Vulnerability Details
This update resolves multiple vulnerabilities in Trend Micro OfficeScan:
1. A third-party component previously used for mapping displays was reported to be vulnerable to a XSS attack if exploited (VRTS-972).
2. A unauthenticated user could potentially attain remote code execution via a post-auth command injection (VRTS-337, 339).
Due to the seriousness of these and any vulnerabilities, customers are highly encouraged to update to the latest patches 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.
