Executive Summary

This vulnerability is a command injection flaw in the alerts feature of CoolerControl's coolercontrold software versions prior to 4.0.0. Authenticated attackers can exploit this by injecting malicious bash commands into alert names, which are then executed with root privileges.

Impact Analysis

The impact of this vulnerability is severe because it allows an authenticated attacker to execute arbitrary code as the root user on the affected system. This can lead to full system compromise, including unauthorized access, data manipulation, disruption of services, and potential installation of persistent malware.

Mitigation Strategies

To mitigate this vulnerability, upgrade CoolerControl/coolercontrold to version 4.0.0 or later, as this version includes security improvements such as enabling TLS/SSL by default.

Compliance Impact

The vulnerability allows authenticated attackers to execute arbitrary code as root via command injection in alert names, which can lead to full system compromise.

Such a compromise can result in unauthorized access, modification, or destruction of sensitive data, potentially violating data protection requirements under standards like GDPR and HIPAA.

Therefore, this vulnerability poses a significant risk to compliance with these regulations by undermining the confidentiality, integrity, and availability of protected data.
