-u URL, --url URL URL of the target Jira instance e.g. '-u
https://localhost:8080'
-c, --check Only check the Jira version; doesn't send SSRF attempt
Host probablemente vulnerable:
$ python3 jira.py -u https://localhost:8080
[-] Testing https://localhost:8080...
[-] Checking for version...
[-] Jira version appears to be: 8.3.4
[-] Sending SSRF test...
[+] Host appears to be vulnerable!
Host probablemente no vulnerable:
$ python3 jira.py -u https://localhost:8080
[-] Testing https://localhost:8080...
[-] Checking for version...
[-] Jira version appears to be: 8.4.1
[-] Sending SSRF test...
