CVE-2016-1223
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedDirectory traversal vulnerability in Trend Micro Office Scan 11.0, Worry-Free Business Security Service 5.x, and Worry-Free Business Security 9.0 allows remote attackers to read arbitrary files via unspecified vectors.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceDirectory traversal vulnerability in Trend Micro enterprise security products allows remote unauthenticated attackers to access files outside the intended directory by manipulating path traversal sequences (e.g., using '../' sequences) in unspecified input vectors, leading to information disclosure.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify installed Trend Micro productCheck the system for installed Trend Micro enterprise security software by reviewing installed programs in Control Panel, checking services named 'Trend Micro', or looking for Trend Micro program directories (typically in C:\Program Files\Trend Micro\ or C:\Program Files (x86)\Trend Micro\)Affected if Any of the following products are installed: Officescan, Worry Free Business Security, or Worry Free Business Security Services
-
Determine the installed version numberOpen the Trend Micro product console or main GUI, which typically displays the version information. Alternatively, check the program's properties in Add/Remove Programs, or look for version info in the program's installation directoryAffected if The version displayed is exactly 11.0 for Officescan, 9.0 for Worry Free Business Security, or 5.0 for Worry Free Business Security Services
-
Verify the web management interface is accessibleCheck if the Trend Micro web console is accessible on the default ports (typically port 8080, 4343, or 443 for HTTPS). Attempt to access the login page via browser. Also verify the corresponding Windows service is runningAffected if The web management interface is exposed and reachable on the network
-
Check network exposure of the serviceUse netstat or similar tools to determine if the Trend Micro service is bound to all interfaces (0.0.0.0) or only localhost. Review firewall rules to see if the management port is open to untrusted networksAffected if The service is listening on external interfaces and accessible from untrusted networks
A system is affected if it is running exactly version 11.0 of Officescan, version 9.0 of Worry Free Business Security, or version 5.0 of Worry Free Business Security Services, and the web management interface is network-accessible.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataApply vendor patches from Trend Micro for the affected product versions. As an immediate workaround, restrict network access to the affected service and implement strict input validation on file path parameters.
