Debian-specific Redis Server Lua Sandbox Escape Vulnerability

Redis · Debian-specific Redis Servers

Summary

A flaw in the Debian-specific builds of the Redis server, caused by a packaging issue, allows a Lua sandbox escape in the Lua scripting component of the persistent key-value database. An attacker with network access can exploit it without authentication or user interaction to achieve remote code execution.

Official description · NVD

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.
