Name of the Vulnerable Software and Affected Versions psPAS PowerShell module versions prior to 7.0.209

Description The psPAS PowerShell module does not enforce TLS 1.2 within the Get-PASSAMLResponse function during the SAML authentication process. This allows an unauthenticated attacker in a 'Man-in-the-Middle' position to potentially downgrade the TLS protocol to a deprecated version by manipulating the TLS handshake.
