CVE-2020-14095Public exploitNetwork attack vector

Remote code execution via connect path injection

Published Jun 24, 2020 · Updated Aug 4, 2024

Injection in the Xiaomi Mi AIoT Router AX3600 connect service before 1.0.20 allows remote attackers to execute code via the web interface. A web-supplied scan path reaches a shell redirection; traversal can write through /tmp/miwifi-scan into procfs, while an oversized path overflows the stack for ROP. The published unauthenticated chain requires a separate login bypass before this endpoint can be reached.
