CVE-2009-1122

Name of the Vulnerable Software and Affected Versions Microsoft Internet Information Services (IIS) 5.0 on Windows 2000 SP4

Description The issue concerns the WebDAV extension in Microsoft Internet Information Services (IIS) 5.0, which fails to properly decode URLs. This allows remote attackers to bypass authentication and potentially read or create files by sending a crafted HTTP request.

Recommendations For Microsoft Internet Information Services (IIS) 5.0 on Windows 2000 SP4, consider disabling the WebDAV extension as a temporary workaround until a patch is available. Restrict access to sensitive files and directories to minimize the risk of exploitation.
