Successful exploitation of these vulnerabilities could allow an attacker to completely compromise the products.
The following versions of myPRO, an HMI/SCADA system, are affected:
An unauthenticated remote attacker can access the application without any form of authentication or authorization.
CVE-2021-43985 has been assigned to this vulnerability. A CVSS v3 base score of 9.1 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N).
The affected product stores passwords using MD5, which may allow an attacker to crack the previously retrieved password hashes.
CVE-2021-43989 has been assigned to this vulnerability. A CVSS v3 base score of 7.5 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N).
An additional, nondocumented administrative account exists in the affected product that is not exposed through the web interface, which cannot be deleted or changed through the regular web interface.
CVE-2021-43987 has been assigned to this vulnerability. A CVSS v3 base score of 9.8 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H).
The affected product has a vulnerable debug interface which includes a ping utility, which may allow an attacker to inject arbitrary operating system commands.
CVE-2021-44453 has been assigned to this vulnerability. A CVSS v3 base score of 10.0 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H).
The affected product has a feature where the API password can be specified, which may allow an attacker to inject arbitrary operating system commands through a specific parameter.
CVE-2021-22657 has been assigned to this vulnerability. A CVSS v3 base score of 10.0 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H).
The affected product has a feature where the password can be specified, which may allow an attacker to inject arbitrary operating system commands through a specific parameter.
CVE-2021-23198 has been assigned to this vulnerability. A CVSS v3 base score of 10.0 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H).
The affected product has a feature to send emails, which may allow an attacker to inject arbitrary operating system commands through a specific parameter.
CVE-2021-43981 has been assigned to this vulnerability. A CVSS v3 base score of 10.0 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H).
The affected product has a feature where the firmware can be updated, which may allow an attacker to inject arbitrary operating system commands through a specific parameter.
CVE-2021-43984 has been assigned to this vulnerability. A CVSS v3 base score of 10.0 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H).
Michael Heinzl reported these vulnerabilities to CISA.
