CVE-2022-30262

CWE-345Published: August 17, 2022· Updated: Jun 17, 2026

7.8
CVSS v3.1

Official Description

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.

Technical Analysis

CVE-2022-30262 requires local access, meaning attackers must already have a foothold on the target system.

Exploitation requires low privileges, which limits the exposure to scenarios where an attacker has already gained initial access.

A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 7.8.
