The CA API Gateway providing user authentication intermediary services must implement replay-resistant authentication mechanisms for network access to non-privileged accounts.
Medium Severity
<VulnDiscussion>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 non-privileged account is any account with the authorizations of a non-privileged user. Privileged roles are organization-defined roles assigned to individuals that allow those individuals to perform certain security-relevant functions that ordinary users are not authorized to perform. Security-relevant roles include key management, account management, network and system administration, database administration, and web administration. Techniques used to address this include protocols using nonces (e.g., numbers generated for a specific one-time use) or challenges (e.g., TLS). Additional techniques include time-synchronous or challenge-response one-time authenticators. The CA API Gateway registered services requiring replay-resistance must include an out-of-the-box "Protect Against Message Replay" Assertion that will assist with preventing the replay of authenticated sessions accessing network resources.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
