Detailed Description |
| Business Impact: |
This issue is a remote code execution vulnerability in Microsoft Internet Information Services 5.1. This vulnerability was first disclosed as a denial-of-service issue in 2005, and a DOS proof-of-concept has been publicly available since then. Recently, new information has come to light indicating that this vulnerability can be leveraged to obtain remote code execution. Although the exploit is difficult to reproduce, we may see public exploitation in the weeks after disclosure due to the amount of information that is already available and the novelty of the attack methodology. As web servers are critical infrastructure, IBM ISS X-Force advises administrators with vulnerable IIS servers to treat this issue with the highest priority. |
