T1010 Application Window Discovery Discovery
Adversaries may attempt to get a listing of open application windows.
T1011.001 Exfiltration Over Bluetooth Exfiltration
Adversaries may attempt to exfiltrate data over Bluetooth rather than the command and control channel.
T1012 Query Registry Discovery
Adversaries may interact with the Windows Registry to gather information about the system, configuration, and installed software.
T1016 System Network Configuration Discovery Discovery
Adversaries may look for details about the network configuration and settings, such as IP and/or MAC addresses, of systems they access or through information discovery of remote systems.

Mitigating Controls

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-425

Forcing a decision on every access request, including direct ones, reduces the exploitability of forced browsing by ensuring no unchecked access paths.

addresses: CWE-425

Forces all accesses through the reference monitor, preventing direct or forced requests that bypass checks.

addresses: CWE-425

Enforcing access for all logical requests prevents unauthorized direct access to protected resources.

addresses: CWE-425

Displaying the notification before further access on public systems prevents direct resource requests from bypassing the required system use terms and consent.

addresses: CWE-425

Decoy endpoints catch forced browsing and direct requests, deflecting attackers from legitimate resources while enabling analysis.

addresses: CWE-425

Blocks unauthorized direct requests or forced browsing by denying input access to non-authorized actors.

PR.AA-05 partial match
blocks

Directly requires policy-driven definition, enforcement, and review of authorizations on resources such as URLs.

PR.IR-01 partial match

Protects environments from unauthorized logical access, which includes preventing direct requests to restricted paths.

removes
blocks

A.5.15 directly requires defining/implementing access control rules, authorization, need-to-know, and restrictions that enforce appropriate access on all URLs/resources, which stops forced browsing exploitation even if the flaw remains; remainder is bounded to non-authorization cases like path traversal or CSRF (per AC-3 anchor).
