CVE-2021-39054Network attack vector

Authenticated click hijacking via undisclosed framing flaw

Published Dec 13, 2021 · Updated Sep 17, 2024

Clickjacking in IBM Storage Defender Copy Data Management 2.2.13 and earlier allows remote attackers to hijack authenticated users' clicks. IBM identifies the web interface as affected but has not published which response or framing control permits a malicious site to overlay it. Exploitation requires low privileges and persuading an authenticated user to visit a malicious site; successful clicks trigger unintended interface actions.
