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

Description

The 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.

Mitigation

Cybersecurity Help is currently unaware of any official solution to address this vulnerability.

The attacker would have to send a specially crafted request to the affected application in order to exploit this vulnerability.

Is there known malware, which exploits this vulnerability?

No. We are not aware of malware exploiting this vulnerability.

2) Insufficient verification of data authenticity

EUVDB-ID: #VU27383

Risk: Low

CVSSv3.1: 6.5 [CVSS:3.1/AV:A/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:H/E:U/RL:U/RC:C]

CVE-ID: CVE-2020-7487

CWE-ID: CWE-345 - Insufficient Verification of Data Authenticity

Exploit availability: No

Description

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to insufficient verification of data authenticity issue. A remote attacker on the local network can execute arbitrary code on the Modicon controllers. 

Mitigation

Cybersecurity Help is currently unaware of any official solution to address this vulnerability.
