− | ==Overview==
| |
− | | |
− | An open redirect is an application that takes a parameter and redirects a user to the parameter value without any validation. This vulnerability is used in phishing attacks to get users to visit malicious sites without realizing it.

− | ==Avoidance and mitigation ==
| |
− | To avoid the open redirect vulnerability parameters of the application script/program must be validated before sending 302 HTTP code (redirect) to the client browser.
| |
− | | |
− | The server must have a relation of the authorized redirections (i.e. in a database)

− | http://www.vulnerable.com?redirect=http://www.attacker.com

− | The phishing use can be more complex, using complex encoding:
| |
− | | |
− | Real redirect: http://www.vulnerable.com/redirect.asp?=http://www.links.com
