CVE-2021-43048Network attack vector

Unauthenticated administrative takeover via undisclosed clickjacking mechanism

Published Nov 16, 2021 · Updated Sep 17, 2024

Clickjacking in TIBCO PartnerExpress 6.2.1 and earlier allows remote attackers to gain full administrative access over the network. TIBCO identifies the Interior Server and Gateway Server but has not disclosed which response lacks frame-embedding restrictions or how crafted framing produces the administrative action. Network access is sufficient, no victim interaction is required, and TIBCO describes full administrative access as theoretical.
