< V9.24.10). A capture-replay flaw in the platform could have an impact to apps built with the platform, if certain preconditions are met that depend on the app's model and access control design. This could allow authenticated attackers to access or modify objects without proper authorization, or escalate privileges in the context of the vulnerable app.

Likely Mitigating Controls AI

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.

addresses: CWE-294

Allows detection of capture-replay attacks by showing the replayed logon's timestamp as the last logon.

addresses: CWE-294

Protects against replay of captured session tokens or credentials by requiring authenticated, fresh session channels.

addresses: CWE-294

Wireless link protections commonly incorporate replay protection, reducing the exploitability of capture-replay weaknesses.

addresses: CWE-294

Accurate synchronized time enables tight timestamp windows that directly limit capture-replay windows in authentication protocols.

Network monitoring may detect anomalous replays after the fact but does not prevent the design flaw.

PR.AA-03 partial match
blocks

Strong authentication methods can reduce replay risk but do not inherently address captured messages.

PR.AA-04 partial match
blocks

Protecting and verifying identity assertions prevents replay of captured authentication material.
