CVE-2024-5329 identifies a blind SQL Injection vulnerability in the Unlimited Elements For Elementor plugin for WordPress, specifically in versions up to and including 1.5.109. The vulnerability stems from insufficient escaping and lack of proper preparation of the 'data[addonID]' parameter within SQL queries. Authenticated attackers with Contributor-level privileges or higher can exploit this flaw by injecting additional SQL commands into existing queries. This injection allows attackers to extract sensitive information from the backend database, potentially including user data, configuration details, or other confidential content. The vulnerability does not require user interaction but does require authentication, which lowers the barrier compared to administrator-only exploits. The CVSS 3.1 base score of 8.8 reflects the vulnerability's high impact on confidentiality, integrity, and availability, with network attack vector, low attack complexity, and privileges required. Although no known public exploits are reported yet, the vulnerability's nature and ease of exploitation make it a critical concern for WordPress sites using this plugin. The plugin is widely used in the WordPress ecosystem, especially among sites leveraging Elementor for page building, increasing the potential attack surface. The vulnerability is categorized under CWE-89, indicating improper neutralization of special elements in SQL commands, a common and dangerous injection flaw. No official patches or updates are linked yet, so mitigation may require temporary workarounds or access restrictions until a fix is released.

The impact of CVE-2024-5329 is significant for organizations running WordPress sites with the Unlimited Elements For Elementor plugin installed. Successful exploitation can lead to unauthorized disclosure of sensitive database contents, including user credentials, personal data, and site configuration. This compromises confidentiality and can facilitate further attacks such as privilege escalation or site takeover. Integrity is at risk as attackers might modify database entries, potentially defacing websites or injecting malicious content. Availability could also be affected if injected queries disrupt normal database operations or cause crashes. Since the vulnerability requires only Contributor-level access, attackers can leverage compromised or malicious user accounts to escalate their impact. This broadens the threat beyond just administrators, increasing the risk in multi-user environments. The absence of known exploits in the wild currently reduces immediate risk, but the high CVSS score and ease of exploitation mean attackers may develop exploits rapidly. Organizations face reputational damage, legal liabilities under data protection regulations, and operational disruptions if this vulnerability is exploited. The widespread use of WordPress and Elementor in various sectors, including e-commerce, media, and corporate websites, amplifies the global risk.

To mitigate CVE-2024-5329, organizations should first verify if they use the Unlimited Elements For Elementor plugin and identify the version in use. Immediate steps include restricting Contributor-level user permissions to trusted individuals only, minimizing the risk of exploitation from compromised accounts. Implementing Web Application Firewalls (WAFs) with custom rules to detect and block suspicious SQL injection patterns targeting the 'data[addonID]' parameter can provide temporary protection. Monitoring database query logs for unusual or unexpected queries may help detect exploitation attempts early. Until an official patch is released, consider disabling or removing the plugin if feasible, especially on high-risk or sensitive sites. Site administrators should enforce strong authentication and consider multi-factor authentication to reduce account compromise risk. Regular backups of the database and site files are essential to enable recovery in case of successful exploitation. Stay informed through vendor announcements and security advisories to apply patches promptly once available. Additionally, developers and security teams should review custom code interacting with this plugin to ensure no additional injection vectors exist.
