The vulnerability CVE-2024-30269 represents a critical information disclosure flaw in DataEase, an open source data visualization and analysis platform that has been widely adopted for business intelligence and dashboard creation. This vulnerability affects versions prior to 2.5.0 and exposes sensitive database configuration information through an improperly secured API endpoint. The flaw manifests when an attacker accesses the specific path `/de2api/engine/getEngine;.js` through a web browser, which results in the platform returning its internal database connection details including credentials, hostnames, and potentially other sensitive configuration parameters. This represents a fundamental failure in the application's security architecture where sensitive operational data is exposed without proper authentication or authorization checks. The vulnerability directly maps to CWE-200, which defines information exposure as a weakness where information is exposed to unauthorized actors, and aligns with ATT&CK technique T1528, which covers "Credentials in Files" and represents how attackers can obtain sensitive information through improperly protected system resources. The exposure occurs at the application layer where the API endpoint fails to implement proper access controls, allowing any user with network access to retrieve critical database configuration details that could be leveraged for further attacks.
The technical implementation of this vulnerability stems from inadequate input validation and access control mechanisms within the DataEase platform's API routing system. When the `/de2api/engine/getEngine;.js` endpoint is accessed, the application does not perform proper authentication checks or authorization validation before returning database configuration information. This creates an information disclosure scenario where attackers can trivially obtain database connection strings, usernames, passwords, and potentially other sensitive configuration parameters that would normally be protected within a secure application environment. The vulnerability is particularly concerning because it allows unauthenticated access to database credentials that could enable attackers to directly connect to backend databases, potentially leading to data exfiltration, database manipulation, or further lateral movement within the network infrastructure. The flaw demonstrates poor secure coding practices where the application fails to implement proper security controls at the API level, making it vulnerable to reconnaissance and exploitation by threat actors with minimal technical expertise.
The operational impact of this vulnerability extends beyond simple information disclosure and creates significant risks for organizations using affected versions of DataEase. An attacker who discovers this vulnerability can immediately obtain database credentials and connection details, potentially enabling them to access sensitive business data stored in backend databases, modify database configurations, or perform unauthorized data operations. The exposure of database configuration information provides attackers with the necessary information to launch more sophisticated attacks including database injection, privilege escalation, or even complete system compromise if the database credentials have elevated privileges. Organizations may face regulatory compliance violations, data breaches, and reputational damage if this vulnerability is exploited successfully, as it provides attackers with direct access to sensitive organizational data through the exposed database connection information. The vulnerability also increases the attack surface for organizations by providing attackers with a clear path to access backend systems that would otherwise require additional exploitation techniques to achieve.
Organizations using DataEase versions prior to 2.5.0 should immediately implement the recommended mitigation strategy of upgrading to version 2.5.0 or later, as no effective workarounds are available for this vulnerability. The upgrade process should include comprehensive testing to ensure that the patched version maintains all necessary functionality while addressing the security flaw. Security teams should also implement network segmentation and access controls to limit access to the affected API endpoints until the upgrade is complete. Additional monitoring should be implemented to detect any unauthorized access attempts to the vulnerable endpoint, and organizations should conduct thorough security assessments to identify any potential compromise that may have occurred prior to the fix. The vulnerability highlights the importance of proper input validation, authentication, and authorization controls in web applications, and serves as a reminder that information disclosure vulnerabilities can have cascading effects on overall system security. Organizations should also review their application security practices to ensure that similar vulnerabilities are not present in other systems, particularly focusing on API security and the protection of sensitive configuration information within web applications.
