Steps To Reproduce:

1.I was going to the site: █████ and on the home page I clicked on personal and the site redirected me to another site which is: ██████████ and on this site on which I was redirected I saw "link your NIN" and I went to this site and after listing I found an impressive thing which is the Tiny filemanager and to authenticate myself I bypass it with default credentials to access it. The default credentials are: Login Details: ████/████ | user/12345 and I had access to the panel and I had privileges like modify, upload, delete

Impact

The impact of authentication vulnerabilities can be very severe. Once an attacker has either bypassed authentication or has brute-forced their way into another user's account, they have access to all the data and functionality that the compromised account has.
