Microsoft Windows Application Compatibility Cache Elevation of Privilege Vulnerability (MS15-001)
- Severity
- Urgent 5
- Qualys ID
- 91005
- Vendor Reference
- MS15-001
- CVE Reference
- CVE-2015-0002
- CVSS Scores
- Base 7.2 / Temporal 6
- Description
-
An elevation of privilege vulnerability exists in how the Microsoft Windows Application Compatibility Infrastructure (AppCompat) improperly checks the authorization of the caller's impersonation token. An attacker could attempt to exploit this to run a privileged application.
Microsoft has released a security update that addresses the vulnerability by changing how Windows Application Compatibility Infrastructure processes impersonation token usage.
This security update is rated Important for all supported editions of Windows 7, Windows Server 2008 R2, Windows 8, Windows Server 2012, Windows RT, Windows 8.1, Windows Server 2012 R2, and Windows RT 8.1.
Note: Previously, this was a zero day reported on Windows 8.1 systems. Refer to Elevation of Privilege in ahcache.sys/NtApphelpCacheControl for more details.
- Consequence
- The vulnerability could allow elevation of privilege if an attacker logs on to a system and runs a specially crafted application. An authenticated attacker who successfully exploited this vulnerability could bypass existing permission checks that are performed during cache modification in the Microsoft Windows Application Compatibility component and execute arbitrary code with elevated privileges.
- Solution
-
Refer to Microsoft Security Bulletin MS15-001 for details.

Microsoft Windows Network Location Awareness Service Security Bypass Vulnerability (MS15-005)
- Severity
- Critical 4
- Qualys ID
- 91007
- Vendor Reference
- MS15-005
- CVE Reference
- CVE-2015-0006
- CVSS Scores
- Base 6.1 / Temporal 4.5
- Description
-
A security feature bypass vulnerability exists in the Network Location Awareness (NLA) service that could unintentionally relax the firewall policy and/or configuration of certain services. This could increase the surface exposed to an attacker. The vulnerability is caused when the NLA service fails to properly validate whether a domain-connected computer is connected to the domain or to an untrusted network.
Microsoft released an update that addresses the vulnerability by forcing mutual authentication via Kerberos. The vulnerability could allow security feature bypass by unintentionally relaxing the firewall policy and/or configuration of certain services when an attacker on the same network as the victim spoofs responses to DNS and LDAP traffic initiated by the victim.
This security update is rated Important for all supported editions of Windows 2003, Windows Vista, Windows Server 2008, Windows 7, Windows Server 2008 R2, Windows 8, Windows Server 2012, Windows 8.1 and Windows Server 2012 R2.
- Consequence
- Successful exploitation of this vulnerability requires that an attacker be connected to the same network as the victim's computer, and that the attacker spoof responses to DNS and LDAP traffic initiated by the victim. The vulnerability could allow an attacker to apply a domain profile to a computer connected to an untrusted network. Client computers connected to untrusted networks are primarily at risk from this vulnerability.
- Solution
-
Refer to MS15-005 for further information.
Note : Windows Server 2003 is listed as an affected product, however; Microsoft is not issuing an update for it because the comprehensive architectural changes required would jeopardize system stability and cause application compatibility problems. It is advisable to upgrade to a later operating system if you are running Windows Server 2003.
