CVE-2019-5991
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 · uneditedSQL injection vulnerability in the Cybozu Garoon 4.0.0 to 4.10.3 allows remote authenticated attackers to execute arbitrary SQL commands 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 confidenceSQL injection vulnerability in Cybozu Garoon versions 4.0.0 to 4.10.3 allows remote authenticated attackers to execute arbitrary SQL commands via unspecified vectors in the application.

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 Garoon versionAccess the Garoon system administration screen or check the version information via the vendor-provided method (typically found in the system settings or via the /g/version endpoint depending on deployment)Affected if Version is 4.0.0 through 4.10.3 inclusive
-
Verify remote access is enabledCheck whether Garoon is configured to allow remote/network access from untrusted networksAffected if The application is reachable from remote/outside networks without proper network segmentation
-
Confirm authentication mechanismsReview user authentication settings to determine if external or low-privilege users can authenticate to the Garoon applicationAffected if External users or low-privilege accounts can authenticate to the system
-
Check for SQL injection exposureSince the vulnerability exists in unspecified application vectors, review any custom configurations, third-party integrations, or user input handling that may interact with database queriesAffected if The application processes user-supplied input through database queries without proper sanitization
If the installed Garoon version falls between 4.0.0 and 4.10.3 and the application accepts remote authenticated users, the environment is potentially affected by this SQL injection vulnerability.

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 patch (upgrade to Garoon 4.10.4 or later) and conduct code review to identify and remediate any instances of unsanitized SQL query construction in the application.
