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 ImpactpartialSuccessful exploitation gives limited 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
- 0.14% probability of exploitation activity in the next 30 days.
- EPSS percentile
- Ranks above 4.1% of scored records. A rank, not a probability.
- NVD base score
- 2.3 (CVSS v4.0), scored by the NVD independently of the CNA.

- 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.
Uninstall the Web Server
Who should apply this recommendation: All users not using the affected component
If your system does not require the use of the Web & Mobile features, you should make sure not to install them. If your system requires the use of the Web & Mobile features, they should be installed only on the Web Server.
See the product help related to the installation for more information.
Update IIS configuration – manually update HTTP headers
Who should apply this recommendation:
All users running affected components.
As a quick mitigation for the unnecessary and missing HTTP headers, you can disable default headers and add secure HTTP headers for all requests. Those options can be set via the web.config file located on the IIS by following those steps:
* Open the file
