"A vulnerability in the web-based management interface of Session
Initiation Protocol (SIP) Software for Cisco IP Phone 8800 Series
could allow an authenticated, remote attacker to write arbitrary files
to the filesystem. The vulnerability is due to insufficient input
validation and file-level permissions. An attacker could exploit this
vulnerability by uploading invalid files to an affected device. A
successful exploit could allow the attacker to write files in
arbitrary locations on the filesystem. This vulnerability affects
Cisco IP Phone 8800 Series products running a SIP Software release
prior to 11.0(5) for Wireless IP Phone 8821 and 8821-EX; and
12.5(1)SR1 for the IP Conference Phone 8832 and the rest of the IP
Phone 8800 Series.
