Unable to connect to target using a SOCKS5 proxy on Kali (WSL 2)

[aarivex]

Describe the bug
The sqlmap build thats shipped with Kali, version 1.4.12#stable in the time I'm writing this, has connectivity issues when using a proxy, SOCKS5 in my case, to connect to the target. Weirdly, this cannot be reproduced when cloned directly from this repo.

To Reproduce
sqlmap --random-agent --proxy socks5://frankfurt.perfect-privacy.com:21 --proxy-cred "<user>:<pass>" -u <host>

Expected behavior
A successful connection to the specified host through the specified proxy.

Screenshots

Running environment:

• sqlmap 1.4.12, stable
• Kali Linux on WSL 2 (Windows Subsystem for Linux), on top on Windows 10

I've found one open SOCKS5 for testing. It required large --timeout and --random-agent to work in the first place:

Another (better example):

p.s. if you "feel" that you are having problems with provided credentials, here I can't help you as I don't have such examples to reproduce

@aarivex this could be the same Issue as #4479. Please update to the latest revision and retry
