CVE-2020-13125 Scanner

The Ultimate Addons for Elementor is a WordPress plugin used to enhance web design capabilities by adding additional widgets and features to the Elementor page builder. Website developers and designers commonly employ it to create visually appealing, customizable, and functional websites. It is particularly popular among WordPress users aiming to improve website interactivity without complex coding. Businesses and individuals use this plugin to develop engaging websites that cater to various digital experiences. Its integration with Elementor makes it an essential tool for expanding design possibilities on WordPress websites. However, maintaining robust security measures is crucial given the susceptibility to unauthorized access vulnerabilities.

The vulnerability within the Ultimate Addons for Elementor plugin potentially allows unauthenticated attackers to bypass standard registration processes and create user accounts with Subscriber roles. Such vulnerability may lead to unauthorized users gaining access to protected site functionalities. Exploitation of this issue particularly affects sites with registration disabled, as attackers can create accounts unnoticed. This security flaw has been widely acknowledged in previous incidents, and its impact can extend to further privilege escalation attempts. Consequently, ensuring the plugin's security integrity is paramount to prevent potential misuses. Addressing this vulnerability promptly by updating affected versions is critical for site security.

From a technical standpoint, the vulnerability is exploited via specific endpoints like "/wp-admin/admin-ajax.php" and involves unauthorized user registration. Attackers utilize POST requests to inject parameters like form_nonce and widget_id to bypass the defensive barriers. Parameter manipulation leads to unexpected user account creation beyond intended permissions. Identifying vulnerable endpoints and applying stringent input validations can mitigate this threat. The vulnerability is often exacerbated when default security configurations are not modified. Keeping site plugins updated and applying consistent security patches significantly reduce exploitation risks.

Exploiting this vulnerability can have severe repercussions, ranging from data breaches to complete site hijacking. Unauthorized user account creation may eventually lead to privilege escalation, permitting attackers access to sensitive areas within a WordPress site. It enhances the risk of further attacks like cross-site scripting or SQL injection due to additional entry points. Malicious actors could propagate spam or malware across compromised sites, affecting their reputation. Ignoring this issue may also enable attackers to gain administrator access, damaging critical infrastructure. Consequently, immediate remediation is necessary to avert detrimental consequences.
