TITLE: ExtCalendar calendar.php Cross-Site Scripting Vulnerabilities

SECUNIA ADVISORY ID: SA19321

VERIFY ADVISORY: http://secunia.com/advisories/19321/

CRITICAL: Less critical

IMPACT: Cross Site Scripting

WHERE: >From remote

SOFTWARE: ExtCalendar 1.x http://secunia.com/product/8810/

DESCRIPTION: Soot has discovered some vulnerabilities in ExtCalendar, which can be exploited by malicious people to conduct cross-site scripting attacks.

Input passed to the "month", "year", "prev", and "next" parameters in calendar.php is not properly sanitised 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.

The vulnerabilities have been confirmed in version 1.1. Other versions may also be affected.

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