Schneider Electric is aware of multiple vulnerabilities in its Easergy T200 products.
The Easergy T200 RTU Product Line (T200I, T200E, T200P) is a modular platform for medium
voltage and low voltage public distribution network management. Note, this product has been
obsoleted since December 31st, 2021, and is no longer available for purchase.
Failure to apply the remediations provided below may allow a brute force attack, which could
result in unauthorized data access, and/or compromise of the device

Affected Products and Models

Vulnerability Details
CVE ID: CVE-2024-2051
CVSS v3.1 Base Score 9.8 | Critical | CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
CWE-307: Improper Restriction of Excessive Authentication Attempts vulnerability exists that
could cause account takeover and unauthorized access to the system when an attacker
conducts brute-force attacks against the login form.

CVE ID: CVE-2024-2050
CVSS v3.1 Base Score 8.2 | High| CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:L/A:N
CWE-79: Improper Neutralization of Input During Web Page Generation (‘Cross-site Scripting’)
vulnerability exists when an attacker injects then executes arbitrary malicious JavaScript code
within the context of the product.
CVE ID: CVE-2024-2052
CVSS v3.1 Base Score 7.5 | High | [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N]
CWE-552: Files or Directories Accessible to External Parties vulnerability exists that could allow
unauthenticated files and logs exfiltration and download of files when an attacker modifies the
URL to download to a different location.
Note regarding vulnerability details: The severity of vulnerabilities was calculated using the
CVSS Base metrics in version 3.1 (CVSS v3.1) without incorporating the Temporal and
Environmental metrics. Schneider Electric recommends that customers score the CVSS
Environmental metrics, which are specific to end-user organizations, and consider factors such
as the presence of mitigations in that environment. Environmental metrics may refine the
relative severity posed by the vulnerabilities described in this document within a customer’s


After upgrade, the device will reboot automatically.

General Security Recommendations
We strongly recommend the following industry cybersecurity best practices.

Schneider Electric Security Notification

  • 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.

    Practices document.
