iTop is a web-based IT Service Management tool that has been identified to be vulnerable to a Regular Expression Denial of Service (ReDoS) attack in versions prior to 3.2.1. This vulnerability could potentially disrupt the iTop server under specific circumstances. However, users can apply a workaround by defining the app_root_url in their configuration file, effectively preventing possible exploitation of this ReDoS.
