CVE-2023-52331Network attack vector

Authenticated information disclosure via unvalidated resource URI

Published Jan 23, 2024 · Updated Jun 20, 2025

SSRF in modVulnerabilityProtect in Trend Micro Apex Central 2019 builds before 6570 allows remote authenticated users to read sensitive data. The module accesses resources from an attacker-controlled URI without properly validating its destination, causing the service account to contact internal or local services. Exploitation requires authentication and the ability to execute low-privileged code on the server; disclosed impact is data exposure with limited service-account actions.
