CVE-2024-31228 | Denial-of-service due to unbounded pattern matching in Redis

Redis is an open source, in-memory database that persists on disk. Authenticated users can trigger a denial-of-service by using specially crafted, long string match patterns on supported commands such as `KEYS`, `SCAN`, `PSUBSCRIBE`, `FUNCTION LIST`, `COMMAND LIST` and ACL definitions. Matching of extremely long patterns may result in unbounded recursion, leading to stack overflow and process crash. This problem has been fixed in Redis versions 6.2.16, 7.2.6, and 7.4.1. Users are advised to upgrade. There are no known workarounds for this vulnerability.

5.5 3.1 MEDIUM
CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H Click to expand
Attack vector (AV:L)
They already need access on the box, or another person has to do something wrong; it’s not a remote drive-by.
Attack complexity (AC:L)
Once they can reach the bug, pulling it off is straightforward—no weird race conditions or rare setup.
Privileges required (PR:L)
A normal user session is enough; they don’t have to be admin.
User interaction (UI:N)
Nobody has to click “OK” or open a trap file; it can work without a victim helping.
Scope (S:U)
Damage stays in the same “trust bubble” as the broken component—no big spill into unrelated systems.
Confidentiality (C:N)
Doesn’t really leak secrets in a meaningful way.
Integrity (I:N)
Data isn’t meaningfully altered or forged.
Availability (A:H)
Could take the service down hard or make it unusable for people who depend on it.
