CVE-2021-21444Network attack vector

Clickjacking via duplicate frame-protection headers

Published Feb 9, 2021 · Updated Aug 3, 2024

Clickjacking in SAP BusinessObjects Business Intelligence Platform 410, 420, and 430 allows remote attackers to trigger unintended user actions. The CMC and BI Launchpad login pages emit duplicate X-Frame-Options headers, and inconsistent user-agent handling can nullify the framing restriction. Exploitation requires interaction with attacker-controlled framed content; resulting actions are limited to those available in the victim's session.
