CVE-2021-29785Network attack vector

Information disclosure via missing HSTS enforcement

Published Jan 20, 2022 · Updated Sep 17, 2024

Information disclosure in IBM Security QRadar SOAR 42 and 43 allows remote attackers to read sensitive data through man-in-the-middle interception. The web interface fails to enable the HTTP Strict-Transport-Security response header, so browsers can initiate or follow an HTTP connection that an on-path attacker can intercept. Exploitation requires a man-in-the-middle position; the published impact is limited to confidentiality, with no integrity or service interruption reported.
