CVE-2020-4406Network attack vector

Authenticated action hijacking via frameable web interface

Published Jun 15, 2020 · Updated Sep 17, 2024

Clickjacking in IBM Spectrum Protect Client and Space Management affected releases allows remote authenticated users to hijack clicks. The web interfaces permit pages to render in attacker-controlled frames, where deceptive overlays redirect a signed-in victim's intended clicks. Exploitation requires a malicious website and victim interaction; resulting actions are limited to functions available in the victim's session.
