CVE-2022-30262: Emerson Controlwave Micro Firmware

High severity, CVSS 7.8. EPSS: 0.2% chance of exploitation in the next 30 days.

The Emerson ControlWave 'Next Generation' RTUs through 2022-05-02 mishandle firmware integrity. They utilize the BSAP-IP protocol to transmit firmware updates. Firmware updates are supplied as CAB archive files containing a binary firmware image. In all cases, firmware images were found to have no authentication (in the form of firmware signing) and only relied on insecure checksums for regular integrity checks.

Affected products

• Emerson Controlwave Micro Firmware: up to and including 2022-05-02
• Emerson Controlwave Pac Firmware: up to and including 2022-05-02
