The container platform must implement replay-resistant authentication mechanisms for network access to nonprivileged accounts.

STIG ID: SRG-APP-000157-CTR-000385  |  SRG: SRG-APP-000157 |  Severity: medium |  CCI: CCI-001941 |  Vulnerability Id: V-233085

Vulnerability Discussion

A replay attack may enable an unauthorized user to gain access to the application. Authentication sessions between the authenticator and the application validating the user credentials must not be vulnerable to a replay attack.

An authentication process resists replay attacks if it is impractical to achieve a successful authentication by recording and replaying a previous authentication message.

A nonprivileged account is any operating system account with authorizations of a nonprivileged user.

Techniques used to address this include protocols using nonces (e.g., numbers generated for a specific one-time use) or challenges (e.g., TLS, WS_Security). Additional techniques include time-synchronous or challenge-response one-time authenticators.

Check

Review the container platform configuration to determine if the container platform is configured to provide replay-resistant authentication mechanisms for network access to nonprivileged accounts.

If the container platform is not configured to provide replay-resistant authentication mechanisms for network access to nonprivileged accounts, this is a finding.

Fix

Configure the container platform to provide replay-resistant authentication mechanisms for network access to nonprivileged accounts.
