Likely Mitigating ControlsAI
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.
Requires established identification and authentication to unlock, mitigating missing authentication for continued system access.
Requiring identification and rationale for actions allowed without authentication ensures critical functions are not left unprotected by forcing review of authentication requirements.
Authorizing mobile device connections to organizational systems ensures authentication is performed for this critical access function.
Guarantees critical functions are protected by mandatory invocation of the access control mechanism.
Auditing sessions makes it possible to detect access to critical functions without required authentication.
The assessment process confirms authentication is present and effective for critical functions, preventing exploitation from missing authentication.
Certification assesses that critical functions have required authentication controls in place.
Disabling non-essential functions and services eliminates the need to secure them, reducing exposure from missing authentication on unnecessary components.
MITRE ATT&CK Enterprise TechniquesAI
Why these techniques?
Missing authentication checks (CWE-306) in Struts2 web actions directly enable remote exploitation of a public-facing application without credentials.
NVD Description
FACTION is a PenTesting Report Generation and Collaboration Framework. Prior to 1.8.3, AccessControlInterceptor, the authentication gate for all Struts2 actions, unconditionally calls invocation.invoke() without checking for a valid session. Four action methods in BoilerPlateConfig perform no local session check either,…
