Huawei eCNS280_TD Resource Management Error Vulnerability

Huawei eCNS280_TD is the core network equipment of Huawei’s wireless broadband trunking system in China. Based on Network Functions Virtualization (NFV) and cloud-based architecture design, it provides network functions of traditional core networks, but also provides capacity configurations for each network element based on actual applications by virtualizing network element functions and sharing standardized hardware resources among multiple network elements to improve network expansion and reduction efficiency and enhance service uptime. Huawei eCNS280_TD has a resource management error vulnerability, which is caused by improper resource management of a function assignment and can be exploited by attackers to cause service abnormalities in affected devices.
