Vulnerability Overview
The Countdown and CountUp, WooCommerce Sales Timers WordPress plugin is vulnerable to Cross-Site Request Forgery via the save_theme function found in the ~/includes/admin/coundown_theme_page.php file due to a missing nonce check which allows attackers to inject arbitrary web scripts, in versions up to and including 1.5.7.

CWE-352: Cross-Site Request Forgery (CSRF)
Reaching this weakness in Countdown and CountUp, WooCommerce Sales Timer <= 1.5.7 takes a caller who can reach the endpoint. Cross-site request forgery abuses the fact that browsers attach a victim's cookies to any request, so a state-changing action that only checks who you are, not whether you meant to act, can be triggered from another site.
An attacker who gets a logged-in user to load a crafted page can perform that action as them, with the impact scaling to whatever the victim's role is allowed to do. For Countdown and CountUp, WooCommerce Sales Timer the fix is 1.5.8: builds <= 1.5.7 are affected, anything from 1.5.8 onward is not.
Remediation
Update to version 1.5.8, or a newer patched version
