ATA (Analog Terminal Adaptor) can be reset by
dialing "*#26845#". This can be exploited to gain access to the ATA by
supplying the default password.

Successful exploitation requires access to a phone connected to the
ATA.

The security issue has been reported in a configuration shipped by
the Lingo VoIP (Voice over IP) provider. Configurations shipped by
other providers may also be affected.

SOLUTION:
Grant only trusted users access to phones connected to the ATA.
