CVE-2024-46981: Redis' Lua library commands may lead to remote code execution

CriticalCVSS 9.8 · v3.1—Proof of concept Fix available

Noroxi assessment

Priority: Plan (action score 41/100)

Public proof-of-concept code exists (GitHub); there is no record of exploitation in the wild.
Probability of exploitation in the next 30 days: 8.1% (FIRST EPSS); higher than 94.9% of all records.
Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
Fixed version: redis redis 7.4.2; azl3 valkey 8.0.1-1 on Azure Linux 3.0 8.0.2-1; azl3 valkey 8.0.2-1 on Azure Linux 3.0 8.0.2-1.
Severity is disputed: the assigning authority (CNA) scores it 7.0, NVD 9.8.

Add it to your regular patch cycle. Upgrade to redis redis 7.4.2; azl3 valkey 8.0.1-1 on Azure Linux 3.0 8.0.2-1; azl3 valkey 8.0.2-1 on Azure Linux 3.0 8.0.2-1 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

Redis is an open source, in-memory database that persists on disk. An authenticated user may use a specially crafted Lua script to manipulate the garbage collector and potentially lead to remote code execution. The problem is fixed in 7.4.2, 7.2.7, and 6.2.17. An additional workaround to mitigate the problem without patching the redis-server executable is to prevent users from executing Lua scripts. This can be done using ACL to restrict EVAL and EVALSHA commands.
