CVE-2022-47036Network attack vector

Root shell access via hardcoded password

Published Mar 18, 2024 · Updated Aug 27, 2024

Hardcoded credentials in Siklu MultiHaul TG devices allow remote authenticated users to obtain a root shell through debug login. The device image stores a shared root password as a weak md5crypt hash, enabling offline recovery and reuse by the debug login command. Administrative access to the device CLI is required; successful use grants a root shell with full control of the radio, and firmware alone does not identify the corrected hardware.
