Official description

IBM QRadar 7.6.0.0 through 7.6.0.1, and 7.5.0 through 7.5.0 UP 15 Interim Fix 005 has an XML External Entity (XXE) injection vulnerability. The vulnerability resides in the parseXmlPayload() function within the event processing pipeline ( q1labs_core.jar ). When at least one log source type is configured to use XML-format property autodetection, the system processes XML-formatted syslog events sent to port 514 (UDP/TCP) without authentication.

Source: the CVE record as published by its numbering authority, via NVD and CVE.org.

The underlying weakness: Improper Restriction of XML External Entity Reference

The product processes an XML document that can contain XML entities with URIs that resolve to documents outside of the intended sphere of control, causing the product to embed incorrect documents into its output.

How developers prevent this class of flaw

  • Many XML parsers and validators can be configured to disable external entity expansion.
