Technical description

In PrestaShop between versions 1.7.6.0 and 1.7.6.5, there is an open redirection when using back parameter. The impacts can be many, and vary from the theft of information and credentials to the redirection to malicious websites containing attacker-controlled content, which in some cases even cause XSS attacks. So even though an open redirection might sound harmless at first, the impacts of it can be severe should it be exploitable. The problem is fixed in 1.7.6.5
