CVE-2024-4611: apppresser vulnerability

What is known

The AppPresser plugin for WordPress is vulnerable to improper missing encryption exception handling on the 'decrypt_value' and on the 'doCookieAuth' functions in all versions up to, and including, 4.3.2. This makes it possible for unauthenticated attackers to log in as any existing user on the site, such as an administrator, if they previously used the login via the plugin API. This can only be exploited if the 'openssl' php extension is not loaded on the server.

Business impact

Successful exploitation of CVE-2024-4611, a high vulnerability (CVSS 8.1) affecting apppresser, 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 apppresser 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.
