CVE-2018-1774
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 · uneditedIBM API Connect 5.0.0.0, 5.0.8.4, 2018.1 and 2018.3.6 is vulnerable to CSV injection via the developer portal and analytics that could contain malicious commands that would be executed once opened by an administrator. IBM X-Force ID: 148692.
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 confidenceIBM API Connect versions 5.0.0.0, 5.0.8.4, 2018.1, and 2018.3.6 are vulnerable to CSV injection via the developer portal and analytics components. Attackers can embed malicious spreadsheet formula commands (e.g., =CMD) into data fields that get exported to CSV files; when an administrator opens the CSV in a spreadsheet application, the formulas execute locally on the administrator's machine.

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 IBM API Connect versionRun the command to display the API Connect version (typically via 'apic status' or checking the management node via 'apic manage:version' or reviewing the installation manifest)Affected if The version displayed is 5.0.0.0 through 5.0.8.4, or 2018.1.0 through 2018.3.6
-
Determine if developer portal is provisionedCheck the API Connect topology or configuration for enabled portal subsystems using 'apic topologies' or reviewing the management console for portal statusAffected if The developer portal component is enabled and accessible to end users who can submit data
-
Check if analytics component is enabledVerify analytics services are running via the management console or CLI commands such as 'apic analytics:status'Affected if Analytics collection and reporting is enabled for API usage data
-
Confirm CSV export capability existsAccess the analytics dashboard or developer portal admin interface and locate any export or download functions that generate CSV reportsAffected if CSV export functionality is present and available to users or administrators
-
Verify user-submitted data can reach exported reportsReview data flow from developer portal submissions or API invocation records through to any CSV export featureAffected if User-supplied input in API calls or portal forms can appear in exported CSV files
Your environment is affected if you run IBM API Connect versions 5.0.0.0-5.0.8.4 or 2018.1.0-2018.3.6 with the developer portal or analytics component enabled and CSV export functionality present.

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 IBM API Connect security patches or upgrades to a supported version. Until patched, restrict analytics export functionality to trusted users and warn administrators to disable automatic formula execution in spreadsheet applications when opening exported CSV files.
