Vulnerability V-225226

If the application is a COTS product, this requirement is Not Applicable (NA). The infrastructure to enable Code Access Security (CAS) exists only in .NET Framework 2.x-4.x. The 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, run the following command: caspol.exe -all -lg Sample response: Microsoft (R) .NET Framework CasPol 4.0.30319.1 Security is ON Execution checking is ON Policy change prompt is ON Level = Machine Code Groups: 1.

At the least, this means it has been digitally signed with the private key associated with the public key recorded in the policy. The presence of the encryption key values in the StrongName field indicates the use of StrongNameMembershipCondition. If a Strong Name Membership Condition is assigned to a non-default Code Group the private key must be adequately protected by the software developer or the entity responsible for signing the assemblies. Ask the Systems Programmer how the private keys are protected. Private keys are simply values stored as strings of data. Keys can be stored in files on the file system or in a centralized data repository. Adequate protection methods include, but are not limited to: - utilizing centralized key management; - using strict file permissions to limit access; and - tying strong pass phrases to the key. If the private key used to sign the assembly is not adequately protected, this is a finding.

Ask the Systems Programmer how the private keys used to sign the assembly are protected. Private keys are simply values stored as strings of data. Keys can be stored in files on the file system or in a centralized data repository. Adequate protection methods include, but are not limited to: - utilizing centralized key management; - using strict file permissions to limit access; and - tying strong pass phrases to the key. The private key(s) used to sign the assembly must be protected. Utilize centralized key management or strict file permissions along with strong pass phrases and/or other well-established industry practices for managing and controlling access to private keys.
