Trend Micro OfficeScan Directory Traversal Vulnerability
Does this matter?
Known to be exploited in the wild (CISA KEV, CISA remediation deadline 3 May 2022). Treat as an emergency change: patch or isolate now, then hunt for prior compromise.
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.
