CVE-2024-6571 in Optimize Images ALT Text & Names for SEO using AI Plugin
Summary
by MITRE • 07/24/2024
The Optimize Images ALT Text (alt tag) & names for SEO using AI plugin for WordPress is vulnerable to Full Path Disclosure in all versions up to, and including, 3.1.1. This is due the plugin utilizing cocur and not preventing direct access to the generate-default.php file. This makes it possible for unauthenticated attackers to retrieve the full path of the web application, which can be used to aid other attacks. The information displayed is not useful on its own, and requires another vulnerability to be present for damage to an affected website.

The vulnerability identified as CVE-2024-6571 affects the Optimize Images ALT Text plugin for WordPress, specifically targeting versions up to and including 3.1.1. This issue manifests as a Full Path Disclosure vulnerability that stems from the plugin's improper handling of file access through its dependency on the cocur library. The flaw occurs when the plugin allows direct access to the generate-default.php file without proper access controls or authentication checks, creating an avenue for attackers to obtain sensitive server path information.
The technical implementation of this vulnerability involves the plugin's failure to properly validate or restrict access to internal script files that should not be directly accessible via web requests. When an attacker accesses the generate-default.php file directly, the system reveals the complete server path structure to the web application, including directory names and file locations. This type of information disclosure aligns with CWE-209, which specifically addresses the exposure of system information through error messages or direct file access. The vulnerability operates at the application level and demonstrates poor input validation and access control mechanisms that are fundamental to secure web application design.
The operational impact of this vulnerability, while not immediately exploitable on its own, creates significant risks for affected WordPress installations. The disclosed path information can serve as valuable reconnaissance data for attackers planning more sophisticated attacks, as it provides insights into the server configuration and file structure. This information can be leveraged in conjunction with other vulnerabilities to facilitate more targeted attacks, potentially enabling attackers to bypass security measures or exploit additional weaknesses in the system. The vulnerability affects the plugin's security posture by exposing internal application architecture details that should remain hidden from external parties, thereby reducing the overall security surface.
Security professionals should consider this vulnerability in the context of the ATT&CK framework, particularly under the reconnaissance phase where attackers gather system information before executing more invasive attacks. The full path disclosure can be categorized as a reconnaissance technique that provides attackers with critical infrastructure information. Organizations should implement immediate mitigations including restricting direct access to plugin files through web server configurations, updating to patched versions when available, and implementing proper access controls that prevent unauthorized access to internal application components. Additionally, regular security audits and monitoring of web application logs should be conducted to detect potential exploitation attempts targeting such vulnerabilities. The vulnerability demonstrates the importance of proper file access controls and the principle of least privilege in web application security design.
