CVE-2020-37220
HighSummary
The Huawei HG630 V2 router contains an authentication bypass vulnerability that allows unauthenticated attackers to gain administrative access by retrieving the device serial number. Attackers can query the /api/system/deviceinfo endpoint without authentication to extract the SerialNumber field.
Risk Assessment
This vulnerability poses a serious risk to organizations as it allows attackers to gain full access to the router without authorization. This could lead to unauthorized changes to network configurations and data breaches.
Recommendation
It is recommended to update the router's firmware to the latest version that addresses this vulnerability. Additionally, access to the /api/system/deviceinfo endpoint should be restricted for unauthorized users.
