[-] Vulnerability Description:
|
|
|
|
User input passed through the "url" request parameter to the /core/redirect route is
|
|
not properly sanitized before being used in a call to the unserialize() PHP function.
|
|
This can be exploited by remote, unauthenticated attackers to inject arbitrary PHP
|
|
objects into the application scope, allowing them to perform a variety of attacks,
|
|
such as executing arbitrary PHP code.
|
|
