Ravens PHP Scripts - Zen Cart SQL Injection and File Inclusion Vulnerabilities

TITLE: Zen Cart SQL Injection and File Inclusion Vulnerabilities

SECUNIA ADVISORY ID: SA21484

VERIFY ADVISORY: http://secunia.com/advisories/21484/

CRITICAL: Highly critical

IMPACT: Manipulation of data, System access

WHERE: >From remote

SOFTWARE: Zen Cart 1.x -- http://secunia.com/product/3488/

DESCRIPTION: James Bercegay has reported some vulnerabilities in Zen Cart, which can be exploited by malicious people to conduct SQL injection attacks and compromise a vulnerable system.

1) Input passed to the "ipn_get_stored_session", "whos_online_session_recreate", and the "add_cart" functions is not properly sanitised before being used in an SQL query. This can be exploited to manipulate SQL queries by injecting arbitrary SQL code.

2) Certain input is not properly verified before being used to include files. This can be exploited to include arbitrary files from local or external resources.

Examples:
http://[host]/index.php?autoLoadConfig[999][0][autoType]=include&autoLoadConfig[999][0][loadFile]=[remote file] * The "typefilter" parameter (only local resources)

The vulnerabilities have been reported in version 1.3.0.2. Other versions may also be affected.

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