Summary

CVE-2024-0701 is a medium-severity Client-Side Enforcement of Server-Side Security (CWE-602) vulnerability in Userproplugin Userpro. Its CVSS base score is 5.3 (Medium).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 45th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified map to AC-25 (Reference Monitor) and AC-3 (Access Enforcement) — see the control section below for these in your framework.

Vulnerability Data

The UserPro plugin for WordPress is vulnerable to Security Feature Bypass in all versions up to, and including, 5.1.6. This is due to the use of client-side restrictions to enforce the 'Disabled registration' Membership feature within the plugin's General settings.…

Mitigating Controls (NIST 800-53 r5) AI

AC-25 Reference Monitor good match

Requires a tamper-proof, always-invoked reference monitor that cannot be bypassed by client-side logic.

AC-3 Access Enforcement good match

Enforces all access decisions on the server according to policy rather than trusting client-supplied enforcement.

AC-4 Information Flow Enforcement good match

Enforces information-flow rules at the server boundary instead of delegating them to the client.

SC-7 Boundary Protection partial match

Monitors and controls all external and key internal interfaces so that server-side policy cannot be off-loaded to clients.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.

PR.PS-06 mostly match
prevents

Secure SDLC practices directly prevent design flaws that place server security enforcement on the client.

PR.AA-05 partial match
prevents

Proper policy-based enforcement of authorizations implies server-side controls rather than client-only checks.

A.8.27 Secure system architecture and engineering principles mostly match
prevents

Secure architecture principles discourage client-side trust but do not directly address this weakness.

A.8.29 Security testing in development and acceptance mostly match
finds

Security testing can detect client-side enforcement but is not the primary mitigation.

A.8.3 Information access restriction mostly match
prevents

Information access restriction is undermined when the client is trusted to enforce it.

A.8.25 Secure development life cycle partial match
prevents

Secure development lifecycle mandates server-side validation and prevents reliance on client enforcement.

A.8.26 Application security requirements partial match
prevents

Application security requirements explicitly call for server-side enforcement of security mechanisms.

A.8.28 Secure coding partial match
prevents

Secure coding standards require server-side checks and reject client-only enforcement.
