What is known
The User Activity Log WordPress plugin before 1.6.5 does not correctly sanitise and escape several parameters before using it in a SQL statement as part of its exportation feature, allowing unauthenticated attackers to conduct SQL injection attacks.
Business impact
Successful exploitation of CVE-2023-3435, a critical vulnerability (CVSS 9.8) affecting user activity log, 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 user activity log 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.
