Extended Description
Attackers can easily modify cookies, within the browser or by implementing the client-side code outside of the browser. Reliance on cookies without detailed validation and integrity checking can allow attackers to bypass authentication, conduct injection attacks such as SQL injection and cross-site scripting, or otherwise modify inputs in unexpected ways.
Example - 1
The following code excerpt reads a value from a browser cookie to determine the role of the user. It is easy for an attacker to modify the "role" value found in the locally stored cookie, allowing privilege escalation.
userRole = c.getValue();Cookie c = cookies[i];if (c.getName().equals("role")) {}Cookie[] cookies = request.getCookies();for (int i =0; i< cookies.length; i++) {}
