CVE-2020-5003Network attack vector

Information disclosure and memory exhaustion via XXE

Published Jun 11, 2021 · Updated Sep 16, 2024

XXE in IBM Financial Transaction Manager 3.2.4 allows remote attackers to disclose sensitive information or exhaust memory via XML data. IBM identifies XML processing as the affected locus but does not disclose the parser, input path, or unsafe external-entity resolution operation. No authentication or user interaction is required, while high attack complexity limits reachability and the reported consequences are data disclosure and memory consumption.
