CVE-2021-43047Network attack vector

Script execution via stored and reflected XSS

Published Nov 16, 2021 · Updated Sep 16, 2024

Stored and reflected XSS in TIBCO PartnerExpress 6.2.1 and earlier allows remote authenticated users to execute scripts through a victim. TIBCO identifies the Interior Server and Gateway Server as affected but does not disclose the input fields or output contexts that fail to neutralize attacker-controlled content. A low-privileged account and interaction by a network-connected user are required; an administrator victim can expose full control of the affected system or local system.
