CVE-2023-26024

Adjacent-network information disclosure via risky cryptography

Published Dec 1, 2023 · Updated Sep 16, 2024

Information disclosure in IBM Planning Analytics on Cloud Pak for Data 4.0 allows remote attackers to read sensitive data over a shared network. IBM identifies insecure network communication and a risky cryptographic algorithm, but does not disclose the affected protocol, cryptographic primitive, or data exposed. Exploitation requires adjacent network access, needs no authentication or user interaction, and affects confidentiality without reported modification or interruption.
