An out-of-date version of Redis shipped with NI SystemLink Server is susceptible to multiple vulnerabilities, including CVE-2022-24834. This affects NI SystemLink Server 2024 Q1 and prior versions. It also affects NI FlexLogger 2023 Q2 and prior versions which installed this shared service.

Redis is an in-memory database that persists on disk. A specially crafted Lua script executing in Redis can trigger a heap overflow in the cjson library, and result with heap corruption and potentially remote code execution. The problem exists in all versions of Redis with Lua scripting support, starting from 2.6, and affects only authenticated and authorized users. The problem is fixed in versions 7.0.12, 6.2.13, and 6.0.20.
