Exploit:JS/Mult.BM
Exploit:Win32/CVE-2009-1537

Vulnerability details

Advisory: SB2009052801 - Remote code execution in Microsoft DirectX

Vulnerable component: Microsoft DirectX

CVE-ID: CVE-2009-1537

CWE-ID: CWE-626 - Null Byte Interaction Error (Poison Null Byte)

Description:

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The weakness exists due to NULL byte error in DirectX. A remote attacker can create a specially crafted QuickTime media file, trick the victim into opening it, trigger memory corruption and execute arbitrary code on the target system with privileges of the current user.

Successful exploitation of the vulnerability results in arbitrary code execution on the vulnerable system.

Note: the vulnerability was being actively exploited.

About zero-day vulnerabilities

Zero-day vulnerability is an undisclosed vulnerability in software that hackers can exploit to compromise computer programs, gain unauthorized access to sensitive data, penetrate networks, etc. We consider vulnerability a zero-day when there is no solution provided from software vendor and the vulnerability is being actively exploited by malicious actors.

Zero-day candidate is a potential zero-day vulnerability in software which might have been used in targeted attacks, however there is no evidence to support this suggestion.
