Description

The vulnerability allows a remote non-authenticated attacker to gain access to sensitive information.

networking.c in Redis before 3.2.7 allows "Cross Protocol Scripting" because it lacks a check for POST and Host: strings, which are not valid in the Redis protocol (but commonly occur when an attack triggers an HTTP request to the Redis TCP port).
