Authenticated remote code execution via command injection

Published May 27, 2020 · Updated Aug 4, 2024

Remote code execution in Trend Micro InterScan Web Security Virtual Appliance 6.5 allows remote authenticated users to execute arbitrary commands. The advisory identifies a command-injection flaw but does not disclose the affected request, parameter, or component that passes attacker input to a command interpreter. Exploitation requires authentication to the appliance's remotely reachable interface; successful attacks can run commands with the appliance's privileges and compromise confidentiality, integrity, and availability.
