CVE-2026-47668 Scanner

DbGate is a data management and database administration tool widely used by database administrators, developers, and data analysts to manage and interact with various databases. It provides features to connect to different database servers, execute SQL queries, and perform data migrations. The tool supports multiple relational and non-relational databases, making it versatile and essential for data operations. DbGate is used in both development and production environments for efficient database management. It offers an intuitive interface to ease complex database tasks and improve productivity. Recently, it has been identified that older versions of DbGate may have potential vulnerabilities affecting system security.

The vulnerability in DbGate is a Remote Code Execution (RCE) that can be exploited via anonymous JWT tokens. This issue arises because the system issues anonymous JWT tokens through the /auth/login endpoint without proper authentication. This vulnerability allows an attacker to execute commands on the server by sending malicious requests to the /runners/start endpoint. The vulnerability stems from improper validation and execution of JavaScript payloads, which can lead to unauthorized access. This exposure can be particularly critical if not remediated promptly. The vulnerability jeopardizes the integrity and confidentiality of the affected system.

The vulnerability allows attackers to insert and execute arbitrary system commands, utilizing Node.js child_process function, through the /runners/start endpoint. Attackers can exploit this by sending specially crafted JavaScript payloads that are executed on the server, giving them access to execute any command with the same privileges as the DbGate process. The potential attack vector involves manipulating the authorization headers with Bearer tokens obtained from the /auth/login endpoint. The flaw lies in how DbGate processes these payloads, allowing for the unintended execution of commands. Such vulnerabilities often lead to severe security breaches if abused by malicious actors.

When exploited, this vulnerability enables an attacker to gain full control over the server, leading to a complete system compromise. Attackers can execute arbitrary commands, potentially leading to data exfiltration, installation of backdoors, or deployment of ransomware. They could also access and manipulate connected databases, extract sensitive data, and initiate lateral movements within the network. This unauthorized access can severely affect business operations, potentially leading to financial and reputational damage. It is crucial to address such vulnerabilities swiftly to prevent exploitation.
