XML External Entity Injection in Batch Processing System

Publication date: 2026-09-11

Last updated on: 2026-09-11

Assigner: ICS-CERT

Description
When XML batch processing is turned on and the XPath option is selected, the raw batch input goes through a default XPath/JAXP setup with no entity restrictions, so XXE injection can allow data exfiltration and denial-of-service attacks.

Executive Summary

This vulnerability involves XML batch processing with XPath enabled. When enabled, raw batch input uses a default XPath/JAXP setup without entity restrictions, allowing XML External Entity (XXE) injection. This can lead to data exfiltration and denial-of-service attacks.

Impact Analysis

An attacker could exploit this to steal sensitive data or disrupt services. Data exfiltration may expose confidential information, while denial-of-service could render systems unavailable. The impact depends on system configuration and data sensitivity.

Compliance Impact

This vulnerability could lead to unauthorized data access, violating GDPR's data protection requirements and HIPAA's safeguards for protected health information. Non-compliance may result in legal penalties and reputational damage.

Mitigation Strategies

Disable XML batch processing if not required. If enabled, ensure entity restrictions are enforced in XPath/JAXP setups to prevent XXE injection. Validate and sanitize all XML inputs.
