Reading a file through path traversal & Remote Code Execution via unsafe deserialization
Initialy flagged as path traversal with a medium severity, the work of Friends Of Presta Security team proven the ability to use this vulnerability to implicity deserialize a malicious load (critical severity).
displayAjaxEmailHTML method can be used to read any file on the server, potentially even outside of the project if the server is not correctly configured.
Moreover, any wrapper like https, ftp, phar, … can be exploited to forge a SSRF (server side request forgery). The ability to use phar:// can be exploited to forge an unserialization as proven in our security research advisory “Exploring the perils of implicit deserialization of a phar in PrestaShop (part 2)”
