TITLE:
Cosmoshop SQL Injection and Disclosure of Sensitive Information

SECUNIA ADVISORY ID:
SA20177

VERIFY ADVISORY:
http://secunia.com/advisories/20177/

CRITICAL:
Moderately critical

IMPACT:
Manipulation of data, Exposure of sensitive information

WHERE:
>From remote

SOFTWARE:
Cosmoshop 8.x
http://secunia.com/product/5635/

DESCRIPTION:
l0om has reported some vulnerabilities in Cosmoshop, which can be
exploited by malicious users to disclose sensitive information and by
malicious people to conduct SQL injection attacks.

1) Input passed to the "file" parameter in edit_mailtexte.cgi and
bestmail.cgi isn't properly sanitised before being used to view
files. This can be exploited to disclose the content of arbitrary
files via directory traversal attacks.

Examples:
http://[host]/cgi-bin/admin/bestellvorgang/edit_mailtexte.cgi?file=../../[file]%00
http://[host]/cgi-bin/admin/bestmail.cgi?action=view&file=../../[file]%00

Successful exploitation requires administrative privileges.

2) Input passed to the "artnum" parameter in lshop.cgi isn't properly
sanitised before being used in a SQL query. This can be exploited to
manipulate SQL queries by injecting arbitrary SQL code.

Example:
http://[host]/cgi-bin/lshop.cgi?action=showdetail&artnum=[code]&wkid=2002g&ls=d&nocache=

The vulnerabilities have been reported in version 8.11.106. Other
versions may also be affected.

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