sNews is prone to multiple input-validation vulnerabilities. These issues are due to a failure in the application to properly sanitize user-supplied input.
 
Successful exploitation of these vulnerabilities could allow an attacker to compromise the application, access or modify data, steal cookie-based authentication credentials, control how the site is rendered to the user, or exploit vulnerabilities in the underlying database implementation. Other attacks are possible as well.
