Title source: llmExploitation Summary
EIP tracks 1 public exploit for CVE-2022-2070. PoCs published by Pepelux.
AI-analyzed exploit summary This exploit targets a stack buffer overflow in Grandstream GSD3710 firmware 1.0.11.13 and lower, leveraging ROP gadgets and a custom ARM reverse shell payload to achieve remote code execution. The payload bypasses memory protections via mprotect and establishes a reverse shell to the attacker's specified IP and port.
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.
