Stored Cross-site scripting (XSS) vulnerability allows authenticated and unauthenticated remote attackers to inject arbitrary web script or HTML into HTTP/GET parameter which reflects/store the user input without sanitization.
Step-by-step instructions and PoC
The Web application does not properly check the parameters sent as input from clients before they are re-included within the HTTP pages returned by the application. In particular, the web gui is affected by the stored type of this vulnerability. Due to the lack of validation of user input, it allows an attacker to inject arbitrary javascript code which is then reflected in the Activity Log page of the application. The attack can be performed both pre and post authentication.
Below are the evidences with the vulnerability details and the payloads used.
The below payload is an example. The vulnerability can be exploited using every functionality which generates a log entry in the ActivityLog page of the web application
