cookie PHPMYBCAdmin=LOGGEDIN↗

path admin.php↗

command javascript:document.cookie = "PHPMYBCAdmin=LOGGEDIN; path=/";↗

• → Detect unauthenticated requests to admin.php that carry the cookie PHPMYBCAdmin=LOGGEDIN without a preceding successful POST login — this indicates authentication bypass exploitation. ↗
• → Alert on HTTP requests to admin.php where the Cookie header contains 'PHPMYBCAdmin=LOGGEDIN' but no corresponding POST body with login credentials is present in the session. ↗

• · The vulnerable cookie value is a static, hardcoded string ('LOGGEDIN'); any request presenting this exact cookie value to admin.php is granted full administrative access regardless of credentials. ↗
• · The vulnerability affects only phpMyBlockchecker version 1.0.0055; confirm the exact version before applying detections to avoid false positives on patched versions. ↗
