CVE-2006-2973


Description:
Three vulnerabilities have been reported in Calendar Express, which can be exploited by malicious people to conduct SQL injection or cross-site scripting attacks.

1) Input passed to the "cid" parameter in several scripts (e.g. "day.php", and "week.php", "month.php") isn't properly sanitised before being used in a SQL query. This can be exploited to manipulate SQL queries by injecting arbitrary SQL code.

2) Input passed to the "allwords" parameter in 'search.php" 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.

3) Input passed to the "catid" parameter in several scripts (e.g. "day.php", and "week.php", "month.php") isn't properly sanitised before being used in a SQL query. This can be exploited to manipulate SQL queries by injecting arbitrary SQL code.

The vulnerabilities have been reported in version 2.0. Other versions may also be affected.

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