CVE-2017-3629 is part of the Stack Clash class of vulnerabilities affecting the Solaris kernel in Oracle Sun Systems Products Suite (versions 10 and 11). The vulnerability arises from improper memory management, specifically the insufficient separation between the process stack and other memory regions (such as the heap or mmap). This allows a local, low-privileged attacker to manipulate stack growth to collide with adjacent memory regions, bypassing the stack guard-page and potentially leading to privilege escalation or arbitrary code execution. The vulnerability is easily exploitable by attackers with local access to the system.

This repository contains a single Metasploit module: 'Solaris RSH Stack Clash Privilege Escalation'. The module exploits a stack clash vulnerability in the setuid /usr/bin/rsh binary on unpatched Solaris 11.1 and 11.3 (x86) systems. The exploit works by uploading and compiling a C exploit (solaris_rsh.c by Qualys) on the target, which manipulates memory to create a SUID root shell. The module then uploads a Metasploit payload (default: cmd/unix/bind_netcat), marks it executable, and runs it as root via the newly created SUID shell. The exploit requires a local session on the target, a writable directory (default: /tmp), and gcc to be present. The module is weaponized, allowing for customizable payloads and automated cleanup. The only fingerprintable endpoints are the /usr/bin/rsh binary and the /tmp directory used for file operations. The code is structured as a standard Metasploit local exploit module, with options for target version, rsh path, and writable directory.
