Vulnerability Details
The official description for CVE-2022-40022 states that Microchip Technology (Microsemi) SyncServer S650 contains a command injection vulnerability. This flaw is classified under CWE-77, which indicates improper neutralization of special elements used in a command (command injection).
The CVSS score for this vulnerability is 9.8, categorized as critical, indicating that successful exploitation could lead to severe impacts on confidentiality, integrity, and availability. The attack vector is network-based, with low complexity and no privileges or user interaction required.
Affected product includes the SyncServer S650 firmware, and organizations should ensure they are running the latest patched versions to mitigate the risks associated with this vulnerability.
Technical Analysis
The root cause of this vulnerability lies in the insufficient validation of user input, which allows attackers to inject arbitrary commands into the system. This command injection can be executed through network interfaces, making it particularly dangerous for devices that are exposed to the internet.
The attack complexity is low, meaning that it does not require advanced technical skills to exploit. Additionally, no privileges are required, and user interaction is not needed, which increases the attack surface significantly. The impact on confidentiality, integrity, and availability is rated high, indicating serious consequences for affected organizations.
Risk & Impact Analysis
The real-world risk associated with CVE-2022-40022 includes the potential for unauthorized access and control over critical network time synchronization services. Organizations relying on the SyncServer S650 for timekeeping may find their operations severely disrupted if exploited.
This vulnerability exemplifies the importance of securing network devices, particularly those exposed to the internet. The blast radius of an attack could extend beyond just the affected device, impacting the broader network and any services relying on accurate time synchronization.
With a critical CVSS score and significant EPSS percentile risk, organizations must evaluate their exposure and prioritize remediation efforts accordingly.
