Vulnerability details

Microsoft has released 2 security bulletins to fix newly discovered flaws in their software. Qualys has released the following checks for these new vulnerabilities:

• Windows Services DACLs Privilege Escalation (MS06-011)

  Severity

  Serious 3

  Qualys ID

  90293

  Vendor Reference

  MS06-011

  CVE Reference

  CVE-2006-0023

  CVSS Scores

  Base 4.3 / Temporal 3.7

  Description

  Security update MS06-011 is not installed.

  A privilege escalation vulnerability exists on Windows XP Service Pack 1 on the identified Windows services where the permissions are set by default to a level that may allow a low-privileged user to change properties associated with the service. On Windows 2003 permissions on the identified services are set to a level that may allow a user that belongs to the network configuration operators group to change properties associated with the service. Only members of the Network Configuration Operators group on the targeted machine can remotely attack Windows Server 2003, and this group contains no users by default. The vulnerability could allow a user with valid logon credentials to take complete control of the system on Microsoft Windows XP Service Pack 1.

  Proof of concept code exists that attempts to exploit overly permissive access controls on default services of Windows XP Service Pack 1 and Windows Server 2003.

  Microsoft has rated this vulnerability as Important.

  Consequence

  If successful, an attacker who has low user privileges could gain privilege escalation. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.
