CVE-2019-4062
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 i2 Intelligent Analyis Platform 9.0.0 through 9.1.1 is vulnerable to an XML External Entity Injection (XXE) attack when processing XML data. A remote attacker could exploit this vulnerability to expose sensitive information or consume memory resources. IBM X-Force ID: 157007.
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 i2 Intelligent Analysis Platform versions 9.0.0 through 9.1.1 is vulnerable to XML External Entity Injection (XXE). The application fails to properly disable external entity processing when parsing XML data, allowing a remote attacker to exploit this by crafting malicious XML that references external entities to read sensitive files from the server or cause memory exhaustion through recursive entity expansion.

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.
-
Verify IBM i2 Intelligent Analysis Platform is installedCheck for the product in common installation directories such as C:\Program Files\IBM\i2\ or /opt/IBM/i2/ on Linux. On Windows, also check the list of installed programs or running services for 'IBM i2' entries.Affected if The product is found on the system
-
Determine the installed version numberLocate version information in the installation directory, typically in an About dialog within the application, a version.txt file, or product-specific metadata files in the installation folder.Affected if The version is 9.0.0, 9.1.0, or 9.1.1 (falls within 9.0.0 through 9.1.1 inclusive)
-
Identify XML input vectorsExamine the application's interfaces for any features that accept XML data: file import functionality, data ingestion endpoints, API interfaces, or any configuration import features.Affected if The application processes or imports XML files or data from external sources
-
Check XML parser security configurationIf accessible, examine the application's configuration files or XML processor settings for properties controlling external entity resolution. Look for settings related to 'external entities', 'DTD processing', or 'entity expansion' in parser configuration files.Affected if External entity processing is not explicitly disabled or set to secure (the application is vulnerable by default in affected versions)
The environment is affected if IBM i2 Intelligent Analysis Platform version 9.0.0 through 9.1.1 is installed and the application processes XML input, since the XXE vulnerability exists in how the application handles XML parsing in those versions.

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 dataDisable XML external entity (XXE) processing in the application's XML parser configuration and implement strict input validation for all XML data. Upgrade to a patched version if available from IBM.
