This vulnerability allows command injection in systeminformation, a System and OS information library for node.js. The affected versions, specifically those prior to 5.31.0, are vulnerable due to unsanitized `locate` output that can be exploited through the `versions()` function. With a CVSS score of 8.8, categorized as high severity, this vulnerability poses significant risks to organizations utilizing the affected library.
Risk to organizations includes potential unauthorized command execution, which can lead to system compromise and data breaches. Given the attack vector is local, the exploitation requires the attacker to have low privileges. Therefore, it is critical for organizations to assess their risk exposure and prioritize remediation.
Organizations should prioritize patching immediately. The fix was implemented in version 5.31.0 of the systeminformation library. Failure to update could lead to severe consequences, including loss of data integrity and availability.
As of now, there are no public exploits confirmed for this vulnerability, nor is it listed in the Known Exploited Vulnerabilities (KEV) catalog, indicating that it is not actively being exploited in the wild. However, security teams should remain vigilant.
Vulnerability Details
The official description of this vulnerability states that systeminformation versions prior to 5.31.0 are susceptible to command injection via unsanitized `locate` output in `versions()`. The CVSS score of 8.8 indicates a high severity level, with high impacts on confidentiality, integrity, and availability.
The CWE classification for this vulnerability is CWE-78, which pertains to OS Command Injection. This classification emphasizes the nature of the vulnerability and the potential impact.
Technical Analysis
The root cause of this vulnerability lies in the failure to sanitize input from the `locate` command in the `versions()` function. Attackers may leverage this vulnerability locally, requiring minimal privileges to execute commands on the system. The attack complexity is rated as low, and no user interaction is required, making this a straightforward exploitation vector.
As for the impacts, the vulnerability can lead to high confidentiality, integrity, and availability impacts, which could severely affect systems that rely on the library for critical operations.
Risk & Impact Analysis
The real-world deployment risk associated with this vulnerability is significant due to the high CVSS score. Organizations using systeminformation in production environments may face severe consequences if they remain vulnerable, particularly if sensitive data is involved.
Given the nature of the attack vector, the blast radius could extend beyond the initial system, especially if the compromised system interacts with other critical infrastructure. Consequently, organizations should assess their operational environment and prioritize this vulnerability in their patch management strategies.
Based on the CVSS score and the lack of current exploitation, organizations should address this vulnerability in their priority patch cycle.
