3.4 RESEARCHER

Sina Kheirkhah (@SinSinology) of Summoning Team (@SummoningTeam) working with Trend Micro Zero Day Initiative reported this vulnerability to CISA.

4. MITIGATIONS

Schneider Electric is establishing a remediation plan for all future versions of EcoStruxture Power Design – Ecodial that will include a fix for this vulnerability. Until then, customers should immediately apply the following mitigations to reduce the risk of exploit:

Compute hash of the project files and regularly check the consistency of this hash to verify the integrity before usage.
Store the hash information in a separate location from where the project file is stored.
When sharing or receiving project files with another user, the hash information should be provided over a separate, out of band channel.
When exchanging files over the network, use secure communication protocols.
Only open project files received from a trusted source.
Harden the workstation running the application.
Delete the accounts of people who no longer need access to the application and the computer running the application following the principle of least privilege.

To ensure you are informed of all updates, including details on affected products and remediation plans, subscribe to Schneider Electric’s security notification service.

Schneider Electric strongly recommends the following industry cybersecurity best practices.

Locate control and safety system networks and remote devices behind firewalls and isolate them from the business network.
Install physical controls so no unauthorized personnel can access your industrial control and safety systems, components, peripheral equipment, and networks.
Place all controllers in locked cabinets and never leave them in the “Program” mode.
Never connect programming software to any network other than the network intended for that device.
Scan all methods of mobile data exchange with the isolated network such as CDs, USB drives, etc., before use in the terminals or any node connected to these networks.
Never allow mobile devices that have connected to any other network besides the intended network to connect to the safety or control networks without proper sanitation.
Minimize network exposure for all control system devices and systems and ensure that they are not accessible from the Internet.
When remote access is required, use secure methods, such as Virtual Private Networks (VPNs). Recognize that VPNs may have vulnerabilities and should be updated to the most current version available. Also, understand that VPNs are only as secure as the connected devices.

CVE-2019-7260 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).

3.2.9 USE OF HARD-CODED CREDENTIALS CWE-798

Hard-coded credentials are present in multiple binaries bundled in the Nice Linear eMerge E3-Series versions 1.00-06 and prior firmware OS. These hard-coded credentials typically create a significant hole that could allow an attacker to bypass the authentication configured by the software administrator.

CVE-2019-7261 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).

3.2.10 USE OF HARD-CODED CREDENTIALS CWE-798

The Nice Linear eMerge E3-Series versions 1.00-06 and prior access control platform has SSH enabled with hardcoded credentials for the root account. This could allow an unauthenticated attacker to initiate a secure connection with highest privileges (root) and gain full system access.

CVE-2019-7265 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).

3.2.11 CROSS-SITE REQUEST FORGERY (CSRF) CWE-352

The application of Nice Linear eMerge E3-Series versions 1.00-06 and prior allows users to perform certain actions via HTTP requests without performing any validity checks to verify the requests. An attacker could exploit this to perform certain actions with administrative privileges if a logged-in user visits a malicious web site.

CVE-2019-7262 has been assigned to this vulnerability. A CVSS v3 base score of 8.8 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H).

3.2.12 OUT-OF-BOUNDS WRITE CWE-787

A stack-based buffer overflow exists, affecting several CGI binaries of Nice Linear eMerge E3-Series versions 1.00-06 and prior. The vulnerability is caused due to a boundary error in the processing of a user input, which an attacker could exploit to cause a buffer overflow. Successful exploitation could allow execution of arbitrary code on the affected device.

CVE-2019-7264 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).
