| CVE-2026-81861 | Insufficiently Protected Credentials in Schneider Electric SCADAPack x70 RTUs CVE-2026-81861 is an insufficiently protected credentials flaw (CWE-522) affecting Schneider Electric SCADAPack x70 remote telemetry units (RTUs), in which authentication information is not adequately safeguarded. Because the flaw is network-reachable (AV:N) but requires some user interaction (UI:A) and for the vulnerable condition to be present (AT:P), an attacker would most plausibly induce an operator or legitimate user to take an action that exposes or transmits authentication data. A successful attack yields high confidentiality impact on the vulnerable system: exposure of authentication information that can then be reused to gain unauthorized access to RTU functionality, potentially allowing an adversary to read or manipulate remote telemetry and control operations. Organizations running SCADAPack x70 units in SCADA/ICS environments — typically utilities, oil and gas pipeline operators, and water/wastewater facilities — are the affected population. The issue carries a CVSS v4.0 base score of 5.9 (medium), is not in the CISA KEV catalog, and no public proof-of-concept or observed exploitation is known at this time. Do: Apply the Schneider Electric security notification and firmware/software updates for SCADAPack x70 as soon as the advisory specifies fixed builds, since exact patched versions are not listed in this data. Rotate all RTU and management-console credentials on the assumption they may have been exposed, and verify that x70 management/network interfaces are not reachable from untrusted networks (enforce OT segmentation, VPN, or allowlisting). Because user interaction is part of the attack chain, brief operators to treat unsolicited links, configuration files, or authentication prompts involving SCADAPack tooling with suspicion, and review authentication and access logs for anomalous RTU sessions. | 5.9 | — |

General Security Recommendations
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.
