Technical Details for CVE-2024-30508
Vulnerability Analysis
This vulnerability stems from missing authorization checks within the WP Hotel Booking plugin. The affected plugin fails to properly verify that users have appropriate permissions before allowing access to certain functionality. This type of Broken Access Control vulnerability allows unauthorized users to perform actions or access data that should be restricted to authenticated users with specific roles or privileges.
The vulnerability is exploitable remotely over the network without requiring any user interaction. An attacker does not need valid credentials or elevated privileges to exploit this flaw, making it particularly dangerous for public-facing WordPress installations utilizing this hotel booking solution.
Root Cause
The root cause of CVE-2024-30508 is the absence of proper authorization checks (CWE-862: Missing Authorization) in the WP Hotel Booking plugin. The plugin exposes functionality without validating whether the requesting user has the appropriate permissions to perform the requested action. This architectural flaw allows any unauthenticated network attacker to bypass intended access controls and interact with protected features.
Attack Vector
The attack vector for this vulnerability is network-based, requiring no authentication or user interaction. An attacker can craft requests to the vulnerable WordPress installation that target the unprotected endpoints or functionality within the WP Hotel Booking plugin. Since no authorization checks are in place, these requests are processed as if they originated from a legitimate, authorized user.
The vulnerability allows attackers to potentially:
- Access or modify hotel booking data without authorization
- Manipulate booking records and customer information
- Perform administrative actions reserved for privileged users
- Compromise the overall security posture of the WordPress site
Detection Methods for CVE-2024-30508
Indicators of Compromise
- Unexpected modifications to hotel booking records or configurations
- Suspicious HTTP requests targeting WP Hotel Booking plugin endpoints from unauthenticated sources
- Anomalous database queries or changes related to the wp_hotel_booking tables
- Unauthorized access logs showing requests to protected plugin functionality without valid sessions
Detection Strategies
- Monitor WordPress access logs for requests to WP Hotel Booking plugin endpoints without authenticated sessions
- Implement Web Application Firewall (WAF) rules to detect and block suspicious access patterns targeting the plugin
- Enable WordPress audit logging to track changes to booking data and plugin settings
- Review database activity for unauthorized modifications to booking-related tables
Monitoring Recommendations
- Configure real-time alerting for access attempts to WP Hotel Booking administrative functions from unauthenticated users
- Implement file integrity monitoring on the WP Hotel Booking plugin directory
- Monitor for unusual traffic patterns or request volumes targeting the plugin endpoints
