Description Preview
A cross-site scripting (XSS) vulnerability exists in DynPG version 4.9.2 that allows remote attackers to inject malicious JavaScript code through the "query" parameter. This vulnerability could enable attackers to execute arbitrary JavaScript in the context of the victim's browser, potentially leading to cookie theft, session hijacking, or other client-side attacks.
Overview
DynPG version 4.9.2 is affected by a reflected cross-site scripting vulnerability (CWE-79). The application fails to properly sanitize user input provided through the "query" parameter before reflecting it back in the response. This allows attackers to craft malicious URLs containing JavaScript code that executes when a victim clicks on the link or visits the manipulated page. The vulnerability could lead to unauthorized access to sensitive information, session hijacking, phishing attacks, or defacement of the affected web application.
Remediation
Organizations using DynPG 4.9.2 should implement the following remediation steps:
- Update to the latest version of DynPG if a patched version is available.
- If updates are not immediately available, implement proper input validation and output encoding for the "query" parameter.
- Consider implementing Content Security Policy (CSP) headers to mitigate the impact of XSS vulnerabilities.
- Apply the principle of least privilege to web application accounts and services.
- Regularly audit and test web applications for security vulnerabilities, particularly focusing on input validation and output encoding.
