| Detailed Description |
The 'Microsoft Transaction Server' registry key is writable by users who are not in the Administrators group.
Microsoft Transaction Server (MTS) is the mechanism used by Microsoft Windows NT to handle transactions or MTS packages which are series of software modules that form a transaction. The lenient permissions on the Microsoft Transaction Server Package Administration key, HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Transaction Server\Packages, could allow an attacker to add themselves as an MTS manager. A local attacker can use this vulnerability to delete, add, or execute MTS packages on a system under the security context of their account. This vulnerability could be exploited remotely if the Winreg key was enabled to allow remote access to the registry (Winreg is disabled by default in Windows NT Server and enabled by default in Windows NT Workstation).
MTS is not installed by default on Windows NT 4.0.
* Note: This check requires an account with Guest or upper privileges which can access the registry of the remote host to scan. Absence of these condition will result in the check not being performed and a False Negative for all vulnerable hosts.
