Description

The administrative web console on the TANDBERG Video Communication Server (VCS) before X4.3 uses predictable session cookies in (1) tandberg/web/lib/secure.php and (2) tandberg/web/user/lib/secure.php, which makes it easier for remote attackers to bypass authentication, and execute arbitrary code by loading a custom software update, via a crafted "Cookie: tandberg_login=" HTTP header.

Affected products

Vsecurity Tandberg Video Communication Server: through x4.2.1; x1.0.0, x1.1.0, x1.2.0, x2.0.0, x2.1.0, x3.0.0 (+3)
