CVE-2023-21839

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.

Penetration testing supplies malicious serialized objects, detecting unsafe deserialization and supporting corrective actions.

Managing identities and credentials is a prerequisite for authentication but does not itself enforce it on critical functions.

Defining and enforcing authorizations assumes prior authentication and therefore only partially mitigates the absence of authentication.

Protecting networks from unauthorized access can be undermined by missing authentication but does not address the root authentication gap.

Mandating authentication requirements for critical functions at the requirements-gathering stage ensures that essential operations are not left unprotected by missing login or verification mechanisms.

Mandating authentication for network services and critical functions stops attackers from invoking sensitive operations without credentials, closing gaps where authentication is absent for important capabilities.

Security engineering principles insist on authentication and authorization for every critical function, eliminating entry points that lack any access control mechanism.

Requiring vetted libraries, regular updates and SAST before release reduces the likelihood that deserialization logic will accept and act on attacker-controlled serialized objects.
