A user with elevated privileges could upload a photo to the system in an SVG format. This file will be uploaded to the system and it will not be stripped or filtered. The user can create a link on the website pointing to "/storage/poc.svg" that will point to http://localhost/pagekit/storage/poc.svg. When a user comes along to click that link, it will trigger a XSS attack. ### POC #### Reference - http://ruffsecurity.blogspot.com/2018/05/my-first-cve-found.html - https://packetstormsecurity.com/files/148001/PageKit-CMS-1.0.13-Cross-Site-Scripting.html - https://www.exploit-db.com/exploits/44837/ #### Github - https://github.com/0xT11/CVE-POC - https://github.com/GeunSam2/CVE-2018-11564
