Official description

iTop is an web based IT Service Management tool. Versions prior to 3.2.1 are vulnerable to regular expression denial of service (ReDoS) that may, under some circumstances, affect iTop server. Version 3.2.1 doesn't use the affected variable in the regular expression. As a workaround, if iTop app_root_url is defined in the configuration file, then there is no possible way to exploit this ReDoS.
