# Redis Debian-specific Redis Servers: Debian-specific Redis Server Lua Sandbox Escape Vulnerability

Debian's packaged Redis server has a Lua sandbox escape that lets a script break out of the sandbox. An attacker who can run Lua on the server can execute code as the Redis process.

_Summary, check and fix written by a model from the sources; labelled as such._

## Affected

- vendor:Redis Debian-specific Redis Servers affected ? fixed ?

## Fix

Apply the Debian security update for the redis packages per vendor instructions (CISA required action); the exact package version is unknown from the sources.

## From the sources

It was discovered, that redis, a persistent key-value database, due to a packaging issue, is prone to a (Debian-specific) Lua sandbox escape, which could result in remote code execution.
