Hat-Squad Advisory: SQL injection and XSS Vulnerabilities in HELM
November 2, 2004 

Product: HELM Web Hosting Control Panel
Vendor URL: http://helm.webhostautomation.com
Version: HELM 3.1.19 and lower
Vulnerability: SQL injection and XSS 
Release Date: November 2, 2004

Vendor Status: 
Informed on 28 October 2004
Response: 1 November 2004
Fixed on 1 November 2004

Description:

Helm is a multi-server management and control system for Windows 2000 and 2003 based web hosts. The system is designed 
for any size web hosting companies, datacenters and ISPs, which require a solid platform that automates all of the 
day-to-day tasks that would otherwise require highly skilled man power, and large work forces.

Details:

HELM Messaging module is used by resellers to keep customers up to date with the latest information. System information 
messages can also be sent to the messaging service to inform resellers and users of any problems. Due to the lack of 
proper input validation in this module, it's possible both to inject SQL commands and malicious script to the system to 
gain "ADMIN" level access to the system.

SQL Injection:

There is no input validation on "messageToUserAccNum" parameter of "compose message" form. Therefore it's possible to 
execute SQL query by passing arbitrary SQL code.

By using a Man in The Middle HTTP tool, it's possible to inject sql query in "messageToUserAccNum" value, in the form 
of: 

        [username]',[messageid],[isread]);  [arbitrary sql query];--

Example:

A User with reseller level access can send the following value that will add an account "root" with ADMIN privilege and 
blank password to the account table in HELM database:

xxxx',10,0);  insert into account(accountnumber,accounttype,accountpassword) values('root',0,'');--


Cross Site Scripting:

XSS attack code could be sent in "Subject" field of "compose message" form. Viewing the message by victim user (usually 
ADMIN) will run the attack code.

Solution:

Update Your HELM software version to 3.1.20 .
