Rockwell Automation ISaGRAF5 Runtime Use of Hard-coded Cryptographic Key
02 Description
Rockwell Automation ISaGRAF5 Runtime Use of Hard-coded Cryptographic Key
03 Exploitation and scoring
- 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.
- EPSS probability
- 1.16% probability of exploitation activity in the next 30 days.
- EPSS percentile
- Equal to or higher than the score of 66.9% of scored records. A rank, not a probability.
- NVD base score
- 6.5 (CVSS v3.x), scored by the NVD independently of the CNA.
- NVD CVSS vector
- CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N
- NVD analysis status
- Modified. NVD last modified this record on 2026-06-17.
- 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.

07 Remediation
Rockwell Automation recommends users update to ISaGRAF Runtime 5 Version 5.72.00. End users are encouraged to restrict or block access on TCP 1131 and TCP 1132 from outside the industrial control system. Confirm the least-privilege user principle is followed and user/service account access to Runtime's folder location is granted with a minimum amount of rights needed. Rockwell Automation recommends users of affected versions evaluate the mitigations provided and apply the appropriate mitigations to deployed products. Users are encouraged to combine this guidance with the general security guidelines for a comprehensive defense-in-depth strategy. To reduce risk, Rockwell Automation recommends users: Employ proper network segmentation and security controls. Minimize network exposure for all control system devices. Locate control systems behind firewalls. Isolate control systems from other networks when possible. Refer to the Converged Plantwide Ethernet (CPwE) Design and Implementation Guide for best practices deploying network segmentation and broader defense-in-depth strategies. Consider using proper network infrastructure controls, such as firewalls, UTM devices, VPN, or other security appliances. Ensure the least-privilege user principle is followed, and user/service account access to Runtime’s folder location is granted with a minimum amount of rights, as needed.
