CVE-2020-4815Network attack vector

Unauthenticated information disclosure via HTTP response headers

Published Jan 27, 2021 · Updated Sep 16, 2024

Information disclosure in IBM Cloud Pak for Security 1.4.0.0 allows remote attackers to read sensitive data from HTTP response headers. IBM identifies the exposed locus only as HTTP response headers and does not disclose which header is populated or what server operation leaks the data. The interface is network-reachable without authentication, and the disclosed header data supports further attacks but does not directly alter data or interrupt service.
