In the domain of website development, the usage of plugins extends the functionality of platforms, such as WordPress. However, these plugins can also introduce security vulnerabilities. Recently, the Wordfence Threat Intelligence team issued a warning about ongoing attacks exploiting a zero-day vulnerability found in the Royal Elementor Addons and Templates plugin. This vulnerability allows unauthorized users to upload arbitrary files and execute remote code on affected websites. This article aims to dissect this issue in detail and offer concrete recommendations for those affected.
The Genesis of the Problem: What is a Zero-Day?
In the cybersecurity realm, a zero-day vulnerability refers to a software flaw that is exploited before a fix is released by the vendor. This situation gives website administrators little to no time to protect their websites, making the vulnerability particularly dangerous. In this case, the flaw was in the Royal Elementor Addons and Templates plugin, commonly known as ‘WP Royal.’
Risk Assessment: CVE and CVSSv3 Scoring
Understanding the severity of this vulnerability involves interpreting its Common Vulnerabilities and Exposures Identifier (CVE-ID) and Common Vulnerability Scoring System (CVSS) score. The CVE-ID for this vulnerability is CVE-2023-5360 and it has been assigned a CVSSv3 score of 9.8. In the CVSS scoring system, a score above 9 is considered critical, signaling the immediate need for action to mitigate the associated risks.
Technical Specifics: How the Vulnerability Works
The Royal Elementor Addons and Templates plugin is designed to simplify the web development process by enabling the easy creation of web elements. The plugin does possess a feature for validating file extensions to restrict uploads to authorized file types only. However, this vulnerability enables attackers to bypass this restriction by manipulating the ‘allowed list.’ This loophole could lead to remote code execution and potentially result in the full compromise of the website.
Real-world Impact: Recent Exploits and Payloads
Reports from two notable WordPress security firms, Wordfence and WPScan, have confirmed active exploitation of this vulnerability. Specifically, since August 30, 2023, Wordfence has blocked over 46,000 attacks targeting Royal Elementor, while WPScan recorded 889 instances involving ten distinct payloads. Most payloads are PHP scripts aimed at either creating a WordPress administrator user named ‘wordpress_administrator’ or acting as a backdoor.
Mitigation Steps: What You Can Do Right Now
Users of the Royal Elementor Addons and Templates plugin are strongly advised to upgrade to the latest version (1.3.79) as soon as possible. Additionally, running a malware scan using Wordfence CLI or the Wordfence plugin can help confirm whether a site has been compromised. If commercial scanning solutions are not accessible, a free scanner can also be used to assess your website’s security status. Note that updating to the latest version will not remove existing malware or malicious files; thus, manual website cleanup is essential.
Final Thoughts
This article aimed to provide a detailed explanation of the recent zero-day vulnerability affecting the Royal Elementor Addons and Templates plugin for WordPress. With the risk being severe, as indicated by the CVSSv3 score of 9.8, immediate action is crucial. Adhering to the recommendations could prevent your website from becoming another statistic in the list of compromised platforms.
