The Royal Elementor Addons and Templates WordPress plugin before 1.3.79 does not properly validate uploaded files, which could allow unauthenticated users to upload arbitrary files, such as PHP and achieve RCE. This vulnerability is classified as critical with a CVSS score of 9.8, indicating the potential for severe impact on affected systems.
Organizations using this plugin should be particularly concerned as the exploitation can occur without any user authentication. The risk to organizations includes unauthorized access to sensitive data, system compromise, and potential disruption of service.
Given the high severity and potential for exploitation, organizations should prioritize patching immediately. As of now, there are known exploits available, thus increasing the urgency for remediation efforts.
The CVE was published on October 31, 2023, and has been marked as modified since then, which suggests ongoing attention and updates regarding its impact and remediation.
Vulnerability Details
The vulnerability in question allows for the arbitrary file upload due to inadequate validation of uploaded files by the Royal Elementor Addons and Templates plugin. The CVSS score of 9.8 categorizes it as critical, reflecting its high impact across confidentiality, integrity, and availability.
It is classified under CWE-434, which pertains to the improper handling of file uploads. The affected versions include all versions prior to 1.3.79.
Technical Analysis
The root cause of this vulnerability stems from the lack of proper validation mechanisms in the plugin to verify the type and content of uploaded files. Attackers may leverage this vulnerability through the network, exploiting the low attack complexity and zero privileges required for execution.
No user interaction is required, which further simplifies the exploitation process. The impact on confidentiality, integrity, and availability is significant, as successful exploitation can lead to the execution of arbitrary code on the server.
Risk & Impact Analysis
Real-world deployment of this vulnerability poses a severe risk to organizations, especially those relying on the affected WordPress plugin for their operations. The blast radius for potential exploitation is considerable, given the widespread use of the plugin in various WordPress installations.
Organizations should assess their exposure and prioritize remediation to limit the risk of unauthorized access and potential data breaches. The urgency is underscored by the high CVSS score and the presence of known exploits in the wild.
