| Component | Risk | |-----------|------| | PHP 7.4.6 | Known CVEs (e.g., mail() overflow, phpinfo() leaks) | | phpMyAdmin | Default /phpmyadmin with no password → RCE via SQL or upload | | MySQL | root with no password | | WebDAV | Enabled in some older versions → PUT method uploads | | Directory traversal | ../../ in URL due to misconfigured Alias | | XAMPP’s control panel | Local privilege escalation if run as admin | xampp for windows 746 exploit
If you are using XAMPP as a public server (not recommended), edit the following files:
Older XAMPP versions allowed access to phpMyAdmin without a password or with the default root/blank password. The exploit script sends: GET /phpmyadmin/index.php HTTP/1.1 If the setup is vulnerable, the attacker executes SELECT "<?php system($_GET['cmd']); ?>" INTO OUTFILE "C:/xampp/htdocs/shell.php" .

To secure a XAMPP 7.4.6 installation, follow these steps immediately:
The term "xampp for windows 746 exploit" serves as a valuable case study in the lifecycle of software vulnerabilities. It highlights how a developer's tool, designed for convenience, can become a significant security liability when not properly managed. The privilege escalation flaw in XAMPP 7.4.6 is a reminder that even simple configuration oversights—like a writable .ini file—can have catastrophic consequences. The exploit script sends: GET /phpmyadmin/index
: The attacker then saves the modified xampp-control.ini file and waits. Their malicious file has been configured to execute whenever any user, particularly an admin, views a log file from the XAMPP control panel.
By default, XAMPP is configured to launch notepad.exe to display these logs (XAMPP Arbitrary Code Execution Vulnerability).
: XAMPP is frequently criticized for running services like Apache under the nt authority\system account by default, which grants any successfully exploited service full control over the host system. Mitigation & Recommendations
