Description

TBEA TLogger V2.1.0.0B0.0.0.0 contains an authentication bypass in its web server. After a user has previously authenticated to the device, an unauthenticated attacker can directly access protected functionality through the /index.asp endpoint without providing valid credentials.

Logging out from the bypassed state can additionally cause the web server to crash.
