CVE Catalog

CVE-2005-4360

High
Published: Translated: NVD NIST

Summary

The URL parser in Microsoft Internet Information Services (IIS) 5.1 on Windows XP Professional SP2 allows remote attackers to execute arbitrary code via multiple requests to '.dll' followed by arguments such as '~0' through '~9', which causes ntdll.dll to produce a return value that is not correctly handled by IIS, potentially leading to code execution rather than just a denial of service as originally believed.

Risk Assessment

The risk for the organization includes the possibility of remote takeover of the IIS server, which could lead to data theft, malware installation, or further attacks on the internal network.

Recommendation

It is recommended to immediately apply the security update from Microsoft for IIS 5.1 or upgrade to a newer, supported version of Windows that is not vulnerable to this flaw.

Original NVD description (English source)

The URL parser in Microsoft Internet Information Services (IIS) 5.1 on Windows XP Professional SP2 allows remote attackers to execute arbitrary code via multiple requests to ".dll" followed by arguments such as "~0" through "~9", which causes ntdll.dll to produce a return value that is not correctly handled by IIS, as demonstrated using "/_vti_bin/.dll/*/~0". NOTE: the consequence was originally believed to be only a denial of service (application crash and reboot).
