CWE-757

Selection of Less-Secure Algorithm During Negotiation ('Algorithm Downgrade')

A protocol or its implementation supports interaction between multiple actors and allows those actors to negotiate which algorithm should be used as a protection mechanism such as encryption or authentication, but it does not select the strongest algorithm that is available to both parties.

  • CWE-757 - Selection of Less-Secure Algorithm During Negotiation ('Algorithm Downgrade')
Summary
psPAS PowerShell module does not explicitly enforce TLS 1.2 within the 'Get-PASSAMLResponse' function during the SAML authentication process. An unauthenticated attacker in a 'Man-in-the-Middle' position could manipulate the TLS handshake and downgrade TLS to a deprecated protocol. Fixed in 7.0.209.

CAPEC-220: Client-Server Protocol Manipulation

An adversary takes advantage of weaknesses in the protocol by which a client and server are communicating to perform unexpected actions. Communication protocols are necessary to transfer messages between client and server applications. Moreover, different protocols may be used for different types of interactions.

CAPEC-606: Weakening of Cellular Encryption

An attacker, with control of a Cellular Rogue Base Station or through cooperation with a Malicious Mobile Network Operator can force the mobile device (e.g., the retransmission device) to use no encryption (A5/0 mode) or to use easily breakable encryption (A5/1 or A5/2 mode).

CAPEC-620: Drop Encryption Level

An attacker forces the encryption level to be lowered, thus enabling a successful attack against the encrypted data.
