A vulnerability was found in Huawei HiRouter-CD20 and WS5200 (Router Operating System) (the affected version unknown). It has been classified as critical. Affected is an unknown part. The manipulation with an unknown input leads to a path traversal vulnerability. CWE is classifying the issue as CWE-22. The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

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. 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.

The bug was discovered 05/02/2018. The weakness was disclosed 05/10/2018 (Website). The advisory is available at huawei.com. This vulnerability is traded as CVE-2018-7933 since 03/09/2018. It is possible to launch the attack remotely. The exploitation doesn't require any form of authentication. Successful exploitation requires user interaction by the victim. The technical details are unknown and an exploit is not available. This vulnerability is assigned to T1006 by the MITRE ATT&CK project.

The vulnerability was handled as a non-public zero-day exploit for at least 8 days. During that time the estimated underground price was around $5k-$25k.

Upgrading eliminates this vulnerability.

The entry VDB-118160 is pretty similar.
