Insecure Permissions vulnerability in Tenda CP3 Pro Firmware V22.5.4.93 allows the telnet service (telnetd) by default at boot via the initialization script /etc/init.d/eth.sh. This allows remote attackers to connect to the device s shell over the network, potentially without authentication if default or weak credentials are present
The product uses weak credentials (such as a default key or hard-coded password) that can be calculated, derived, reused, or guessed by an attacker.
