WebTester is prone to multiple input-validation issues, including multiple cross-site scripting and multiple SQL-injection issues, 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 even exploit vulnerabilities in the underlying database implementation. Other attacks are also possible.

WebTester 5.0.20060927 and prior versions are vulnerable.
