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).
