Overview<\/strong><\/p>\n

A critical vulnerability, identified as CVE-2023-6751, has been discovered in the Hostinger plugin for WordPress. This vulnerability affects all versions up to and including 1.9.7 of the plugin. The vulnerability allows unauthenticated attackers to manipulate plugin settings, potentially leading to system compromise or data leakage. It is therefore crucial for users and administrators of WordPress sites running the Hostinger plugin to take immediate action to mitigate this risk.<\/p>\n

Vulnerability Summary<\/strong><\/p>\n

CVE ID: CVE-2023-6751
\nSeverity: High (7.3 CVSS Score)
\nAttack Vector: Network
\nPrivileges Required: None
\nUser Interaction: None
\nImpact: Unauthorized settings update leading to potential system compromise or data leakage<\/p>\n

Affected Products<\/strong><\/p>\n

Product | Affected Versions<\/p>\n

Hostinger Plugin for WordPress | Up to and including 1.9.7<\/p>\n

How the Exploit Works<\/strong><\/p>\n

The exploit leverages a missing capability check in the function publish_website within the Hostinger plugin for WordPress. An attacker can send a specially crafted request to this function, which would then allow them to manipulate the plugin’s settings, including enabling or disabling maintenance mode, without requiring any form of authentication.<\/p>\n

Conceptual Example Code<\/strong><\/p>\n

This is a
\nconceptual<\/strong>
\n example of how the vulnerability might be exploited. It represents a hypothetical HTTP request to the vulnerable endpoint:<\/p>\n

POST \/wp-admin\/admin-ajax.php?action=hostinger_publish_website HTTP\/1.1\nHost: target.example.com\nContent-Type: application\/json\n{ \"maintenance_mode\": \"enable\" }<\/code><\/pre>\n
In this example, the attacker is trying to enable the maintenance mode on the target site by sending a malicious JSON payload to the administrative endpoint of the WordPress site.<\/p>\n
Mitigation Guidance<\/strong><\/p>\n
The recommended mitigation strategy is to apply the vendor patch as soon as it becomes available. In the meantime, users can employ a Web Application Firewall (WAF) or Intrusion Detection System (IDS) as a temporary mitigation measure. Regular monitoring of system logs for any suspicious activity is also advised.<\/p>\n","protected":false},"excerpt":{"rendered":"
