At a glance

CVE-2023-44988 is a medium-severity Missing Authentication for Critical Function vulnerability in the WP Custom Admin Interface WordPress plugin, affecting versions < 7.33. It carries a CVSS score of 4.3 (reachable over the network; low attack complexity). The root cause is a missing authorization check on a reachable function. The issue is fixed in version 7.33; sites on affected versions should update now. Disclosed September 2023, reported by Abdi Pranata.

Vulnerability Overview

The WP Custom Admin Interface plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the wp_custom_admin_interface_delete_transients function in versions up to, and including, 7.32. This makes it possible for authenticated attackers, with subscriber-level privileges and above, to delete plugin transients.

Technical Analysis

The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed, and no interaction from a victim user.

CWE-306: Missing Authentication for Critical Function

The product does not perform any authentication for functionality that requires a provable user identity or consumes a significant amount of resources.

Remediation

Update to version 7.33, or a newer patched version

How does WordSec protect against this?

Because it turns on account access, WordSec's login security is the relevant layer: role-based two-factor, captcha and brute-force limits raise the cost of getting the account this needs. None of that substitutes for the fix: WP Custom Admin Interface 7.33 closes this, and updating the plugin is the step that ends it.
