The FusionSphere OpenStack V100R006C00SPC102 (NFV) version contains a critical command injection vulnerability that represents a significant security risk for cloud infrastructure deployments. This vulnerability stems from inadequate input validation mechanisms within the system's command processing modules, specifically affecting the NFV (Network Functions Virtualization) implementation of the OpenStack platform. The flaw allows for remote code execution when exploited by an attacker with high privileges, potentially compromising the entire virtualized network function environment.
The technical root cause of this vulnerability aligns with CWE-77 and CWE-94, which classify it as a command injection flaw where user-supplied input is directly incorporated into system commands without proper sanitization or validation. The affected modules likely process administrative commands or configuration parameters that are passed to underlying operating system commands, creating an attack surface where malicious payloads can be executed with elevated privileges. This type of vulnerability typically occurs when developers assume that input will always conform to expected formats, failing to implement proper input validation and sanitization measures.
The operational impact of this vulnerability extends beyond simple code execution, as it provides attackers with the capability to escalate privileges and potentially gain full control over the virtualized infrastructure. In NFV environments, where network functions are deployed as virtual machines, this vulnerability could lead to complete compromise of network services, data exfiltration, or disruption of critical communications. The high privilege requirement suggests that the vulnerability may be exploitable through compromised administrative accounts or during legitimate administrative operations, making it particularly dangerous in environments where administrative access is frequently required.
Security professionals should consider this vulnerability in the context of the MITRE ATT&CK framework, specifically mapping it to techniques such as T1059.001 (Command and Scripting Interpreter: PowerShell) and T1068 (Exploitation for Privilege Escalation) where command injection serves as a foundational attack vector for deeper system compromise. Organizations should implement immediate mitigations including input validation controls, privilege separation measures, and network segmentation to limit the potential impact. The vulnerability also highlights the importance of proper security testing during development cycles, particularly for NFV implementations where the integration of virtualized network functions with cloud infrastructure creates additional attack surfaces that require comprehensive security assessment.
