CVE-2018-7933: Huawei Hirouter-CD20 Firmware

High severity, CVSS 7.8. EPSS: 1% chance of exploitation in the next 30 days.

Huawei home gateway products HiRouter-CD20 and WS5200 with the versions before HiRouter-CD20-10 1.9.6 and the versions before WS5200-10 1.9.6 have a path traversal vulnerability.

Successful exploit may result in arbitrary code execution or privilege escalation.
