→Send a GET request to /core/authorize.php and inspect the response body for the strings 'getHashSalt' AND 'RuntimeException' simultaneously — their co-presence indicates the full path disclosure is triggered. ↗
→Scan HTTP response bodies from /core/authorize.php for a regex pattern matching a filesystem path ending in 'settings.php' (e.g. r'(/.*?settings\.php)') to extract the disclosed server path. ↗
→The vulnerability is exploitable with a plain unauthenticated GET request to /core/authorize.php — no authentication or special parameters are required. ↗
→Shodan queries 'http.component:"drupal"' and 'cpe:"cpe:2.3:a:drupal:drupal"' can be used to identify potentially vulnerable internet-facing Drupal instances for proactive scanning. ↗

·The vulnerability triggers Full Path Disclosure even when Drupal's error logging is set to 'None', meaning standard error-suppression configuration does NOT mitigate exposure. ↗
·The root cause is hash_salt being configured as file_get_contents() referencing a non-existent file; the RuntimeException/getHashSalt error leaks the full server filesystem path in the HTTP response. ↗
