CVE-2020-4881Network attack vector

Sensitive information disclosure via unchecked TLS hostnames

Published Jan 19, 2021 · Updated Sep 17, 2024

Origin validation failure in IBM Planning Analytics Workspace 2.0 allows remote attackers to read sensitive information via crafted requests. Workspace accepts TLS server certificates without matching the certificate hostname to the intended server, allowing an attacker-controlled endpoint to be trusted. Exploitation requires a network path capable of steering the outbound TLS connection, and the reported consequence is confidentiality loss without data modification or service interruption.
