Detailsinfo

A vulnerability, which was classified as critical, has been found in Microsoft Windows Server 2003/XP (Operating System). Affected by this issue is some unknown processing of the component Service Handler. The manipulation of the argument SERVICE_CHANGE_CONFIG with an unknown input leads to a access control vulnerability. Using CWE to declare the problem leads to CWE-264. Impacted is confidentiality, integrity, and availability. CVE summarizes:

Microsoft Windows XP SP1 and SP2 before August 2004, and possibly other operating systems and versions, uses insecure default ACLs that allow the Authenticated Users group to gain privileges by modifying critical configuration information for the (1) Simple Service Discovery Protocol (SSDP), (2) Universal Plug and Play Device Host (UPnP), (3) NetBT, (4) SCardSvr, (5) DHCP, and (6) DnsCache services, aka "Permissive Windows Services DACLs." NOTE: the NetBT, SCardSvr, DHCP, DnsCache already require privileged access to exploit.

The weakness was released 02/08/2006 by Sudhakar Govindavajhala and Andrew W. Appel as confirmed bulletin (Technet). The advisory is shared for download at microsoft.com. This vulnerability is handled as CVE-2006-0023 since 11/30/2005. The exploitation is known to be easy. Access to the local network is required for this attack to succeed. Required for exploitation is a simple authentication. Technical details as well as a exploit are known. The MITRE ATT&CK project declares the attack technique as T1068.

It is declared as highly functional. The vulnerability scanner Nessus provides a plugin with the ID 21077 (MS06-011: Permissive Windows Services DACLs Could Allow Elevation of Privilege (914798)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Windows : Microsoft Bulletins and running in the context l. The commercial vulnerability scanner Qualys is able to test this issue with plugin 90293 (Windows Services DACLs Privilege Escalation (MS06-011)).

Applying a patch is able to eliminate this problem. The bugfix is ready for download at windowsupdate.microsoft.com. A possible mitigation has been published 2 months after the disclosure of the vulnerability.

The vulnerability is also documented in the databases at X-Force (24463), Tenable (21077), SecurityFocus (BID 16484†), OSVDB (23047†) and Secunia (SA19313†). Once again VulDB remains the best source for vulnerability data.
