CVE-2023-3404: profilegrid vulnerability

What is known

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.

Business impact

Successful exploitation of CVE-2023-3404, a medium vulnerability (CVSS 4.9) affecting profilegrid, may affect the confidentiality, integrity or availability of the vulnerable environment. The exact impact depends on the installed version, exposed interfaces and deployment configuration.

Recommended administrator action

Confirm whether profilegrid is present and compare installed versions with the vendor advisory and NVD record. Apply the vendor patch or documented mitigation; until remediation is complete, reduce exposure of affected interfaces, review relevant logs and monitor for indicators of exploitation. DataHouse can support version verification, managed patching, network exposure reduction, log review and backup validation for dedicated, cloud and colocated environments.
