Loading vulnerability…
PrestaShop versions 1.6.x before 1.6.1.23 and 1.7.x before 1.7.4.4 are vulnerable to an arbitrary file upload vulnerability. Remote attackers can exploit this flaw to upload malicious files, which can then be executed on the server, leading to remote code execution. The vulnerability is due to insufficient validation of uploaded files, allowing attackers to bypass restrictions and upload executable code.

This repository provides a working exploit for CVE-2018-19126, a remote code execution vulnerability in PrestaShop Back Office. The exploit chains multiple vulnerabilities, including a directory rename/delete flaw (CVE-2018-19125) and a deserialization bug via the PHP phar wrapper, to achieve RCE. The main exploit script, 'exploit.php', is a standalone PHP script that automates the attack steps: authenticating to the PrestaShop Back Office, uploading a malicious phar file (crafted with a Monolog gadget chain), renaming the upload directory to bypass security checks, and finally triggering the deserialization via a crafted HTTP POST request. The script requires valid Back Office credentials and a vulnerable PrestaShop version. The payload is customizable, allowing execution of arbitrary system commands. The repository is structured simply, with a license, a detailed README explaining the vulnerability and exploitation steps, and the exploit script itself. The attack is performed over HTTP(S) endpoints exposed by the PrestaShop Back Office file manager.
