CVE-2024-0867: CWE-94 Improper Control of Generation of Code ('Code Injection') in webfactory Email Log
The Email Log plugin for WordPress is vulnerable to Unauthenticated Hook Injection in all versions up to, and including, 2.4.8 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
The Email Log plugin for WordPress is vulnerable to unauthenticated hook injection due to improper control in the check_nonce function. An attacker who knows a valid nonce and targets an action hook without capability checks can execute arbitrary actions within WordPress. This vulnerability is classified as CWE-94 (Improper Control of Generation of Code) and affects all versions up to and including 2.4.8. The CVSS 3.1 base score is 8.1, reflecting a network attack vector with high impact on confidentiality, integrity, and availability, and requiring high attack complexity but no privileges or user interaction.
Potential Impact
Successful exploitation allows unauthenticated attackers to execute arbitrary actions via WordPress hooks, potentially leading to code injection and full compromise of the affected WordPress site. The impact includes complete loss of confidentiality, integrity, and availability of the site and its data.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict access to the affected plugin and monitor for suspicious activity. Avoid exposing nonces publicly and ensure that all action hooks implement proper capability checks. Follow vendor updates closely for an official patch or temporary mitigations.
