CVE-2017-8132 in FusionSphere OpenStack
Summary
by MITRE
The FusionSphere OpenStack with software V100R006C00 and V100R006C10 has a command injection vulnerability due to the insufficient input validation on four TCP listening ports. An unauthenticated attacker can exploit the vulnerabilities to gain root privileges by sending some messages with malicious commands.

The FusionSphere OpenStack platform version V100R006C00 and V100R006C10 contains a critical command injection vulnerability that stems from inadequate input validation mechanisms within its network communication protocols. This vulnerability exists across four specific TCP listening ports, creating multiple attack vectors that an unauthenticated malicious actor can exploit to achieve arbitrary code execution. The flaw represents a fundamental failure in the platform's input sanitization processes, where user-supplied data is not properly validated or filtered before being processed by the underlying system commands. The vulnerability classification aligns with CWE-77 and CWE-94, which respectively address command injection and code injection flaws that allow attackers to execute arbitrary commands on the target system. This weakness creates a direct pathway for privilege escalation attacks, as successful exploitation can result in complete system compromise with root-level privileges.
The technical exploitation of this vulnerability occurs through the manipulation of network traffic sent to the affected TCP ports, where maliciously crafted payloads containing shell commands are transmitted to the vulnerable system. These commands bypass normal input validation checks and are directly executed by the system's command processing mechanisms, effectively allowing attackers to perform any operation that the compromised service account has permissions to execute. The attack surface is particularly concerning because it requires no authentication, making it accessible to anyone who can reach the affected network ports, and the exploitation process can be automated to achieve rapid system compromise. The vulnerability's impact extends beyond simple command execution, as it enables attackers to establish persistent access, exfiltrate sensitive data, and potentially use the compromised system as a launching point for further attacks within the network infrastructure.
The operational impact of this vulnerability is severe and multifaceted, potentially affecting enterprise cloud infrastructure deployments that rely on FusionSphere OpenStack for their virtualization and container orchestration needs. Organizations using these specific software versions face significant risk of unauthorized access to their cloud environments, which could result in data breaches, service disruption, and compliance violations. The vulnerability's presence in widely deployed cloud infrastructure components makes it particularly dangerous, as successful exploitation can lead to complete compromise of the underlying virtualized environment. Attackers leveraging this vulnerability can perform reconnaissance activities, escalate privileges to root access, modify system configurations, and establish backdoors for continued access. The attack vector aligns with techniques described in the MITRE ATT&CK framework under the T1059.001 and T1068 categories, which cover command and scripting interpreters and exploit public-facing application respectively. Organizations may also face significant financial and reputational damage due to the potential for data loss and service interruption that such a vulnerability can cause.
Mitigation strategies for this vulnerability should focus on immediate remediation through official patches provided by Huawei, as well as network-level controls to restrict access to the affected TCP ports. Organizations should implement strict network segmentation policies to limit exposure of these services to untrusted networks and consider deploying network intrusion detection systems to monitor for suspicious traffic patterns. The implementation of proper input validation and sanitization mechanisms should be enforced throughout the platform, with regular security assessments to identify similar vulnerabilities in other components. Additionally, organizations should establish comprehensive monitoring and incident response procedures to quickly detect and respond to potential exploitation attempts, while maintaining up-to-date security configurations and access controls to minimize the attack surface. Regular vulnerability assessments and penetration testing should be conducted to ensure that similar weaknesses do not exist in other parts of the infrastructure, and security awareness training should be provided to system administrators to recognize potential exploitation attempts.
