Privilege escalation via stored XSS
Published Sep 14, 2022 · Updated Aug 4, 2024
Incorrect access control in Yellowfin Business Intelligence 7.3 allows remote authenticated users to escalate privilege through the MIAdminStyles.i4 Admin UI. The component stores attacker-controlled script content without adequate authorization enforcement, allowing a victim administrator to execute the payload in the application context. Exploitation requires a low-privilege account and user interaction, and can grant administrative control with confidentiality, integrity, and availability impact.
