Emerson ControlWave up to 2022-05-02 BSAP-IP Protocol integrity check

CVSS Meta Temp Score
CVSS is a standardized scoring system to determine possibilities of attacks. The Temp Score considers temporal factors like disclosure, exploit and countermeasures. The unique Meta Score calculates the average score of different sources to provide a normalized scoring system.
Current Exploit Price (≈)
Our analysts are monitoring exploit markets and are in contact with vulnerability brokers. The range indicates the observed or calculated exploit price to be seen on exploit markets. A good indicator to understand the monetary effort required for and the popularity of an attack.
CTI Interest Score
Our Cyber Threat Intelligence team is monitoring different web sites, mailing lists, exploit markets and social media networks. The CTI Interest Score identifies the interest of attackers and the security community for this specific vulnerability in real-time. A high score indicates an elevated risk to be targeted for this vulnerability.

A vulnerability was found in Emerson ControlWave up to 2022-05-02. It has been classified as very critical. This affects an unknown code of the component BSAP-IP Protocol Handler. The manipulation with an unknown input leads to a integrity check vulnerability. CWE is classifying the issue as CWE-354. The product does not validate or incorrectly validates the integrity check values or "checksums" of a message. This may prevent it from detecting if the data has been modified or corrupted in transmission. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

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.

The weakness was disclosed 08/17/2022 as icsa-22-221-02. The advisory is shared at cisa.gov. This vulnerability is uniquely identified as CVE-2022-30262 since 05/04/2022. Neither technical details nor an exploit are publicly available. The price for an exploit might be around USD $0-$5k at the moment (estimation calculated on 08/17/2022).
