Description Preview
A cross-site scripting (XSS) vulnerability has been identified in YzmCMS version 5.3. The vulnerability exists in the /banner/add.html component, which fails to properly sanitize user input. This vulnerability allows attackers to inject and execute arbitrary web scripts or HTML code in the context of a victim's browser session, potentially leading to cookie theft, session hijacking, credential harvesting, or other malicious actions.
Overview
YzmCMS v5.3 contains a cross-site scripting vulnerability (CWE-79) in its banner management functionality. When a user accesses the /banner/add.html component, malicious actors can inject JavaScript or HTML code that will be executed in the victim's browser. This vulnerability occurs because the application does not properly validate, filter, or encode user-supplied input before including it in the output page. Successful exploitation could allow attackers to steal sensitive information, manipulate content, redirect users to malicious websites, or perform actions on behalf of the victim user within the application.
Remediation
To address this vulnerability, system administrators and developers should:
- Update YzmCMS to the latest version if a patch is available
- Implement proper input validation and output encoding in the banner component
- Consider implementing Content Security Policy (CSP) headers to mitigate XSS attacks
- Review and sanitize all user inputs, especially in the banner management functionality
- Apply the principle of least privilege to administrative accounts that can access the banner functionality
- Regularly monitor application logs for potential XSS attack attempts
