CVE-2021-43046Network attack vector

Unauthenticated session token disclosure via URL

Published Nov 16, 2021 · Updated Sep 16, 2024

Session token disclosure in TIBCO PartnerExpress 6.2.1 and earlier allows remote attackers to obtain tokens via network requests. The Interior Server and Gateway Server components expose session tokens through URL handling, allowing tokens to be captured. Human interaction by another person is required, and a captured token can provide full administrative access when the victim holds administrator privileges.
