How can this vulnerability be detected on my network or system? Can you suggest some commands?

[{'type': 'paragraph', 'content': 'This vulnerability can be detected by sending crafted HTTP GET requests to the vulnerable LigeroSmart endpoint and observing if the injected script is reflected in the response without proper sanitization.'}, {'type': 'paragraph', 'content': 'A typical detection method involves using curl or similar HTTP clients to send a request with a malicious payload in the Profile parameter and checking for the script execution or reflected payload in the response.'}, {'type': 'list_item', 'content': 'Example curl command to test the vulnerability: curl -i "http://localhost:9090/otrs/index.pl?Action=AgentTicketSearch;Subaction=Search;TakeLastSearch=1;SaveProfile=1;Profile=1%3C%2Fscript%3E%3Cscript%3Ealert(7777)%3C%2Fscript%3E"'}, {'type': 'list_item', 'content': 'Look for the injected script alert(7777) or the payload reflected in the HTTP response body indicating the presence of the reflected XSS vulnerability.'}] [2, 4]

What immediate steps should I take to mitigate this vulnerability?

Currently, no official patch or mitigation has been provided by the LigeroSmart project as they have not responded to the issue report.

Immediate mitigation steps include restricting access to the vulnerable endpoint to trusted users only, especially since exploitation requires authentication.

Avoid using the vulnerable versions of LigeroSmart (up to 6.1.26) if possible, or consider alternative products until a fix is available.

Implement web application firewall (WAF) rules to detect and block malicious payloads targeting the Profile parameter in requests to /otrs/index.pl.

Educate users to be cautious of suspicious links that may exploit this reflected XSS vulnerability.
