CVE-2022-2070

Grandstream GSD3710 Stack-based Buffer Overflow

Published Sep 23, 2022 CVSS 3.1 · 9.8 Critical EPSS 5.8% KEV · Not listed

Description

In Grandstream GSD3710 in its 1.0.11.13 version, it's possible to overflow the stack since it doesn't check the param length before using the sscanf instruction. Because of that, an attacker could create a socket and connect with a remote IP:port by opening a shell and getting full access to the system. The exploit affects daemons dbmng and logsrv that are running on ports 8000 and 8001 by default.
