MS10-083 - Important: Vulnerability in COM Validation in Windows Shell and WordPad Could Allow Remot

[News]

Bulletin Severity Rating:Important - This security update resolves a privately reported vulnerability in Microsoft Windows. The vulnerability could allow remote code execution if a user opens a specially crafted file using WordPad or selects or opens a shortcut file that is on a network or WebDAV share. An attacker who successfully exploited this vulnerability could gain the same user rights as the local user. Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights.

Summary of MS10-083:
The bulletin describes a vulnerability in COM validation within the Windows Shell and WordPad that could potentially lead to remote code execution. An attacker could exploit this vulnerability by tricking a user into opening a specially crafted file through:

• WordPad – Opening a compromised file could trigger remote code execution.
• Network or WebDAV shares – Selecting or opening a specially crafted shortcut file stored on external shares could also expose the system.

In either scenario, if the exploitation is successful, the attacker would gain the same user rights as the victim. This is particularly concerning if the user is operating with administrative privileges. Using a limited user account can mitigate risk exposure.
Key Considerations:

• Least Privilege Principle: Running as a non-administrative user wherever possible greatly limits the potential damage from an exploited vulnerability.
• Patch Management: Ensure that your systems are up-to-date with Microsoft’s security updates. This particular update resolved a privately reported vulnerability.
• Alternative Software: If you rely on WordPad for editing or viewing documents, consider exploring alternative applications that might offer enhanced security or are regularly updated.
• Verification of Information: As the original link appears to return a 404 error, it’s advisable to consult Microsoft’s official security advisory archive or reputable security news outlets for further details related to the advisory.
