Sensitive-data exposure and memory exhaustion via crafted XML
Published Apr 7, 2020 · Updated Aug 4, 2024
XXE in HCL AppScan Standard 9.0.3.14 and earlier allows remote attackers to expose sensitive data or consume memory through crafted XML. HCL has not identified the XML-processing component or disclosed how its parser handles external entity declarations. Exploitation requires AppScan to process attacker-controlled XML; the reported consequences are sensitive-data exposure and memory exhaustion, with no integrity impact.
