At a glance

CVE-2023-3404 is a medium-severity Use of Hard-coded Cryptographic Key vulnerability in the ProfileGrid WordPress plugin, affecting versions <= 5.5.0. It carries a CVSS score of 4.9 (reachable over the network; low attack complexity; high confidentiality impact). The issue is fixed in version 5.5.1; sites on affected versions should update now. Disclosed July 2023, reported by István Márton.

Vulnerability Overview

The ProfileGrid plugin for WordPress is vulnerable to unauthorized decryption of private information in versions up to, and including, 5.5.0. This is due to the passphrase and iv being hardcoded in the 'pm_encrypt_decrypt_pass' function and used across all sites running the plugin. This makes it possible for authenticated attackers, with administrator-level permissions or above to decrypt and view users' passwords. If combined with another vulnerability, this can potentially grant lower-privileged users access to users' passwords.

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. A successful exploit has high impact on confidentiality.

CWE-321: Use of Hard-coded Cryptographic Key

The product uses a hard-coded, unchangeable cryptographic key.

Remediation

Update to version 5.5.1, or a newer patched version

How does WordSec protect against this?

The fix is the thing that ends this: ProfileGrid 5.5.1 closes this, and updating the plugin is the step that ends it.
