CVE-2018-13981: Zeta-Producer Zeta Producer Desktop CMS

Critical severity, CVSS 9.8. EPSS: 17.1% chance of exploitation in the next 30 days.

The websites that were built from Zeta Producer Desktop CMS before 14.2.1 are vulnerable to unauthenticated remote code execution due to a default component that permits arbitrary upload of PHP files, because the formmailer widget blocks .php files but not .php5 or .phtml files. This is related to /assets/php/formmailer/SendEmail.php and /assets/php/formmailer/functions.php.

Affected products

• Zeta-Producer Zeta Producer Desktop CMS: before 14.2.1 (fixed in 14.2.1)
