CVE-2019-4707Network attack vector

Information disclosure and service interruption via XXE

Published Jan 28, 2020 · Updated Sep 16, 2024

XML external entity injection in IBM Security Verify Access Appliance 9.0.7.0 allows remote authenticated users to read sensitive data. The XML-processing path resolves attacker-controlled external entity references without sufficient restriction, but IBM has not disclosed the affected endpoint or parser. Access to an authenticated network interface is required; exploitation can disclose appliance-accessible information or consume memory until service is interrupted.
