Vulnerability Summary
-
CVE ID: CVE-2023-3211
-
Severity: High (CVSS 3.1 Score: 8.6)
-
Attack Vector: Network
-
Privileges Required: None
-
User Interaction: None
-
Impact: SQL Injection leading to potential data exfiltration or manipulation
Affected Products
The vulnerability affects the WordPress Database Administrator plugin, specifically versions up to and including 1.0.3.
How the Exploit Works
The plugin exposes an AJAX action named wdaSetTableActionResponse that fails to properly sanitize and escape the table parameter. This oversight allows unauthenticated attackers to inject arbitrary SQL queries. For instance, an attacker can exploit this vulnerability by sending a crafted POST request to the admin-ajax.php endpoint:
No phone number, email, or personal info required.
In this example, the injected SLEEP(1) function causes a delay in the server’s response, indicating a successful SQL injection.
Potential Risks
-
Unauthorized access to sensitive data, including user credentials
-
Modification or deletion of database content
-
Potential for full site compromise
-
Use of the site as a pivot point for further attacks
Mitigation Recommendations
-
Immediate Action: If you’re using the affected plugin version, consider disabling or removing it until a patched version is available.
-
Update the Plugin: Regularly check for updates to the plugin and apply them promptly.
-
Implement Web Application Firewalls (WAF): Deploy a WAF to detect and block malicious requests targeting known vulnerabilities.
-
Monitor Logs: Regularly review server and application logs for unusual activities that may indicate exploitation attempts.
Conclusion
CVE-2023-3211 is a critical vulnerability in the WordPress Database Administrator plugin that allows unauthenticated attackers to perform SQL injection attacks. Given the severity and ease of exploitation, it’s imperative to take immediate action to mitigate potential risks.
