CVE-2024-4382 in CB Plugin
Summary
by MITRE • 06/21/2024
The CB (legacy) WordPress plugin through 0.9.4.18 does not have CSRF checks in some bulk actions, which could allow attackers to make logged in admins perform unwanted actions, such as deleting codes, timeframes, and bookings via CSRF attacks

The CB legacy WordPress plugin version 0.9.4.18 and earlier contains a critical Cross-Site Request Forgery vulnerability that compromises the security of administrative users. This vulnerability stems from the absence of proper CSRF protection mechanisms within specific bulk action functionalities of the plugin. The flaw allows authenticated attackers to manipulate administrative users into executing unintended operations without their knowledge or consent. The affected plugin's administrative interface lacks the necessary anti-CSRF tokens or validation checks that would normally prevent unauthorized requests from being processed on behalf of legitimate administrators.
The technical implementation of this vulnerability occurs when administrators access maliciously crafted web pages or click on compromised links while logged into their WordPress admin dashboard. The plugin's bulk action handlers do not validate the origin of requests or verify that the actions were intentionally initiated by the logged-in user. This absence of request validation creates an exploitable condition where attackers can craft HTTP requests that appear legitimate to the WordPress plugin's backend processing logic. The vulnerability specifically targets administrative functions related to code management, timeframe configuration, and booking operations, making it particularly dangerous for businesses that rely on the plugin for scheduling and resource management.
The operational impact of this vulnerability extends beyond simple unauthorized modifications to critical business data. Attackers can exploit this weakness to delete important scheduling information, manipulate booking records, and potentially disrupt service operations. The compromised administrative sessions provide attackers with elevated privileges that could lead to further system compromise or data exfiltration. This vulnerability particularly affects organizations that depend on the plugin for time-based resource allocation, appointment scheduling, or code management systems where unauthorized deletions could result in significant operational disruption. The risk is amplified because the vulnerability does not require authentication from the attacker's perspective, as the attack leverages the existing administrative session.
Security professionals should immediately implement mitigations including applying the latest plugin updates if available, implementing additional CSRF protection layers, and reviewing administrative session management practices. Organizations should consider deploying web application firewalls that can detect and block suspicious bulk action requests, while also ensuring proper input validation and origin checking mechanisms are in place. The vulnerability aligns with CWE-352 which specifically addresses Cross-Site Request Forgery weaknesses, and maps to ATT&CK technique T1566.002 for phishing attacks that leverage CSRF vulnerabilities. Regular security audits should verify that all administrative interfaces implement proper CSRF protection mechanisms, and that bulk operations require explicit user confirmation or token validation to prevent unauthorized execution of administrative tasks.
