Vulnerability V-225225

The infrastructure to enable Code Access Security (CAS) exists only in .NET Framework 2.x-4.x. This requirement is Not Applicable (NA) for .NET Framework greater than 4.x. (Note: The infrastructure is deprecated and is not receiving servicing or security fixes.) Caspol.exe is a Microsoft tool used for working with .Net policy. Use caspol.exe to list the code groups and any publisher membership conditions. The location of the caspol utility is dependent upon the system architecture of the system running .Net. For 32 bit systems, caspol.exe is located at %SYSTEMROOT%\Microsoft.NET\Framework\v4.0.30319. For 64 bit systems, caspol.exe is located at %SYSTEMROOT%\Microsoft.NET\Framework64\v4.0.30319. Example: cd %SYSTEMROOT%\Microsoft.NET\Framework\v4.0.30319 To check code groups for the machine, run the following command: caspol.exe -m -lg Sample Results: Microsoft (R) .NET Framework CasPol 4.0.30319.1 Copyright (c) Microsoft Corporation.

If the Publisher Membership Condition is used on a nondefault Code Group and the use of that publisher's certificate is not documented and approved by the ISSO, this is a finding.

Trust must be established when utilizing Publishers Membership Condition. All publisher's certificates must have documented approvals from the ISSO.
