A path traversal vulnerability exists in the Java version of CData API Server < 23.4.8844 when running using the embedded Jetty server, which could allow an unauthenticated remote attacker to gain com

The path traversal vulnerability in CData API Server allows an attacker to bypass access controls and manipulate file paths. By crafting malicious requests, an attacker can read arbitrary files on the server, potentially including sensitive configuration data, credentials, or proprietary source code. The ability to gain administrative access means the attacker could modify system settings, create new users with elevated privileges, or even execute arbitrary code on the server. This represents a significant risk, particularly if the API Server handles sensitive data or integrates with other critical systems. Successful exploitation could lead to complete system takeover and data exfiltration.

Organizations deploying CData API Server in Java environments, particularly those with exposed API endpoints or limited network segmentation, are at significant risk. Shared hosting environments where multiple users share the same server instance are also vulnerable, as an attacker could potentially exploit the vulnerability to compromise other users' data.

• java / server: Monitor access logs for requests containing path traversal sequences (e.g., '../'). • generic web: Use curl to test for path traversal vulnerabilities by attempting to access files outside the intended directory structure. Example:

curl 'http://your-api-server/../../../../etc/passwd'

• generic web: Check response headers for unexpected file disclosures. • linux / server: Examine system logs for unusual file access patterns or unauthorized modifications.

The primary mitigation for CVE-2024-31848 is to immediately upgrade CData API Server to version 23.4.8844 or later. If upgrading is not immediately feasible, consider implementing temporary workarounds such as restricting network access to the API Server to only trusted sources. Deploying a Web Application Firewall (WAF) with rules to block path traversal attempts (e.g., filtering for '../' sequences in requests) can provide an additional layer of defense. Regularly review and harden the server's configuration, ensuring that unnecessary services are disabled and file permissions are properly restricted. After upgrading, confirm the fix by attempting a path traversal request and verifying that access is denied.
