Newsletter 漏洞列表

WordPress Email Subscribers & Newsletters plugin before 4.2.3 is susceptible to arbitrary file retrieval via a flaw that allows unauthenticated file download and user information disclosure. An attacker can obtain sensitive information, modify data, and/or execute unauthorized administrative operations.

The Newsletter WordPress plugin before 7.4.5 does not sanitize and escape the $_SERVER['REQUEST_URI'] before echoing it back in admin pages. Although this uses addslashes, and most modern browsers automatically URLEncode requests, this is still vulnerable to Reflected XSS in older browsers such as Internet Explorer 9 or below.

The plugin does not escape generated URLs before outputting them in attributes, leading to Reflected Cross-Site Scripting which could be used against high privilege users such as administrators
