Loading vulnerability…
A local privilege escalation vulnerability exists in MagniComp's SysInfo prior to version 10-H64 for Linux and UNIX platforms. The vulnerability arises from the use of setuid-to-root permissions in parts of SysInfo, which are required to access restricted system files and make kernel calls. A local attacker can exploit this by manipulating environment variables and command line arguments to execute arbitrary commands as root, including obtaining a root shell.

This repository contains a single Metasploit module (Ruby file) that exploits a local privilege escalation vulnerability (CVE-2017-6516) in MagniComp SysInfo versions prior to 10-H64 on Linux and Solaris. The exploit abuses the SUID '.mcsiwrapper' binary, which allows loading a configuration file with a user-controlled 'ExecPath' directive, enabling execution of arbitrary code as root. The module checks for the presence and permissions of the vulnerable binary, verifies the installed version, and uploads a malicious configuration and payload executable to a writable directory (default: /tmp). It then triggers the vulnerability to execute the payload as root, typically resulting in a root shell or meterpreter session. The module is fully integrated into the Metasploit framework, allowing for customizable payloads and automated cleanup. The only file in the repository is the exploit module itself, written in Ruby, and it is weaponized for operational use.
