CVE-2020-14094Public exploitNetwork attack vector

Remote code execution via connect sanitizer bypass

Published Jun 24, 2020 · Updated Aug 4, 2024

Command injection in Xiaomi Mi AIoT Router AX3600 ROM before 1.0.20 allows remote attackers to execute code via the web interface. The connect binary filters several shell metacharacters but accepts encoded line separators, so untrusted web input reaches command parsing. Network access to the management interface is sufficient; exploitation can crash the connection service through stack overflow or execute code.
