CVE-2022-2070 is a critical-severity vulnerability rated 9.8/10 on the CVSS scale. 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. EPSS estimates a 4.30% chance of exploitation in the next 30 days.
