MITRE ATT&CK Enterprise Techniques

T1008 Fallback Channels Command And Control
Adversaries may use fallback or alternate communication channels if the primary channel is compromised or inaccessible in order to maintain reliable command and control and to avoid data transfer thresholds.
T1048 Exfiltration Over Alternative Protocol Exfiltration
Adversaries may steal data by exfiltrating it over a different protocol than that of the existing command and control channel.
T1048.003 Exfiltration Over Unencrypted Non-C2 Protocol Exfiltration
Adversaries may steal data by exfiltrating it over an un-encrypted network protocol other than that of the existing command and control channel.
T1190 Exploit Public-Facing Application Initial Access
Adversaries may attempt to exploit a weakness in an Internet-facing host or system to initially access a network.
T1211 Exploitation for Stealth Stealth
Adversaries may exploit vulnerabilities to evade detection by hiding activity, suppressing logging, or operating within trusted or unmonitored components.
T1542.002 Component Firmware Stealth
Adversaries may modify component firmware to persist on systems.

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-288 CWE-420

Authorizing remote access reduces the ability to bypass authentication via unauthorized alternate remote channels.

addresses: CWE-288

Users can identify logons via alternate paths or channels by reviewing the previous logon time.

addresses: CWE-288

Adaptive requirements can apply across access paths, reducing the ability to bypass authentication via alternate channels or paths.

addresses: CWE-288

Centralized IdPs close alternate authentication paths that enable bypass.

addresses: CWE-288

Enforces authentication for non-organizational users, making it harder to bypass via alternate paths or channels.

addresses: CWE-420

TSCM surveys detect and neutralize unprotected alternate channels introduced by surveillance equipment or modifications.

addresses: CWE-288

Requires authentication to occur exclusively over the isolated trusted path, directly preventing bypass via alternate or untrusted channels.

addresses: CWE-420

Removes or disables unprotected alternate I/O channels that could otherwise be used to bypass primary controls.

PR.AA-03 full match
prevents

Requiring authentication on every channel and path directly eliminates alternate-path bypasses.

PR.AA-05 mostly match
prevents

Enforcing authorizations and least privilege across all access vectors prevents unauthenticated alternate paths.

PR.DS-02 mostly match
prevents

Protecting all data-in-transit directly mitigates unequal channel protection though the control addresses broader transit scenarios.

PR.IR-01 mostly match
prevents

Protecting networks and environments from unauthorized logical access blocks bypass via undocumented channels.

DE.CM-01 partial match
prevents

Network monitoring can surface use of unprotected alternate channels but does not prevent the design flaw.

finds

Security testing can detect alternate-path bypasses but does not prevent them in production.

prevents

Access restrictions may cover primary paths but leave alternate channels unprotected unless explicitly extended.

degrades

Secure authentication control directly mitigates bypass by requiring strong, consistent authentication on all paths.

prevents

Access control policy directly addresses alternate authentication paths by requiring all channels to enforce authentication.

degrades

Authentication information management ensures credentials and mechanisms are consistently applied across all access paths.

prevents

Access rights provisioning and review prevent bypass via unmonitored or alternate channels.
