CVE-2022-25912 is a Remote Code Execution (RCE) vulnerability affecting the simple-git package, specifically versions prior to 3.15.0. Simple-git is a widely used Node.js library that provides a simple interface for running Git commands programmatically. The vulnerability arises when the ext transport protocol is enabled and exploited via the clone() method. This flaw is due to an incomplete fix of a previous vulnerability (CVE-2022-24066), which also involved command injection risks. The underlying weakness is classified under CWE-78 (Improper Neutralization of Special Elements used in an OS Command), indicating that user input or external data is not properly sanitized before being passed to system commands. An attacker who can control or influence the parameters passed to the clone() method with the ext transport protocol enabled could execute arbitrary commands on the host system with the privileges of the running application. Although no known exploits are currently reported in the wild, the vulnerability presents a significant risk because it allows remote attackers to execute arbitrary code without authentication or user interaction, assuming they can trigger the vulnerable code path. The lack of a patch link suggests that remediation involves upgrading to simple-git version 3.15.0 or later, where the issue has been addressed. Given the nature of simple-git as a development dependency, the vulnerability primarily impacts development environments, continuous integration/continuous deployment (CI/CD) pipelines, and any production systems that integrate simple-git for Git operations. Attackers exploiting this vulnerability could compromise the integrity and availability of affected systems, potentially leading to unauthorized access, data theft, or disruption of services.

For European organizations, the impact of CVE-2022-25912 can be significant, especially for those heavily reliant on Node.js development environments and automated DevOps pipelines that incorporate simple-git. Compromise of build servers or CI/CD infrastructure could lead to the injection of malicious code into software releases, supply chain attacks, or unauthorized access to internal repositories and systems. This could affect confidentiality by exposing sensitive source code and credentials, integrity by allowing tampering with codebases, and availability by disrupting development and deployment workflows. Sectors such as finance, telecommunications, and critical infrastructure, which often have complex software development and deployment processes, may face elevated risks. Additionally, organizations using containerized or cloud-based development environments that include simple-git are also vulnerable to remote exploitation. The medium severity rating reflects the need for attention but also the requirement for specific conditions (use of ext transport protocol and clone() method) to be met for exploitation. However, the potential for widespread impact in software supply chains and development environments makes this vulnerability a concern for European enterprises aiming to maintain secure software development lifecycles.

To mitigate CVE-2022-25912, European organizations should: 1) Immediately upgrade all instances of simple-git to version 3.15.0 or later, where the vulnerability has been fixed. 2) Audit all development, CI/CD, and production environments to identify where simple-git is used, especially focusing on automated scripts or services that invoke the clone() method with the ext transport protocol enabled. 3) Disable or avoid using the ext transport protocol in simple-git unless absolutely necessary, as this is the attack vector. 4) Implement strict input validation and sanitization for any parameters passed to Git commands within applications to prevent injection of malicious payloads. 5) Employ runtime application self-protection (RASP) or endpoint detection and response (EDR) tools to monitor for suspicious command execution patterns in development and build environments. 6) Enforce the principle of least privilege for services running simple-git to limit the impact of any potential compromise. 7) Regularly review and update dependency management policies to ensure timely patching of third-party libraries. 8) Conduct security awareness training for developers and DevOps teams about the risks of insecure use of Git libraries and the importance of secure coding practices.
