The login portal for the Automated Logic WebCTRL/WebCTRL OEM web application contains a vulnerability that allows for reflected XSS attacks due to the operatorlocale GET parameter not being sanitized. This issue impacts versions 6.5 and below. This issue works by passing in a basic XSS payload to a vulnerable GET parameter that is reflected in the output without sanitization.
