CVE-2017-8147

CVE-2017-8147 is a MaxAge LSA vulnerability affecting numerous Huawei products, including various AC, AR, CloudEngine, E600, S-series, and Secospace USG6600 devices. The vulnerability stems from improper OSPF implementation, allowing an attacker to set the Link Status (LS) age to MaxAge (3600 seconds) by sending specially crafted LSA packets. This can lead to route table poisoning and a denial-of-service (DoS) attack. Rated with a CVSS v3.0 score of 7.5 (High), this vulnerability has a network attack vector and low attack complexity, requiring no user interaction. The primary impact is high availability, as an attacker can disrupt network services. There is no evidence of active exploitation, nor are there publicly available exploit modules in Metasploit, Nuclei, or ExploitDB. Community discussion and media coverage for this CVE are minimal, indicating a low level of public attention.
