This CP resolves the following in affected versions of Trend Micro Apex One:
- CVE-2019-18188: CVSSv3 8.2 – Affected versions of Apex One could be exploited by an attacker utilizing a command injection vulnerability to extract files from an arbitrary zip file to a specific folder on the Apex One server, which could potentially lead to remote code execution (RCE). The remote process execution is bound to the IUSR account, which has restricted permission and is unable to make major system changes. An attempted attack requires user authentication.
Customers are highly encouraged to update to the latest build as soon as possible.
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.
