Description Preview
A denial of service vulnerability exists in multiple Huawei network security products including NGFW Module, NIP6300, NIP6600, NIP6800, Secospace USG6300, Secospace USG6500, Secospace USG6600, and SG9500. The vulnerability stems from improper handling of specially crafted packets. An attacker could exploit this vulnerability by sending many specific malicious packets to the affected devices, potentially causing service abnormalities or disruptions.
Overview
CVE-2020-9213 affects multiple Huawei network security products including firewalls and security gateways. The vulnerability is caused by improper packet handling mechanisms in the affected devices. When exploited, this vulnerability allows an attacker to send specially crafted packets that can trigger abnormal behavior in certain services running on the device. This could result in service disruption or a complete denial of service condition, impacting the availability of the network security infrastructure. The vulnerability affects specific versions of NGFW Module, NIP6300, NIP6600, NIP6800, Secospace USG6300, Secospace USG6500, Secospace USG6600, and SG9500 products.
Remediation
To address this vulnerability, organizations should implement the following measures:
- Update all affected Huawei devices to the latest firmware versions as provided in the Huawei security advisory (SA-20210210-02-DOS-EN).
- If immediate patching is not possible, implement network segmentation to restrict access to the management interfaces of the affected devices.
- Monitor network traffic for unusual patterns that might indicate exploitation attempts.
- Implement traffic rate limiting where possible to mitigate potential DoS attacks.
- Contact Huawei support for product-specific guidance if you're unable to apply the recommended updates.
- After patching, verify that the security updates have been successfully applied by checking the firmware version of your devices.
