DescriptionCVE.org

A flaw has been found in Beetel 777VR1 up to 01.00.09/01.00.09_55. The affected element is an unknown function of the component UART Interface. This manipulation causes improper access controls. It is feasible to perform the attack on the physical device. The complexity of an attack is rather high. The exploitability is described as difficult. The exploit has been published and may be used. The vendor was contacted early about this disclosure but did not respond in any way.

AnalysisAI

Improper access controls in the UART interface of Beetel 777VR1 firmware (up to version 01.00.09) allow attackers with physical access to bypass authentication mechanisms, though exploitation requires high technical complexity. Public exploit code exists for this vulnerability, and no patch is currently available from the vendor despite early notification.
