介绍

# Arbitrary File Upload Leads to RCE (CVE-2024-33438)
CubeCart <= 6.5.4 is vulnerable to an arbitrary file upload issue that leads to remote code execution (RCE). The vulnerability affects the application's file manager and its filters by allowing attackers to upload `.phar` files containing malicious code. CubeCart should be updated to 6.5.5 as it implements a security patch to fix this vulnerability.

For more details, please see the official announcement by CubeCart in the references.

## Exploit
An automated proof-of-concept (PoC) has been created, but this vulnerability can also be exploited manually by uploading a malicious `.phar` file via the file manager.
