Data disclosure and memory exhaustion via XXE
Published Sep 21, 2021 · Updated Sep 16, 2024
XML external entity injection in IBM Jazz for Service Management 1.1.3.10 allows remote authenticated users to read data or exhaust memory. IBM has not disclosed the affected parser or request handler; the published behavior is acceptance of crafted external entity references during XML processing. Low-privilege network access to the XML-processing function is required, and exploitation can disclose resources accessible to the service or degrade availability through memory consumption.
