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. This allows the attacker to access functionality intended for authenticated users and may expose or modify device configuration and data. Logging out from the bypassed state can additionally cause the web server to crash.
