CVE-2023-31001Public exploit

Private-key disclosure via world-readable temporary file

Published Jan 11, 2024 · Updated Nov 3, 2025

Information disclosure in IBM Security Verify Access 10.0.0.0 through 10.0.6.1 allows local users to read private keys from temporary files. The build_health_check_config function in /usr/sbin/bootstrap.sh exports DSC server and client keys to predictable /tmp/health_check.p12 under the default 022 umask. Local access to the container during instance startup is required, and disclosure is limited to the exported private keys.
