CVE-2019-4751Network attack vector

Unauthenticated information disclosure via API stack traces

Published Apr 24, 2020 · Updated Sep 16, 2024

Information disclosure in IBM Cloud App Management 2019.3.0 and 2019.4.0 allows remote attackers to read stack traces via API requests. Certain API request handlers return internal stack traces instead of suppressing implementation details when processing an error. No authentication or user interaction is required; the disclosed details aid further attacks, while integrity and availability are unaffected.
