Description:
Janek Vind "waraxe" has reported a vulnerability in Event Calendar, allowing malicious people to conduct cross-site scripting, script insertion and SQL injection attacks.

1) Path information can be disclosed in error pages by passing invalid input or accessing scripts directly.

Examples:
Calendar/config.php
Calendar/index.php
Calendar/submit.php

2) Input passed to various parameters isn't 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 a vulnerable site.

Examples:
modules.php?name=Calendar&file=submit&type=[code]
modules.php?name=Calendar&file=submit&op2=Preview&day=[code]
modules.php?name=Calendar&file=submit&op2=Preview&month=[code]
modules.php?name=Calendar&file=submit&op2=Preview&year=[code]
modules.php?name=Calendar&file=submit&op2=Preview&type=[code]

3) Comments aren't sanitised before being stored. This can be exploited to execute arbitrary script code in a user's browser session in context of an affected website when a an event with malicious comments is viewed.

4) Input passed to the "eid", "cid" and possibly other parameters isn't properly verified before it is used in a SQL query. This can be exploited to manipulate SQL queries.

Version 2.13 has been reported vulnerable. Other versions may also be vulnerable.

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

Use another product.
