Technical Details
#### CVE-2026-1762: DLL Hijacking
This vulnerability arises from an uncontrolled search path element in the Enervista UR Setup installer. When the installer is executed in a directory containing malicious DLL files, attackers can exploit this flaw to execute arbitrary code with administrative privileges. The vulnerability is classified under CWE-427 (Uncontrolled Search Path Element) and carries a CVSS score of 7.8, indicating a high risk of exploitation.
#### CVE-2026-1763: Path Traversal
The second vulnerability involves a path traversal flaw in the firmware update process. Attackers can craft malicious firmware update files to write to arbitrary locations on the filesystem, potentially corrupting critical files or injecting malicious payloads. This flaw is tracked as CWE-35 (Path Traversal: '.../...//') and has a CVSS score of 3.3, reflecting a lower but still significant risk.
---
Impact Assessment
The vulnerabilities pose a severe risk to organizations in critical infrastructure sectors, including:
- Energy: Power generation and distribution systems.
- Water and Wastewater: Treatment and distribution facilities.
- Critical Manufacturing: Industrial production environments.
Successful exploitation of CVE-2026-1762 could grant attackers full control over affected systems, leading to data breaches, operational disruptions, or even physical damage. While CVE-2026-1763 has a lower severity, it could still enable attackers to manipulate system files, compromising integrity and availability.
---
Attack Vector
- CVE-2026-1762: Requires local access to a system with the Enervista UR Setup installer running in an untrusted directory.
- CVE-2026-1763: Exploitable by tricking a user into opening a malicious firmware update file.
Neither vulnerability is exploitable remotely, reducing the immediate risk of large-scale attacks. However, targeted attacks remain a significant concern.

Mitigation Steps
GE Vernova has released a patched version of Enervista UR Setup (version 8.70 or later) to address these vulnerabilities. Organizations are urged to:
1. Upgrade Immediately: Download and install the latest version from [GE Vernova’s official resources](https://www.gevernova.com/grid-solutions/resources?prod=urfamily&type=7).
2. Isolate Critical Systems: Ensure control system networks are not accessible from the internet or business networks.
3. Use Secure Remote Access: Employ Virtual Private Networks (VPNs) for remote access, keeping them updated to the latest versions.
4. Monitor for Suspicious Activity: Implement intrusion detection systems to identify potential exploitation attempts.
CISA recommends adopting a defense-in-depth strategy to enhance the security of ICS environments. Detailed guidance is available in their [ICS Cybersecurity Best Practices](https://www.cisa.gov/ics).
