Ravens PHP Scripts - Link CMS Cross-Site Scripting and SQL Injection

SECUNIA ADVISORY ID: SA23107

VERIFY ADVISORY: http://secunia.com/advisories/23107/

CRITICAL: Moderately critical

IMPACT: Cross Site Scripting, Manipulation of data

SOFTWARE: LINK Content Management Server - http://secunia.com/product/12832/

DESCRIPTION: Ivan Markovic has reported some vulnerabilities in Link CMS, which can be exploited by malicious people to conduct SQL injection and cross-site scripting attacks.

1) Input passed to the "IDMeniGlavni" and "IDStranicaPodaci" parameters is not properly sanitised before being used in SQL queries. This can be exploited to manipulate SQL queries by injecting arbitrary SQL code.

Examples:
http://[host]/navigacija.php?IDMeniGlavni=[code]&IDStranicaPodaci=228&jezik=lat
http://[host]/prikazInformacije.php?IDStranicaPodaci=[code]

2) Input to the "txtPretraga" parameter in naprednaPretraga.php is not properly sanitized before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.

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