CVE-2025-13293Network attack vector

Root access via hard-coded SSH credential

Published Aug 10, 2026 · Updated Aug 10, 2026

Hard-coded credentials in TBEA TLogger V2.1.0.0B0.0.0.0 allow remote attackers to gain root access through the exposed SSH service. The firmware uses a recoverable, reusable root password hash in /etc/shadow while its SSH service accepts that password for the root account. Network reachability to SSH and no prior authentication are required; successful login grants full administrative control of the device.
