CVE-2024-58283: HIGH Severity Remote Code Execution in WBCE CMS | Secably CVE Database

Summary

CVE-2024-58283 is a critical remote code execution (RCE) vulnerability affecting WBCE CMS version 1.6.2. This vulnerability allows authenticated attackers to upload malicious PHP files through the Elfinder file manager, leading to arbitrary code execution on the server.

Technical Details

CVE-2024-58283 arises from insufficient input validation within the Elfinder file manager component of WBCE CMS 1.6.2. Authenticated users with appropriate permissions can leverage the file upload functionality in the Elfinder connector to upload arbitrary files, including PHP scripts. By uploading a specially crafted PHP file (a web shell), an attacker can then execute arbitrary system commands on the server. The vulnerability stems from the lack of proper checks on the file extension and content during the upload process. The Elfinder connector processes the uploaded file without adequate sanitization, allowing the malicious PHP code to be executed by the web server. Successful exploitation grants the attacker the same privileges as the web server user, potentially leading to full system compromise.

The attack vector involves first authenticating to the WBCE CMS application. Then, the attacker navigates to the Elfinder file manager interface, typically accessible through the backend administration panel. Using the file upload functionality, the attacker uploads a PHP file containing malicious code. Finally, the attacker accesses the uploaded PHP file through a web browser, triggering the execution of the malicious code on the server.

Affected Products and Versions

WBCE CMS version 1.6.2

Impact Assessment

Successful exploitation of CVE-2024-58283 can have severe consequences, including complete compromise of the WBCE CMS server. An attacker can gain unauthorized access to sensitive data, modify website content, install malware, and potentially pivot to other systems on the network.

Data breach risk: Sensitive data stored within the WBCE CMS database, such as user credentials and customer information, could be exposed.
System compromise: The attacker can gain full control of the web server, allowing them to execute arbitrary commands and potentially compromise other systems on the network.
Website defacement: The attacker can modify website content, deface the website, or inject malicious code into the website's pages.
Malware distribution: The attacker can use the compromised server to host and distribute malware to website visitors.

Remediation

Immediate Actions

Upgrade WBCE CMS: Upgrade to a patched version of WBCE CMS that addresses this vulnerability. Check the official WBCE CMS website for updates.
Restrict File Upload Permissions: Review and restrict file upload permissions within the Elfinder file manager to only authorized users.
Monitor System Logs: Monitor system logs for suspicious activity, such as unauthorized file uploads or execution of unusual processes.

Long-term Solutions

Implement Input Validation: Implement robust input validation and sanitization for all file uploads, including file extension and content checks.
Regular Security Audits: Conduct regular security audits and penetration testing to identify and address potential vulnerabilities.
Web Application Firewall (WAF): Deploy a web application firewall (WAF) to detect and block malicious file uploads and other attacks.
