The vulnerability identified as CVE-2017-8191 affects FusionSphere OpenStack V100R006C00SPC102 within the NFV environment, representing a significant weakness in the cryptographic implementation that undermines data security during transmission. This issue stems from the use of insufficiently secure cryptographic algorithms that fail to provide adequate protection against cryptanalytic attacks, creating a pathway for unauthorized parties to potentially decrypt sensitive information.
The technical flaw manifests in the system's inability to properly implement strong encryption standards during data transmission processes, making it susceptible to various forms of cryptographic attacks including brute force and statistical analysis. The weakness specifically impacts the cipher text protection mechanisms, allowing attackers to exploit predictable patterns or weak key generation processes that compromise the confidentiality of transmitted data. This vulnerability directly relates to CWE-327, which addresses the use of weak cryptographic algorithms, and represents a critical failure in the security architecture that governs data protection in network functions virtualization environments.
The operational impact of this vulnerability extends beyond simple data exposure, as it creates opportunities for attackers to intercept and manipulate sensitive information flowing through the NFV infrastructure. Organizations utilizing this version of FusionSphere OpenStack face potential risks including unauthorized access to operational data, service disruption through man-in-the-middle attacks, and compromise of the entire virtualized network function ecosystem. The vulnerability particularly affects environments where secure communication between virtual network functions and management systems is critical for maintaining service integrity and regulatory compliance.
Mitigation strategies should prioritize immediate implementation of stronger cryptographic protocols including the adoption of AES-256 or higher encryption standards, proper key management practices, and regular security assessments of the cryptographic implementations. Organizations must also consider upgrading to supported versions of FusionSphere OpenStack that address this vulnerability and implement network segmentation to limit the potential impact of successful attacks. The remediation process should align with NIST SP 800-57 guidelines for cryptographic key management and incorporate principles from the MITRE ATT&CK framework to address potential exploitation techniques targeting weak cryptographic implementations in virtualized environments.
