03 Exploitation and scoring
SRC: CISA, FIRST, NVD, RED HAT- Exploitation
- Assessed, none found. CISA's assessment recorded neither public exploit code nor evidence of exploitation when it was made.
- SSVC decision
- ExploitationnoneCISA recorded no public exploit code and no evidence of exploitation.
- AutomatablenoAt least one step from reconnaissance to exploitation cannot be reliably automated.
- Technical ImpacttotalSuccessful exploitation gives total control of the vulnerable component.
CISA publishes the decision points, not a final SSVC decision. The decision also depends on mission and well-being impact, which is a property of your deployment rather than of the vulnerability.- EPSS probability
- 0.06% probability of exploitation activity in the next 30 days.
- EPSS percentile
- Ranks above 0.0% of scored records. A rank, not a probability.
- NVD base score
- 8.4 (CVSS v4.0), scored by the NVD independently of the CNA.
- NVD CVSS vector

- NVD analysis status
- Analyzed. NVD last modified this record on 2026-07-09.
- Red Hat severity
- No Red Hat rating. Red Hat rates the CVEs that affect its products.
Exploit-prediction scores from FIRST. Independent scoring and analysis status from the NVD. Vendor severity from Red Hat. Exploitation assessment and catalog membership from CISA.

Harden the configuration
Who should apply this recommendation: All users
To reduce the risk of exploitation, ARC Informatique strongly recommends implementing the following defensive measures:
* Minimize network exposure for all control system devices and/or systems, and ensure they are not accessible from insecure networks.
* Locate control system networks and remote devices behind firewalls and isolate them from business networks.
* When remote access is required, use secure methods, such as Virtual Private Networks (VPNs), recognizing VPNs may have vulnerabilities and should be updated to the most current version available. Also recognize VPN is only as secure as its connected devices.
Additional deployment guidance and recommended practices are available in the product documentation ( Hardening Guide https://www.pcvue.com/ProductHelp/PcVue/en/Content/Deployment/hardening-guide/overview.php ).
Update PcVue
Who should apply this recommendation: All users using the affected component
Apply the corrective update by installing PcVue Initial Release 17.0.0 or later
In a patched release, it will no longer be possible to load User directory from earlier versions. Existing projects designed with an earlier version require explicit migration using the ProjectUtility CLI tool. Instructions are provided in the product documentation ( Project Utility CLI reference https://www.pcvue.com/ProductHelp/PcVue/en/Content/Deployment/tools/project-utility-cli.php ).
