CVE-2024-6554 in Branda Plugin
Summary
by MITRE • 07/11/2024
The Branda – White Label WordPress, Custom Login Page Customizer plugin for WordPress is vulnerable to Full Path Disclosure in all versions up to, and including, 3.4.18. This is due the plugin utilizing composer without preventing direct access to the files. 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-2024-6554 affects the Branda – White Label WordPress plugin, specifically targeting versions up to and including 3.4.18. This issue represents a critical exposure in web application security architecture where the plugin fails to properly restrict access to its underlying file structure. The vulnerability manifests through the plugin's improper handling of composer dependencies and file access controls, creating an unintended pathway for information disclosure that significantly impacts the security posture of WordPress installations.
This Full Path Disclosure vulnerability occurs when the plugin's implementation allows direct access to its internal files through the web server without proper access controls or sanitization measures. The flaw exists in the plugin's architecture where composer-managed dependencies are accessible via direct URL requests, enabling attackers to traverse the file system and obtain sensitive path information. The vulnerability operates under CWE-200, which specifically addresses information exposure through improper error handling or direct file access, making it particularly dangerous in environments where such information can be leveraged for subsequent attacks.
The operational impact of this vulnerability extends beyond simple information disclosure, as it provides attackers with crucial system information that can be used to craft more sophisticated attacks against the affected WordPress installation. While the path disclosure alone may not directly compromise the system, it serves as a foundational element for attackers to better understand the target environment. The information revealed can be combined with other vulnerabilities to enable more effective exploitation techniques, particularly when combined with path traversal or directory listing vulnerabilities. This makes the vulnerability particularly dangerous in multi-layered attack scenarios where attackers can use the disclosed paths to target specific system components.
Security professionals should recognize this vulnerability as a critical component of the attack surface that requires immediate attention and remediation. The flaw demonstrates poor secure coding practices in the plugin's file access control implementation and represents a failure to properly isolate internal dependencies from public web access. Organizations should implement immediate mitigations including restricting direct access to plugin directories, implementing proper .htaccess rules, or removing vulnerable plugin versions entirely. The vulnerability aligns with ATT&CK technique T1068 which involves exploiting legitimate credentials and access to gain access to systems, where path disclosure can serve as a reconnaissance step in broader attack campaigns. This vulnerability also underscores the importance of proper dependency management and access control configuration in WordPress plugin security, as the issue stems directly from improper implementation of composer-based package handling without adequate security controls.
