CVE-2022-42002 in SonicJS
Summary
by MITRE • 10/01/2022
SonicJS through 0.6.0 allows file overwrite. It has the following mutations that are used for updating files: fileCreate and fileUpdate. Both of these mutations can be called without any authentication to overwrite any files on a SonicJS application, leading to Arbitrary File Write and Delete.

The SonicJS vulnerability CVE-2022-42002 represents a critical authorization flaw that undermines the security posture of applications relying on this JavaScript framework for content management. This vulnerability exists within SonicJS versions up to 0.6.0 and stems from insufficient access controls on file manipulation operations. The framework exposes two primary mutations fileCreate and fileUpdate that are designed to handle file creation and modification tasks. These operations are fundamentally flawed because they lack proper authentication checks, allowing any remote attacker to invoke these functions without presenting valid credentials or authorization tokens. The absence of authentication requirements creates an exploitable condition where malicious actors can manipulate the file system through legitimate API endpoints that should be restricted to authorized users only.
The technical exploitation of this vulnerability occurs through the GraphQL API interface that SonicJS provides, where the fileCreate and fileUpdate mutations serve as attack vectors for arbitrary file operations. When these mutations are called without authentication, they operate with the privileges of the application process running the SonicJS server, typically running with elevated permissions on the host system. This privilege escalation enables attackers to overwrite existing files with malicious content, delete critical system files, or create new files in sensitive directories. The vulnerability is particularly dangerous because it allows for complete file system manipulation, potentially leading to system compromise, data destruction, or persistence mechanisms within the attacked environment. The flaw directly maps to CWE-285: Improper Authorization, which specifically addresses scenarios where systems fail to properly verify that operations are being performed by authorized entities.
The operational impact of CVE-2022-42002 extends beyond simple file manipulation to encompass broader system compromise and data integrity violations. Attackers can leverage this vulnerability to execute arbitrary code by overwriting configuration files, application binaries, or script files that are subsequently executed by the system. The vulnerability also enables data destruction scenarios where critical system files or user data can be deleted, leading to service disruption or complete system outages. Additionally, the ability to create new files allows attackers to establish persistence mechanisms such as backdoor scripts or malicious configuration files that maintain access to the compromised system. Organizations using SonicJS in production environments face significant risk of unauthorized access, data loss, and potential lateral movement within their network infrastructure. The vulnerability's impact aligns with ATT&CK technique T1078: Valid Accounts, as attackers can exploit the lack of authentication to gain unauthorized access to system resources, and T1486: Data Encrypted for Ransom, since the ability to overwrite files can be used to prepare for ransomware attacks.
Mitigation strategies for CVE-2022-42002 require immediate action to address the root cause of the authentication bypass. Organizations should upgrade to SonicJS versions that have implemented proper authentication checks for file operations, as version 0.6.1 and later releases contain the necessary security patches. The recommended approach involves implementing robust authentication mechanisms for all file manipulation operations, ensuring that only authorized users can invoke fileCreate and fileUpdate mutations. Security controls should include mandatory authentication tokens, role-based access controls, and proper input validation for file paths to prevent directory traversal attacks. Additionally, organizations should implement network segmentation to limit access to SonicJS endpoints, deploy web application firewalls to monitor and filter GraphQL requests, and establish proper logging and monitoring of file system operations. The implementation of these controls aligns with security frameworks such as NIST SP 800-53 controls for access control and system and information integrity, ensuring that organizations maintain compliance with industry standards while addressing the specific threat posed by this vulnerability. Regular security assessments and penetration testing should be conducted to verify that authentication mechanisms are properly implemented and functioning as intended.
