CVE-2025-9317
AVEVA Edge Use of a Broken or Risky Cryptographic Algorithm
02 Description
AVEVA Edge Use of a Broken or Risky Cryptographic Algorithm
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
- 0.10% probability of exploitation activity in the next 30 days.
- EPSS percentile
- Equal to or higher than the score of 0.8% of scored records. A rank, not a probability.
- NVD base score
- 8.3 (CVSS v4.0), scored by the NVD independently of the CNA.
- NVD CVSS vector
- CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:N/VA:N/SC:H/SI:H/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X
- NVD analysis status
- Deferred. NVD last modified this record on 2026-10-18.
- 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
AVEVA recommends that organizations evaluate the impact of this vulnerability based on their operational environment, architecture, and product implementation. Users using the affected product versions should take the following actions to mitigate the risk of exploit: * Apply AVEVA Edge 2023 R2 P01 https://softwaresupportsp.aveva.com/en-US/downloads/products/details/38f52447-3013-4c4e-be6e-9b28b635bba9 * Security Update and migrate old project files. * For projects that cannot be migrated (e.g. backups or transient copies), evaluate the risk of potential password leakage from these files and implement stricter read access controls to protect these unsafe files. * Require AVEVA Edge users to change their passwords. * Important: Edge project migration from older versions to 2023 R2 P01 is one-way due to the change in password hashing algorithms. * For information on how to reach AVEVA support for your product, please refer to this link: AVEVA Customer Support https://www.aveva.com/en/support/support-contact/ .For more information, see AVEVA's Security Bulletin AVEVA-2025-006 https://www.aveva.com/content/dam/aveva/documents/support/cyber-security-updates/SecurityBulletin_AVEVA-2025-006.pdf or AVEVA's bulletins page https://www.aveva.com/en/support-and-success/cyber-security-updates/ .
