Due to the lack of validation while these home gateway products install APK plugins, an attacker tricks a user into installing a malicious APK plugin, and plugin can overwrite arbitrary file of devices. Successful exploit may result in arbitrary code execution or privilege escalation.","published":"2018-05-10T14:29:01.000Z","lastModified":"2026-06-17T02:03:58.000Z","status":"Modified","sourceIdentifier":"psirt@huawei.com","cvss":{"version":"3.0","score":7.8,"severity":"HIGH","vector":"CVSS:3.0/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H"},"cwe":["CWE-22"],"affected":["huawei/hirouter-cd20 firmware","huawei/ws5200 firmware"],"epss":{"score":0.01022,"percentile":0.63261,"date":"2026-10-27","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"high","text":"High impact if exploited, but EPSS currently rates exploitation as unlikely (1.02%).
