AI Analysis

Impact

The vulnerability allows an attacker who can reach the web management interface on the Beetel 777VR1 to use hard‑coded administrative credentials that are embedded in the firmware. Because the login credentials are trivial, an authenticated attacker can gain full control of the device and change configuration settings, potentially exposing the network or disabling services.

Affected Systems

Beetel 777VR1 routers with firmware versions up to 01.00.09 are impacted. No newer revisions have been confirmed to be affected.

Risk and Exploitability

The CVSS base score is 8.7, indicating high severity. EPSS is reported as less than 1 %, meaning exploitation is considered uncommon but still possible. The vulnerability is not listed in the CISA KEV catalog. Attackers must have local network access to reach the vulnerable web interface; once accessed they can log in with the hard‑coded credentials and modify settings.
