CWE ID 668

Summary

CVE-2023-45145 is a vulnerability affecting Redis, an in-memory database that listens on a Unix socket during startup. If a permissive umask is used, this creates a race condition, allowing unauthorized connections before Redis adjusts its permissions. This issue, present since Redis 2.6.0-RC1, has been addressed in versions 7.2.2, 7.0.14, and 6.2.14. Users are advised to upgrade as soon as possible to mitigate the risk. Alternatively, disabling Unix sockets, using a restrictive umask, or storing the Unix socket file in a protected directory are workarounds for those unable to upgrade.
