Technical 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).
Remediation
Check the references section for vendor advisories and patches from contec. Update cps-mg341-adsc1-111_firmware to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
