Sources and claim methodology

Upstream source description

Trend Micro OfficeScan versions 11.0 and XG (12.0) could be exploited by an attacker utilizing a directory traversal vulnerability to extract files from an arbitrary zip file to a specific folder on the OfficeScan server, which could potentially lead to remote code execution (RCE). The remote process execution is bound to a web service account, which depending on the web platform used may have restricted permissions. An attempted attack requires user authentication.
