## From the sources

Improper validation of some components used by the rollback mechanism in Trend Micro Apex One and Trend Micro Apex One as a Service clients could allow a Apex One server administrator to instruct affected clients to download an unverified rollback package, which could lead to remote code execution. Please note: an attacker must first obtain Apex One server administration console access in order to exploit this vulnerability.
