1) Security Features

EUVDB-ID: #VU31401

Risk: Medium

CVSSv3.1: 6.4 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:N/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2016-10517

CWE-ID: CWE-254 - Security Features

Exploit availability: No

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).

Mitigation

Install update from vendor's website.

Vulnerable software versions

Redis: 3.2.0 - 3.2.6
