CVE-2025-32950 in Jmix
Summary
by MITRE • 04/22/2025
Jmix is a set of libraries and tools to speed up Spring Boot data-centric application development. In versions 1.0.0 to 1.6.1 and 2.0.0 to 2.3.4, attackers could manipulate the FileRef parameter to access files on the system where the Jmix application is deployed, provided the application server has the necessary permissions. This can be accomplished either by modifying the FileRef directly in the database or by supplying a harmful value in the fileRef parameter of the `/files` endpoint of the generic REST API. This issue has been patched in versions 1.6.2 and 2.4.0. A workaround is provided on the Jmix documentation website.

The vulnerability CVE-2025-32950 represents a critical path traversal flaw in the Jmix framework, a Spring Boot-based development toolkit designed to accelerate data-centric application development. This security weakness stems from insufficient input validation and sanitization mechanisms within the file reference handling system, allowing unauthorized attackers to exploit the FileRef parameter in the generic REST API endpoint. The vulnerability affects Jmix versions ranging from 1.0.0 through 1.6.1 and 2.0.0 through 2.3.4, creating a substantial attack surface across multiple framework releases. The flaw specifically enables attackers to manipulate file access paths through direct database modification or by injecting malicious values into the fileRef parameter of the /files endpoint, bypassing normal file access controls.
The technical exploitation of this vulnerability occurs through parameter manipulation techniques that leverage the framework's insufficient validation of user-supplied file reference data. When an attacker submits a crafted FileRef value to the /files endpoint, the application fails to properly sanitize or validate the input, allowing path traversal sequences such as ../ or ..\ to be processed. This creates a condition where the application interprets the malicious input as a legitimate file path, potentially enabling access to sensitive system files, configuration data, or other resources that should remain protected. The vulnerability's impact is amplified by the fact that it requires only minimal privileges to exploit, as the application server already possesses the necessary permissions to access the targeted system files. This aligns with CWE-22, which describes improper limitation of a pathname to a restricted directory, and represents a classic path traversal vulnerability that has been documented across numerous frameworks and applications.
The operational impact of CVE-2025-32950 extends beyond simple unauthorized file access, potentially enabling attackers to escalate privileges and gain deeper system access. An attacker could leverage this vulnerability to access database configuration files containing credentials, application secrets, or other sensitive information that could be used for further exploitation. The vulnerability also creates opportunities for attackers to potentially upload malicious files or execute arbitrary code, depending on the application's configuration and the permissions of the underlying file system. This type of vulnerability falls under the ATT&CK technique T1078.004, which describes valid accounts with elevated privileges, as the attacker can potentially gain access to system resources that would normally be restricted. The vulnerability's persistence across multiple framework versions indicates a systemic issue in the input validation implementation, suggesting that organizations running affected Jmix versions face prolonged exposure to this threat.
Organizations using affected Jmix versions should immediately implement the available patches, upgrading to versions 1.6.2 or 2.4.0 where the vulnerability has been addressed. The fix typically involves implementing proper input validation and sanitization of file reference parameters, ensuring that all user-supplied input is properly filtered to prevent path traversal sequences from being processed. Additionally, organizations should implement network segmentation and access controls to limit exposure of the affected endpoints, particularly the /files REST API endpoint. The recommended mitigation strategy includes implementing proper authentication and authorization checks, ensuring that file access operations are restricted to authorized users with appropriate privileges. Security teams should also conduct thorough code reviews to identify similar input validation issues in other parts of the application, as this vulnerability represents a broader pattern of insufficient input sanitization that could affect other components of the application stack. The workaround provided in Jmix documentation should be implemented immediately while planning for the full upgrade to ensure continued protection against this and related vulnerabilities.
