Windows Access Control Demystified.

Hello everybody, We have constructed a logical model of Windows XP access control, in a declarative but executable (Datalog) format. We have built a scanner that reads access-control configuration information from the Windows registry, file system, and service control manager database, and feeds raw configuration data to the model. Therefore we can reason about such things as the existence of privilege-escalation attacks, and indeed we have found several user-to-administrator vulnerabilities caused by misconfigurations of the access-control lists of commercial software from several major vendors. We propose tools such as ours as a vehicle for software developers and system administrators to model and debug the complex interactions of access control on installations under Windows. The full version of the paper can be found at: http://www.cs.princeton.edu/~sudhakar/papers/winval.pdfAll the vendors and CERT are aware of this paper. The bugs are *not* remotely exploitable. The CERT id is VU#953860.
