Mitigating Controls (NIST 800-53 r5)AI
Directly requires implementation of input validation at web interface endpoints to prevent exploitation of the improper input validation vulnerability (CWE-20).
Prohibits the use of discontinued and unsupported components like Eaton xComfort ECI, preventing exposure to unpatchable vulnerabilities.
Mandates identification and remediation of flaws like this command execution vulnerability through isolation or retirement of affected EOL devices.
Security SummaryAI
CVE-2025-59886 is an improper input validation vulnerability (CWE-20) affecting one of the endpoints in the web interface of Eaton xComfort ECI, a networked device. Rated at CVSS 3.1 score of 8.8 (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H), it stems from inadequate validation of inputs, enabling unauthorized command execution. The vulnerability was published on 2025-12-23.
An attacker with network access to the affected Eaton xComfort ECI device and low privileges (PR:L) can exploit this vulnerability without user interaction. Successful exploitation allows the execution of privileged user commands, potentially resulting in high-impact compromise of confidentiality, integrity, and availability.
Eaton's security bulletin (ETN-VA-2025-1022) advises that the xComfort ECI product has been discontinued to align with evolving cybersecurity standards. No patches, security updates, non-security updates, paid support, or technical content updates will be provided post-retirement.
Security practitioners should prioritize isolating or retiring affected xComfort ECI devices from networks, as no mitigations beyond discontinuation are available.
