I Found a Root Command Injection in Zyxel Enterprise APs. Here’s How I Emulated the Firmware CVE-2026-6837

I found this while reversing Zyxel’s WAX650S firmware and following the certificate export path. A password field used during PKCS#12 export could break into a shell command and execute as root.

The write-up covers the bug itself, how I traced it, and the full firmware-emulation setup I used to reproduce it without the physical AP.
