MS08-021 Exploit Activity Increasing

Last week we discussed the fact that Microsoft credited three different researchers for reported CVE-2008-1087 during our monthly Patch Tuesday podcast. The fact that several independent researchers reported the issue suggested that others may not be far behind. This CVE pertains to the Microsoft Graphics Rendering Engine, which has a history of exploitation. In fact, McAfee’s Exploit-WMF detection for MS06-001 exploits was one of the top reported detections around the time that a patch was released. An exploit toolkit was released prior to the patch, which helped contribute to the number of exploits floating around. History may be repeating itself, though out of sequence.
Last Friday the first MS08-021 exploit was discovered in the field, three days after the issue was patched; and though it was not widespread, the discovery of the exploit did highlight the fact that attackers were actively working with exploit code. Today a basic exploit toolkit was posted publicly; and while this new toolkit is primitive, it may very well lead to “one-ups-manship” and the distribution of a more powerful tool.
Given the fact that a patch was released prior to this recent exploit activity it is unlikely that MS08-021 attacks will reach the level of MS06-001 attacks. However, there are still many many vulnerable systems out there, and we’ve seen prevalent exploits that have lasted for years after the issue was patched.
