AI-analyzed exploit summary This Metasploit module exploits a privilege escalation vulnerability in MagniComp SysInfo by abusing the .mcsiwrapper SUID executable to load a malicious config file, leading to arbitrary code execution as root.

Description

A Local Privilege Escalation Vulnerability in MagniComp's Sysinfo before 10-H64 for Linux and UNIX platforms could allow a local attacker to gain elevated privileges. Parts of SysInfo require setuid-to-root access in order to access restricted system files and make restricted kernel calls. This access could be exploited by a local attacker to gain a root shell prompt using the right combination of environment variables and command line arguments.
