AI-analyzed exploit summary This PowerShell script exploits CVE-2020-7352, a vulnerability in GOG Galaxy's GalaxyClientService, by sending a crafted payload to a local TCP port (9978) to achieve remote code execution (RCE). The payload includes a command to add a new user to the system, demonstrating the exploit's functionality.
Description
The GalaxyClientService component of GOG Galaxy runs with elevated SYSTEM privileges in a Windows environment. Due to the software shipping with embedded, static RSA private key, an attacker with this key material and local user permissions can effectively send any operating system command to the service for execution in this elevated context. The service listens for such commands on a locally-bound network port, localhost:9978. A Metasploit module has been published which exploits this vulnerability. This issue affects the 2.0.x branch of the software (2.0.12 and earlier) as well as the 1.2.x branch (1.2.64 and earlier). A fix was issued for the 2.0.x branch of the affected software.

This PowerShell script exploits CVE-2020-7352, a vulnerability in GOG Galaxy's GalaxyClientService, by sending a crafted payload to a local TCP port (9978) to achieve remote code execution (RCE). The payload includes a command to add a new user to the system, demonstrating the exploit's functionality.
This Metasploit module exploits a privilege escalation vulnerability in GOG GalaxyClientService by sending a crafted payload to the service, which executes arbitrary code with SYSTEM privileges. The exploit leverages a hardcoded HMAC-SHA512 key to sign the payload and communicates with the service over a local TCP socket.
