Kwetsbaarheden verholpen in Redis

Published Oct 8, 2025 · Updated Oct 8, 2025 · nl

Vendor: Redis Product: Redis

Summary

Redis heeft kwetsbaarheden verholpen in versies 8.2.1 en lager.

Details

Interpretaties
De kwetsbaarheden bevinden zich in de Lua-scriptingengine van Redis, die kunnen worden misbruikt door geauthenticeerde gebruikers. Dit kan leiden tot remote code execution, out-of-bounds data access of servercrashes. De kwetsbaarheden kunnen de integriteit en beveiliging van systemen die deze versies gebruiken in gevaar brengen. De kwetsbaarheden zijn opgelost in versie 8.2.2.
Veel Redis‑implementaties hebben geen pre‑authenticatie of ACL‑gebaseerde autorisatie ingeschakeld; dit vergroot het risico op exploitatie.

Onderzoekers hebben Proof of Concept (PoC) code vrijgegeven die kwetsbaarheid CVE-2025-49844 aantoont en waarmee de kwetsbaarheid kan worden misbruikt.

Oplossingen
Redis heeft updates uitgebracht om de kwetsbaarheden te verhelpen. Zie bijgevoegde referenties voor meer informatie.
