Microsoft Windows access controls may be improperly configured potentially allowing a local attacker to gain elevated privileges on a vulnerable system.
Microsoft Windows provides numerous, fine grained permissions and privileges to control access to Windows components, such as services, files, and registry entries.
Recent research has uncovered insecure configurations within user accounts and groups on Microsoft Windows systems. These configurations may allow local attackers to gain access to, and manipulate system resources. The researchers have developed a model that analyzes permissions to expose privilege escalation vulnerabilities. The research focused on three particular components of the Windows architecture:
A local user with valid login credentials may be able gain elevated privileges on a vulnerable Windows system.
These issues are corrected in Service Pack 2 for Microsoft Windows XP and Service Pack 1 for Microsoft Windows Server 2003. In addition, Microsoft Security Advisory 914457 and Microsoft Security Bulletin MS06-011 contain numerous workarounds to mitigate these vulnerabilities.
These vulnerabilities were reported by Sudhakar Govindavajhala and Andrew W. Appel.
