Summary
CWE-20: Improper Input Validation vulnerability exists that could cause denial of service of engineering workstation when specific driver interface is invoked locally by an authenticated user with crafted input.
Remediation
For customers requiring the use of Uni-Telway driver, Schneider Electric recommends using following mitigations to reduce the risk of exploit:• McAfee Application and Change Control software for application control. Refer to the Cybersecurity Application Note available https://www.se.com/ww/en/download/document/EIO0000004778/ • Follow workstation, network and site-hardening guidelines in the Schneider Electric [Recommended Cybersecurity Best Practices](https://www.se.com/ww/en/download/document/7EN52-0390/) document. For customers not requiring the use of Uni-Telway driver, Schneider Electric recommends uninstalling the driver. Version 16.2 of EcoStruxureTM Control Expert, version 2025 of EcoStruxureTM Process Expert, version 2025 of EcoStruxureTM Process Expert for AVEVA System Platform, and version 3.63SP3 of OPC Factory Server do not include Uni-Telway driver by default anymore. This vulnerability is only affecting customers who have installed Uni-Telway driver.

01

What, why and how

CWE-20: Improper Input Validation vulnerability exists that could cause denial of service of engineering workstation when specific driver interface is invoked locally by an authenticated user with crafted input.

What

CWE-20: Improper Input Validation vulnerability exists that could cause denial of service of engineering workstation when specific driver interface is invoked locally by an authenticated user with crafted input.

Why

The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly.

How

An attacker operating through local access may attempt exploitation with low privileges. If successful, the issue may disrupt the affected service.

Why

How

An attacker operating through local access may attempt exploitation with low privileges. If successful, the issue may disrupt the affected service.

02

Exploit reality and attack path

CVSS severity, EPSS forecast probability, public exploit material and CISA-confirmed exploitation are separate signals.

Observed exploitation
?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.
No confirmed evidence

No CISA KEV match was present at the last successful refresh. This means no confirmation from that source, not proof of no exploitation.

Public PoC / exploit material
?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.
None recorded

No exploit-tagged reference or CISA SSVC proof-of-concept state is currently recorded. Research may still exist outside the structured feeds.
