Patch Published: 2011-04-19
CVE [?]: N/A
CPE [?]: N/A

Synopsis

The remote web server hosts a web application that allows arbitrary command execution.

Description

The remote web server hosts Spree, an open source e-commerce application for Ruby on Rails.

The version of this application installed on the remote host has a flaw in the third-party 'rd_searchlogic' Ruby gem. An unauthenticated, remote attacker can inject arbitrary Ruby code via the 'search[instance_eval]' parameter of the 'api/orders.json' script to be executed on the remote host subject to the privileges under which the web server operates.

Solution

Upgrade to Spree version 0.50.x or later.

Public Exploits

Target Network Port(s): 80
Target Asset(s): Services/www
Exploit Available: True (Metasploit Framework, Exploit-DB)
Exploit Ease: Exploits are available
