Executive Summary

This vulnerability is a heap-based buffer overflow in the Security Point (Windows) component of MaLion and MaLionCloud. It occurs when processing the Content-Length header in a request. A remote unauthenticated attacker can send a specially crafted request that triggers this overflow, potentially allowing them to execute arbitrary code with SYSTEM-level privileges on the affected system.

Impact Analysis

If exploited, this vulnerability can allow an attacker to execute arbitrary code with SYSTEM privileges remotely without authentication. This means the attacker could take full control of the affected system, potentially leading to data theft, system disruption, installation of malware, or further attacks within the network.
