Description Preview
MiniCMS version 1.10 contains a Cross-Site Scripting (XSS) vulnerability that allows attackers to execute arbitrary code through crafted GET requests. This vulnerability can be exploited to inject malicious scripts that execute in the context of other users' browsers, potentially leading to session hijacking, credential theft, or other client-side attacks.
Overview
This vulnerability (CVE-2021-33387) is classified as CWE-79 (Cross-site Scripting) and affects MiniCMS version 1.10. The issue occurs because the application fails to properly validate and sanitize user-supplied input before including it in web pages. Attackers can exploit this by crafting special GET requests containing malicious JavaScript code that will be executed when viewed by other users. Successful exploitation could allow attackers to steal cookies, session tokens, or other sensitive information, perform actions on behalf of the victim, or modify the appearance of the web page.
Remediation
To address this vulnerability, system administrators and developers should:
- Update MiniCMS to a version that fixes this vulnerability if available
- Implement proper input validation and output encoding for all user-supplied data
- Consider implementing Content Security Policy (CSP) headers to mitigate XSS attacks
- Validate all input parameters and sanitize them before processing
- Apply the principle of least privilege for all web application components
- Monitor application logs for suspicious activities that might indicate exploitation attempts
