CVE-2016-7802
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 Cybozu Garoon 3.0.0 to 4.2.2 allows remote authenticated 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 · high confidenceA directory traversal vulnerability exists in Cybozu Garoon versions 3.0.0 through 4.2.2. The flaw allows remote authenticated attackers to access the filesystem and read arbitrary files on the host system via unspecified vectors, potentially exposing sensitive system or application data.

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.
-
Confirm Cybozu Garoon installationLocate Garoon installation directories or running services on the system. Check for typical Garoon process names or web application artifacts.Affected if Cybozu Garoon software is found on the system
-
Identify installed Garoon versionAccess the Garoon administration interface or check version information files within the Garoon installation directory. Compare the discovered version against the affected range.Affected if The installed version is 3.0.0 through 4.2.2, or any version between 3.0.0 and 3.5.3 specifically
-
Determine if remote authenticated access is possibleVerify whether the Garoon web interface is exposed to network access and whether user authentication mechanisms are enabled. Check network configuration for open ports serving Garoon.Affected if Garoon is network-accessible and accepts authenticated user sessions
-
Review access logs for suspicious file access patternsExamine Garoon application logs and web server logs for unusual traversal patterns such as ../../ sequences or access to system files outside the expected document root.Affected if Log entries show directory traversal attempts or unauthorized file access from authenticated sessions
A system is affected if Cybozu Garoon version 3.0.0 through 4.2.2 is installed and the application is accessible to authenticated users on the network.

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 the vendor-provided patch for Cybozu Garoon to address this vulnerability. Until patched, restrict network access to Garoon to trusted authenticated users only and monitor for unusual file access patterns.
