CVE-2024-47769: Path Traversal in IDURAR ERP CRM

The core of the vulnerability lies within the corePublicRouter.js file, where user input is directly appended to a join statement without proper validation. This lack of sanitization enables an attacker to craft malicious, URL-encoded payloads that bypass intended directory restrictions. By strategically encoding path traversal sequences (e.g., ../..), an attacker can navigate the file system and access files outside of the intended scope. The potential impact includes exposure of configuration files, source code, and potentially sensitive data stored on the server. Successful exploitation could lead to complete compromise of the system, depending on the permissions of the web server user.

The primary mitigation for CVE-2024-47769 is to immediately upgrade IDURAR ERP CRM to version 4.1.1 or later, which contains the necessary fix. If upgrading is not immediately feasible, consider implementing a Web Application Firewall (WAF) with rules to block requests containing suspicious path traversal patterns (e.g., ../, encoded equivalents). Additionally, restrict file system permissions for the web server user to the absolute minimum required for operation. Monitor access logs for unusual file access attempts that might indicate exploitation. After upgrade, confirm by attempting to access a sensitive file via a crafted path traversal URL; the request should be denied.
