I discovered a known vulnerability, where the PoC code was like this:

'{https://example.com" | ls -la"}'

But that had to be modified, where | was replaced with the ; character. My question is, how do I know which character needs to be replaced? As general asking. Is it depending on the terminator characters.. or just "guessing"? And if so, how do you approach this? I'm reading through the documentation files, but don't get it to be honest
