VAR-201512-0241
Vulnerability from variot - Updated: 2023-12-18 13:09Huawei USG5500, USG2100, USG2200, and USG5100 unified security gateways with software before V300R001C10SPC600, when "DHCP Snooping" is enabled and either "option82 insert" or "option82 rebuild" is enabled on an interface, allow remote attackers to cause a denial of service (reboot) via crafted DHCP packets. Multiple Huawei products are prone to a remote denial-of-service vulnerability. Successful exploits may allow an attackers to cause the affected device to restart, denying service to legitimate users. Huawei USG5500, USG2100, USG2200, and USG5100 are all unified security gateway products of Huawei in China. There are security vulnerabilities in many Huawei products. The following products and versions are affected: Huawei USG5500, USG2100, USG2200, and USG5100 using software versions earlier than V300R001C10SPC600
