CVE-2024-0866: CWE-94 Improper Control of Generation of Code ('Code Injection') in checkemail Check & Log Email – Easy Email Testing & Mail logging
The Check & Log Email plugin for WordPress is vulnerable to Unauthenticated Hook Injection in all versions up to, and including, 1.0.9 via the check_nonce function. This makes it possible for unauthenticated attackers to execute actions with hooks in WordPress under certain circumstances. The action the attacker wishes to execute needs to have a nonce check, and the nonce needs to be known to the attacker. Furthermore, the absence of a capability check is a requirement.
AI Analysis
Technical Summary
CVE-2024-0866 describes an unauthenticated hook injection vulnerability in the Check & Log Email WordPress plugin (up to version 1.0.9). The vulnerability arises from improper validation in the check_nonce function, enabling attackers without authentication to trigger WordPress actions that rely on hooks, provided the action requires a nonce check and the nonce is known. The absence of capability checks further facilitates exploitation. This vulnerability is categorized under CWE-94, indicating improper control over code generation, and carries a high impact on confidentiality, integrity, and availability as reflected by its CVSS 3.1 score of 8.1.
Potential Impact
Successful exploitation could allow unauthenticated attackers to execute arbitrary actions within WordPress via hooks, potentially leading to full compromise of confidentiality, integrity, and availability of the affected system. The high CVSS score (8.1) indicates a significant risk. However, exploitation requires knowledge of a valid nonce and the targeted action must lack proper capability checks.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, administrators should consider disabling or removing the Check & Log Email plugin if it is not essential. Monitoring for plugin updates and applying any forthcoming patches promptly is recommended. No vendor advisory or official patch information is currently provided, so follow vendor channels for updates.
