Official Description

Inadequate encryption strength vulnerability in CONPROSYS IoT Gateway products allows a remote authenticated attacker with an administrative privilege to apply a specially crafted Firmware update file, alter the information, cause a denial-of-service (DoS) condition, and/or execute arbitrary code. The affected products and versions are as follows: M2M Gateway with the firmware Ver.3.7.10 and earlier (CPS-MG341-ADSC1-111, CPS-MG341-ADSC1-931, CPS-MG341G-ADSC1-111, CPS-MG341G-ADSC1-930, and CPS-MG341G5-ADSC1-931), M2M Controller Integrated Type with firmware Ver.3.7.6 and earlier versions (CPS-MC341-ADSC1-111, CPS-MC341-ADSC1-931, CPS-MC341-ADSC2-111, CPS-MC341G-ADSC1-110, CPS-MC341Q-ADSC1-111, CPS-MC341-DS1-111, CPS-MC341-DS11-111, CPS-MC341-DS2-911, and CPS-MC341-A1-111), and M2M Controller Configurable Type with firmware Ver.3.8.8 and earlier versions (CPS-MCS341-DS1-111, CPS-MCS341-DS1-131, CPS-MCS341G-DS1-130, CPS-MCS341G5-DS1-130, and CPS-MCS341Q-DS1-131).

Technical Analysis

CVE-2023-27389 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.

Exploitation requires high 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 7.2.
