CVE-2016-6805
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 · uneditedApache Ignite before 1.9 allows man-in-the-middle attackers to read arbitrary files via XXE in modified update-notifier documents.
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 confidenceApache Ignite before 1.9 contains an XXE (XML External Entity) vulnerability in its update-notifier functionality. An attacker performing a man-in-the-middle attack can craft malicious XML with external entity references in update notification documents to read arbitrary files from the server's filesystem.

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 Apache Ignite installation and versionLocate Apache Ignite installation and retrieve version information (e.g., check ignition sh scripts, JAR file names, or run version commands if available). Compare the installed version against the affected range: versions 1.8 and below are affected.Affected if Installed Apache Ignite version is 1.8 or lower (any version up to and including 1.8).
-
Determine if update-notifier functionality is enabledInspect Apache Ignite configuration files (typically ignite.xml, ignite-default.xml, or custom configuration XMLs) for update-notifier related settings. Look for classes or modules related to update notifications, version checking, or automatic update features.Affected if The update-notifier module or update checking feature is enabled in the Ignite configuration.
-
Verify XML processing in update notificationsReview logs, configuration, or code related to update notification processing. Check if the system makes HTTP/HTTPS requests to fetch update notification documents that are then parsed as XML.Affected if Update notifications are fetched and parsed as XML, indicating the vulnerable XML parser is in use.
A user is affected if Apache Ignite version 1.8 or lower is installed AND the update-notifier functionality is enabled, allowing XML external entity processing on potentially untrusted update documents.

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 dataUpgrade Apache Ignite to version 1.9 or later to incorporate the XXE vulnerability fix.
