CVE-2023-45145 Information

Description

Redis is an in-memory database that persists on disk. On startup Redis begins listening on a Unix socket before adjusting its permissions to the user-provided configuration. If a permissive umask(2) is used this creates a race condition that enables during a short period of time another process to establish an otherwise unauthorized connection. This problem has existed since Redis 2.6.0-RC1. This issue has been addressed in Redis versions 7.2.2 7.0.14 and 6.2.14. Users are advised to upgrade. For users unable to upgrade it is possible to work around the problem by disabling Unix sockets starting Redis with a restrictive umask or storing the Unix socket file in a protected directory.
