TITLE: ECW-Shop SQL Injection and Cross-Site Scripting Vulnerabilities


VERIFY ADVISORY: http://secunia.com/advisories/16459/

CRITICAL: Moderately critical

IMPACT: Cross Site Scripting, Manipulation of data

WHERE: >From remote

SOFTWARE: ECW-Shop 6.x http://secunia.com/product/5552/

DESCRIPTION: John Cobb has discovered some vulnerabilities in ECW-Shop, which can be exploited by malicious people to conduct cross-site scripting and SQL injection attacks.

1) Input passed to the "max" and "ctg" parameters isn't properly sanitised before being returned to users. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of a vulnerable site.

Examples: http://[host]/index.php?c=srch&ctg=[code] http://[host]/index.php?c=srch&max=[code]

2) Input passed to the "min" and "max" parameters isn't properly sanitised before being used in a SQL query. This can be exploited to manipulate SQL queries by injecting arbitrary SQL code.

It is also possible to add a negative quantity of items to the shopping cart, which causes the total price to become negative.

The vulnerabilities have been confirmed in version 6.02. Other versions may also be affected.

SOLUTION: Edit the source code to ensure that input is properly sanitised.
