Loading vulnerability…
CVE-2010-4170 is a privilege escalation vulnerability in the staprun runtime tool of SystemTap 1.3. The vulnerability arises because staprun does not properly clear the environment before executing modprobe, allowing a local attacker to set the MODPROBE_OPTIONS environment variable and specify a malicious configuration file. This can result in the execution of arbitrary code with elevated privileges.

This repository contains a single Metasploit module (Ruby file) that exploits a local privilege escalation vulnerability (CVE-2010-4170) in SystemTap's 'staprun' executable on Linux. The exploit leverages the fact that 'staprun' does not sanitize environment variables before invoking 'modprobe', allowing an attacker to specify a malicious configuration file via the MODPROBE_OPTIONS environment variable. This results in arbitrary command execution as root. The module uploads a payload (e.g., a root shell or meterpreter) and a crafted config file to a writable directory (default: /tmp), then triggers the vulnerability to execute the payload as root. The exploit is operational and provides root access if successful. The main fingerprintable endpoints are the path to the vulnerable 'staprun' binary and the writable directory used for payload deployment. The module is well-structured, includes checks for the presence and permissions of 'staprun', and is designed for use within the Metasploit framework.
