Mate 9 smartphones with software MHA-AL00AC00B125 have a directory traversal vulnerability in Push module.
Mate 9 smartphones with software MHA-AL00AC00B125 have a directory traversal vulnerability in Push module. Since the system does not verify the file name during decompression, system directories are traversed. It could be exploited to cause the attacker to replace files and impact the service.

Remediation
Which version to upgrade to
Fix versions compiled from the vendor, package registries and Microsoft. Verify the vendor's note before upgrading.
No fix version is recorded for this entry. Check the references for vendor advisories.
Exploit status
No known public exploit
No public exploit has been observed yet. That doesn't mean you're safe, only that the bar is a little higher.
Research context
For pentesters and researchers: attack profile, score disagreement, timeline, patch commits, credits, variant and chain candidates, bug bounty scope. All derived from existing data; no exploit code.
Timeline
From publication to today: proof of concept, Metasploit module, CISA KEV and fix record. Dates are as reported by the sources.
No dated events beyond publication.

Root cause
A user-supplied file name is joined with the allowed directory, but the result is never checked to confirm it is still inside that directory.
