Unrestricted Access and Cross-Site Scripting (XSS) Vulnerability in MailUp Plugin for WordPress

CVE-2013-0731 · MEDIUM Severity

AV:N/AC:L/AU:N/C:N/I:P/A:N

ajax.functions.php in the MailUp plugin before 1.3.3 for WordPress does not properly restrict access to unspecified Ajax functions, which allows remote attackers to modify plugin settings and conduct cross-site scripting (XSS) attacks by setting the wordpress_logged_in cookie. NOTE: this is due to an incomplete fix for a similar issue that was fixed in 1.3.2.
