Description Laura Pardo 2018-01-16 18:35:56 EST

A flaw was found in php when creating a .phar file and configuring apache to handle phar files using php, when accessing invalid page the page name is reflected back to the user in the 404 response. This user input is not being sanitized and therefore it is vulnerable to a reflected XSS. Making, every site configured to run .phar files using php vulnerable.
