Name of the Vulnerable Software and Affected Versions php-calendar versions prior to 2017-03-03

Description A Cross-Site Scripting (XSS) issue exists due to insufficient filtration of user-supplied data, specifically the errorMsg variable, passed to the "php-calendar-master/error.php" URL. This allows an attacker to execute arbitrary HTML and script code in a browser in the context of the vulnerable website.

Recommendations For versions prior to 2017-03-03, update to a version released after 2017-03-03 to resolve the issue. As a temporary workaround, consider filtering or validating user-supplied data, especially the errorMsg variable, to prevent malicious input from being executed. Restrict access to the "php-calendar-master/error.php" URL until the issue is resolved.
