What is CVE-2008-20001?

The activePDF WebGrabber version 3.8.2.0 contains a stack-based buffer overflow vulnerability within the GetStatus() method of the APWebGrb.ocx ActiveX control. This issue arises when an attacker sends an excessively long string to this method, potentially allowing arbitrary code execution in the context of the process running the affected control. Although this ActiveX control is not marked safe for scripting, it can still be exploited if executed within crafted HTML content in Internet Explorer, particularly under configurations with lenient security settings.

Affected Version(s)

WebGrabber * <= 3.8.2.0

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.
