Vulnerability Details

This CP resolves a vulnerability in Trend Micro Application Endpoint Control 2.0 that, if exploited, could allow an attacker that has previously obtained a guest account to directly access the FileDrop servlet in the policy manager to upload files with malicious file names allowing directory traversal and policy uploads.

Due to the seriousness of this or any vulnerability, customers are highly encouraged to update to the latest build as soon as possible.

Mitigating Factors

Exploiting these type of vulnerabilities generally require that an attacker has access (physical or remote) to a vulnerable machine. In addition to timely application of patches and updated solutions, customers are also advised to review remote access to critical systems and ensure policies and perimeter security is up-to-date.

However, even though an exploit may require several specific conditions to be met, Trend Micro strongly encourages customers to update to the latest builds as soon as possible.
