CVE-2020-29032Public exploitNetwork attack vector

Code execution via unchecked firmware archive

Published Mar 5, 2021 · Updated Sep 16, 2024

Code upload in Secomea GateManager before 9.4.621054022 allows remote attackers to execute code through tampered firmware. The firmware-update workflow accepts a repackaged gzip archive containing an attacker-modified service.sh script without verifying its integrity. A service operator must be tricked into uploading the archive; starting the service then runs the embedded code and can backdoor the server.
