Sensitive-data disclosure via unauthenticated inter-host key exchange
Published Dec 1, 2021 · Updated Sep 16, 2024
Key exchange weakness in inter-host communications in IBM QRadar SIEM 7.3 and 7.4 allows remote attackers to read sensitive data. The server establishes inter-host encryption keys without authenticating the peer, allowing an attacker on the communications path to impersonate a host and intercept protected traffic. Exploitation requires a man-in-the-middle position between QRadar hosts; the published impact is limited to disclosure, with no integrity or availability impact.
