How to exploit the SIPS 0.2.2 Vulnerability

[Kryptos2577]

Hi guys, I am new to this forum and after looking around nearly everywhere, I am unable to find an answer to this question and hoped you could help.

After scanning a website with nkito, the result showed that it was vulnerable to the sips vulnerability and that I could login as admin without knowing the password. However, after inputting the information in the url, I was simply redirected to the login page which also contains a captcha. Is there anyway I can still exploit the vulnerability such as using Metasploit?? Please help

And which website would that be?

Its on a ctf game I am trying to do rn. To do it, I have to hack the login but nikto shows very few vulnerabilities
