This vulnerability has a CVSS 3.0 base score of 7.8, rated HIGH. It requires local or adjacent network access to exploit. No authentication or special privileges are required for exploitation.
Technical Description
In Huawei HiRouter-CD20-10 with the versions before 1.9.6 and WS5200-10 with the versions before 1.9.6, there is a plug-in signature bypass vulnerability due to insufficient plug-in verification. An attacker may tamper with a legitimate plug-in to build a malicious plug-in and trick users into installing it. Successful exploit could allow the attacker to obtain the root permission of the device and take full control over the device.
Remediation
Check the references section for vendor advisories and patches from huawei. Update hirouter-cd20_firmware to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
