This is related to Firmware 01.11.2017-11:43:44, Boot v0.70.03, Modem 5.4.1.10.1.1A, Hardware 02, and Arcadyan ARV7519RW22-A-L T VR9 1.2.

Technical Analysis

CVE-2018-20377 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.

The vulnerability requires no privileges and no user interaction, making it a prime target for automated exploitation campaigns and worm-like propagation.

A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 9.8.
