Detection Guidance

Detection of this vulnerability involves verifying if your Kentico Xperience installation is version 13.0.120 or earlier and checking for the presence of reflected XSS in the administration interface. Since it requires authenticated access and user interaction, manual testing by logging into the admin interface and attempting to inject scripts in input fields can help identify the issue. Automated scanning tools for reflected XSS may also be used but must be run with authenticated sessions. Specific commands are not provided in the available resources. [1]
