CVE Reference(s):

Description


Some vulnerabilities have been reported in TANDBERG Video Communication Server, which can be exploited by malicious users to disclose sensitive information, and by malicious people to conduct cross-site scripting and hijacking attacks, or to compromise a vulnerable appliance.

1) The same pair of known SSH host keys is used for all installations. This can be exploited to potentially hijack an already established SSH session via Man-in-the-Middle (MitM) attacks.

2) Input passed to the "page" parameter in helppage.php and /user/helppage.php is not properly sanitised before being used to read files. This can be exploited to read arbitrary files from local resources via directory traversal attacks.

3) The cookie used for identifying a user to the web interface is insecurely generated from predictable values. This can be exploited to gain administrative access to the web interface and potentially execute arbitrary code by applying a custom software update.

4) Certain unspecified input is not properly sanitised before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.

5) An unspecified error can be exploited to execute arbitrary code. No further information is currently available.


Solution:
Update the firmware to version x5.1.1. Vulnerability #3 was reportedly first fixed in version x4.3.0.
