What is CVE-2019-12169?

ATutor version 2.2.4 is susceptible to vulnerabilities that allow attackers to perform arbitrary file uploads and exploit directory traversal. This can lead to remote code execution by utilizing a specially crafted ZIP archive to manipulate file paths in critical components like language_import.php and the patcher module. As a result, unauthorized users may gain access to the system and execute harmful code, posing serious risks to the integrity and security of the application.

Exploit Proof of Concept (PoC)

PoC code is written by security researchers to demonstrate the vulnerability can be exploited. PoC code is also a key component for weaponization which could lead to ransomware.
