CVE-2022-30274 : Exploit Details and Defense Strategies

Motorola ACE1000 RTU until 2022-05-02 is vulnerable due to unsafe ECB encryption usage. The device communicates with an XRT LAN-to-radio gateway via an embedded client, storing encrypted credentials using a hardcoded key. Additionally, it can route MDLC traffic over XCMP and XNL networks, with authentication protected by a hardcoded key.
