Descriptions
Redis is an in-memory database that persists on disk. Prior to versions 6.2.7 and 7.0.0, an attacker attempting to load a specially crafted Lua script can cause NULL pointer dereference which will result with a crash of the redis-server process. The problem is fixed in Redis versions 7.0.0 and 6.2.7. An additional workaround to mitigate this problem without patching the redis-server executable, if Lua scripting is not being used, is to block access to `SCRIPT LOAD` and `EVAL` commands using ACL rules.
Redis es una base de datos en memoria que persiste en el disco. Antes de las versiones 6.2.7 y 7.0.0, un atacante que intente cargar un script Lua especialmente diseñado puede causar una derivación de puntero NULL que resultará en una caída del proceso del servidor Redis. El problema se ha solucionado en las versiones de Redis 7.0.0 y 6.2.7. Una solución adicional para mitigar este problema sin necesidad de parchear el ejecutable de redis-server, si no se utilizan scripts de Lua, es bloquear el acceso a los comandos `SCRIPT LOAD` y `EVAL` mediante reglas ACL
