PHP Event Calendar through 2021-11-04 allows persistent cross-site scripting (XSS), as demonstrated by the /server/ajax/events_manager.php title parameter. This can be exploited by an adversary in multiple ways, e.g., to perform actions on the page in the context of other users, or to deface the site.

A Cross-Site Scripting (XSS) issue was discovered in php-calendar before 2017-03-03. The vulnerability exists due to insufficient filtration of user-supplied data (errorMsg) passed to the "php-calendar-master/error.php" URL. An attacker could execute arbitrary HTML and script code in a browser in the context of the vulnerable website.

Multiple cross-site scripting (XSS) vulnerabilities in index.php in PHP-Calendar before 2.0 Beta7 allow remote attackers to inject arbitrary web script or HTML via the (1) description and (2) lastaction parameters.

Multiple absolute path traversal vulnerabilities in PHP-Calendar 1.1 allow remote attackers to include and execute arbitrary local files via a full pathname in the configfile parameter to (1) update08.php or (2) update10.php. NOTE: in some environments, this can be leveraged for remote file inclusion by using a UNC share pathname or an ftp, ftps, or ssh2.sftp URL.

SQL injection vulnerability in search.php for PHP-Calendar before 0.10.3 allows remote attackers to execute arbitrary SQL commands via unknown vectors.

Multiple PHP remote file inclusion vulnerabilities in Sean Proctor PHP-Calendar before 0.10.1, as used in Commonwealth of Massachusetts Virtual Law Office (VLO) and other products, allow remote attackers to execute arbitrary PHP code via a URL in the phpc_root_path parameter to (1) includes/calendar.php or (2) includes/setup.php.
