        Full System Compromise: How a Single Field in the Windows Heap Leads to Arbitrary Read/Write and Total Control     By CyberDudeBivash • September 29, 2025, 3:49 PM IST • Security Research Analysis   In the intricate art of exploit development, the ultimate goal is to turn a small, seemingly insignificant bug into a weapon of absolute power. The holy grail is the creation of an "arbitrary read/write primitive"—the ability to read and write any data, anywhere in a target application's memory. Achieve this, and all other defenses crumble. Today, we are dissecting a sophisticated and elegant technique that does exactly that. This is not a specific CVE, but a deep-dive into a powerful exploitation methodology. We will explore how a clever attacker can leverage a simple, limited buffer overflow to corrupt one single, overlooked metadata field in the Windows Heap. By manipulating this one field, they can trick the Heap Manager itself into...
