Loading vulnerability…
The InPost Gallery WordPress plugin prior to version 2.1.4.1 insecurely uses PHP's extract() function when rendering HTML views. This allows attackers to manipulate variable extraction from user input, potentially forcing the inclusion of malicious files or URLs. As a result, attackers may be able to execute arbitrary code on the affected server.

This repository provides multiple scripts (in Python and Bash) to exploit CVE-2022-4063, a critical unauthenticated Local File Inclusion (LFI) to Remote Code Execution (RCE) vulnerability in the InPost Gallery WordPress plugin (versions < 2.1.4.1). The main exploit scripts are: - inpger.sh: A mass vulnerability checker that uses GNU Parallel to test multiple targets for the LFI/RCE vulnerability. It encodes a payload to read /etc/passwd and checks for the 'root:x:0' string in the response to determine vulnerability, logging results to vuln.txt and notvuln.txt. - single-exploiter.py and single-exploiter-beta.py: Python scripts that craft a complex PHP filter chain payload, base64-encode it, and send it to the vulnerable endpoint. These scripts can escalate from LFI to RCE by injecting a backdoor that allows arbitrary command execution via GET parameters. - single-exploiter-beta.sh: An interactive Bash script that allows the user to select between a standard LFI payload or a custom one, sending the payload to the vulnerable endpoint and decoding the response. The repository also includes sample output files (vuln.txt, notvuln.txt) and a README with usage instructions. The primary attack vector is network-based, targeting the /wp-admin/admin-ajax.php endpoint of WordPress sites running the vulnerable plugin. The exploit is operational, providing both detection and exploitation capabilities, including the ability to execute arbitrary commands on compromised systems.
