# Exploit Title: ResidenceCMS <= 2.10.1 Stored Cross-Site Scripting via Content Form # Date: 8-7-2024 # Category: Web Application # Exploit Author: Jeremia Geraldi Sihombing # Version: 2.10.1 # Tested on: Windows # CVE: CVE-2024-39143 Description: ---------------- A stored cross-site scripting (XSS) vulnerability exists in ResidenceCMS 2.10.1 that allows a low-privilege user to create malicious property content with HTML inside it, which acts as a stored XSS payload. If this property page is visited by anyone including the administrator, then the XSS payload will be triggered.. Steps to reproduce ------------------------- 1. Login as a low privilege user with property edit capability. 2. Create or Edit one of the user owned property (We can user the default property owned by the user). 3. Fill the content form with XSS payload using the Code View feature. Before saving it make sure to go back using the usual view to see if the HTML is rendered or not. Vulnerable parameter name: property[property_description][content] Example Payload: <img src="x" onerror="alert(document.cookie)"> 4. After saving the new property content and clicking the 'Finish Editing', go to the page and see the XSS is triggered. It is possible to trigger the XSS by using any account or even unauthorized account.
