Security Bulletin
This security bulletin contains information about 3 vulnerabilities.
1) Cleartext transmission of sensitive information
EUVDB-ID: #VU27382
Risk: Low
CVSSv3.1: 2.4 [CVSS:3.1/AV:A/AC:H/PR:N/UI:R/S:U/C:L/I:N/A:N/E:U/RL:U/RC:C]
CVE-ID: CVE-2020-7488
CWE-ID:
CWE-319 - Cleartext Transmission of Sensitive Information
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to gain access to sensitive information.
The vulnerability exists due to software uses insecure communication channel to transmit sensitive information. A remote attacker on the local network with ability to intercept network traffic can gain access to sensitive data transmitted between the software and the Modicon controllers.
MitigationCybersecurity Help is currently unaware of any official solution to address this vulnerability.
