CVE-2024-31896Network attack vector

Sensitive-information decryption via SHA-1 cipher suites

Published Mar 25, 2025 · Updated Sep 1, 2025

Weak cryptography in IBM SPSS Statistics 26.0, 27.0.1, 28.0.1, and 29.0.2 allows remote attackers to decrypt sensitive information. Statistics Server retains SHA-1 cipher suites for SSL connections, allowing protected communications to rely on a deprecated cryptographic primitive. The published assessment requires no credentials or user interaction but has high attack complexity; IBM has not disclosed the exact decryption workflow.
