ISS Security Advisory - Polycom ViewStation videoconferencing products contain several remote vulnerabilities which allow attackers to gather information about the device, retrieve files, crash the device, and monitor videoconferences. Polycom ViewStation 7.2 and earlier and Polycom ViewStation FX/VS 4000 version 4.1.5 and below are affected.

Internet Security Systems Security Advisory
September 4, 2002

Multiple Remote Vulnerabilities in Polycom Videoconferencing Products

Synopsis:

Internet Security Systems (ISS) X-Force has discovered multiple
vulnerabilities in the Polycom ViewStation videoconferencing products. The
ViewStation devices are powered by a proprietary operating system that
includes Web, Telnet, and FTP servers.

Impact:

The vulnerable ViewStation products are susceptible to multiple attacks that
may allow individuals to gather information about the device, retrieve files,
crash the device, or monitor videoconferences.

Affected Versions:

Polycom ViewStation 128 version 7.2 and earlier
Polycom ViewStation H.323 version 7.2 and earlier
Polycom ViewStation 512 version 7.2 and earlier
Polycom ViewStation MP version 7.2 and earlier
Polycom ViewStation DCP version 7.2 and earlier
Polycom ViewStation V.35 version 7.2 and earlier
Polycom ViewStation FX/VS 4000 version 4.1.5 and earlier

Description:

The Polycom ViewStation is configured by default with a null or empty password
for the administrator account. Users are not prompted to supply a new
administrator password during the installation process. This account allows
users to configure and manage the device as well as establish videoconference
links. This password for this account cannot be changed via the Web interface
and can only be changed via the remote control. Documentation on how to
configure a password is provided in the "Optional Configurations" section of
the Polycom ViewStation User Guide.

The integrated Web and Telnet servers are vulnerable to multiple attacks. By
encoding Web requests in Unicode, attackers may retrieve information from the
Web server without authenticating. Attackers can use this technique to
retrieve the administrator password from a vulnerable ViewStation. Once this
password is obtained, remote attackers can take control the device. This may
allow unauthorized individuals to modify the system configuration, destroy
information, and record or monitor video conferences.

The Polycom ViewStation camera is vulnerable to various types of denial of
service (DoS) attacks. The Telnet service may become unstable and crash when
multiple connection attempts are made. The Telnet service allows an unlimited
number of login attempts, which may expose it to a brute-force attack. Remote
attackers may be able to cause the camera to crash by sending long or
malformed ICMP packets.

Recommendations:

X-Force recommends that all Polycom ViewStation users configure strong
passwords on their devices and assess the general security of their devices.
If possible, ViewStation devices should reside behind a firewall.

Internet Scanner X-Press Update 6.14 includes checks to assess the
vulnerabilities described in this advisory. Detection support for these
vulnerabilities was provided in XPU 20.2 for RealSecure Network Sensor.
Internet Scanner XPU 6.14 and RealSecure Network Sensor 20.2 are available
from the ISS Download Center at: http://www.iss.net/download.

Polycom has released software version 4.2 for the Polycom ViewStation
FX/VS4000. Polycom will be releasing a patch in September for the ViewStation
and ViewStation SP products. The beta release of this patch is now available
on the Polycom FTP site. Please refer to the Polycom Worldwide Resource
Center for more information.

Additional Information:

The Common Vulnerabilities and Exposures (CVE) project has assigned the
following names to these issues. These are candidates for inclusion in the
CVE list (http://cve.mitre.org), which standardizes names for security
problems.

CAN-2002-0626 Null or empty password on ViewStation device
CAN-2002-0627 Unicode directory traversal vulnerability
CAN-2002-0628 ViewStation device telnet brute force attack
CAN-2002-0629 ViewStation telnet DoS vulnerability
CAN-2002-0630 ViewStation ICMP DoS vulnerability
