CVE-2009-4509

HIGH · CVSS 10.0EPSS 4.5%EU EUVD

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.
