Vulnerability from github – Published: 2026-08-10 21:32 – Updated: 2026-08-10 21:32

Details

A hard-coded or default root account credential in TBEA TLogger V2.1.0.0B0.0.0.0 allows an unauthenticated remote attacker to obtain root-level access to the device via the exposed SSH service. The root password can be recovered from the password hash stored in /etc/shadow and used to authenticate to the SSH service. Successful exploitation provides full administrative control of the affected device.

Severity

9.3 (Critical)


                  
                    CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N
