Overview
CVE-2025-64428 identifies a critical JNDI (Java Naming and Directory Interface) injection vulnerability affecting Dataease, an open-source data visualization and analysis tool. Versions prior to 2.10.17 are susceptible. While a blacklist intended to address this issue was introduced in version 2.10.14, the vulnerability remained exploitable through alternative JNDI schemes. A complete fix is available in Dataease version 2.10.17. It’s crucial to upgrade to this version as soon as possible.
Technical Details
The vulnerability stems from insufficient input validation when processing user-supplied data, particularly within JNDI lookup operations. Attackers can leverage this flaw to inject malicious JNDI URIs (Uniform Resource Identifiers) that, when processed by the Dataease server, can lead to remote code execution (RCE). The initial patch in version 2.10.14 attempted to block common JNDI protocols; however, researchers discovered that alternative schemes such as `iiop`, `corbaname`, and `iiopname` were not adequately filtered, allowing attackers to bypass the initial mitigation. The fixed version 2.10.17 addresses this bypass by implementing more comprehensive input sanitization and validation to prevent JNDI injection through any known or likely schemes.
CVSS Analysis
The CVE details indicate that the CVSS score and Severity are currently N/A. This will likely be updated as analysis progresses. Due to the potential for remote code execution, this vulnerability, when scored, is likely to receive a high or critical CVSS score.
Possible Impact
Successful exploitation of this vulnerability can have severe consequences, including:
- Remote Code Execution (RCE): An attacker can execute arbitrary code on the Dataease server, potentially gaining complete control of the system.
- Data Breach: Compromised servers can be used to access and steal sensitive data stored within the Dataease environment or connected databases.
- System Disruption: Attackers can disrupt normal operations by modifying or deleting data, or by causing the server to crash.
- Lateral Movement: A compromised Dataease server can be used as a pivot point to attack other systems within the network.
Mitigation and Patch Steps
The primary and recommended mitigation is to upgrade Dataease to version 2.10.17 or later. Follow these steps:
- Backup your Dataease instance: Before upgrading, create a full backup of your Dataease installation and database.
- Download the latest version: Download version 2.10.17 or later from the official Dataease GitHub repository.
- Follow the upgrade instructions: Refer to the official Dataease documentation for detailed instructions on upgrading your specific installation.
- Verify the installation: After the upgrade, verify that the new version is running correctly and that all features are functioning as expected.
Workaround (If immediate upgrade is not possible): As a temporary workaround, consider implementing network-level access control lists (ACLs) to restrict outbound connections from the Dataease server to untrusted hosts. This can limit the potential damage from a successful JNDI injection attack. However, this is not a substitute for upgrading to the patched version.
