What attackers do: exploitation maps to Exploit Public-Facing Application (T1190). What defenders deploy: see the NIST 800-53 controls recommended below.

Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

CM-6 Configuration Settings good match

prevent

Establishes and enforces secure configuration settings for the OwnID plugin, ensuring the ownid_shared_secret is properly configured and not empty to prevent authentication bypass.

IA-5 Authenticator Management good match

prevent

Manages authenticators like the ownid_shared_secret used in JWT validation, requiring verification and sufficient strength to block bypass when the value is empty or invalid.

SI-2 Flaw Remediation good match

prevent

Identifies, reports, and corrects the specific authentication bypass flaw (CWE-288) in OwnID plugin versions up to 1.3.4 via timely patching.

The vulnerability is an authentication bypass in a public-facing WordPress plugin, allowing unauthenticated remote attackers to log in as any user including administrators, directly enabling exploitation of a public-facing application.

Confidence: HIGH · MITRE ATT&CK Enterprise v19.0

NVD Description

The OwnID Passwordless Login plugin for WordPress is vulnerable to Authentication Bypass in all versions up to, and including, 1.3.4. This is due to the plugin not properly checking if the ownid_shared_secret value is empty prior to authenticating a user…

via JWT. This makes it possible for unauthenticated attackers to log in as other users, including administrators, on instances where the plugin has not been fully configured yet.
