Technical details
A stored XSS vulnerability exists in the CustomerAdministration portal where user properties (such as the "secondName" parameter) are not properly sanitized before storage and execution. An authenticated attacker with administrative access can inject JavaScript code that persists in the database and executes when other privileged users view the edited user entry or user group overview. The vulnerability requires prior authentication and administrative privileges but affects any privileged user who subsequently accesses the malicious record.
