Authenticated code execution via Binary Formatter deserialization
Published Aug 14, 2026 · Updated Aug 14, 2026
Untrusted-data deserialization in AVEVA Enterprise SCADA and Enterprise SCADA HMI allows remote authenticated users to execute code. The BinarySerializer accepts attacker-tampered Binary Formatter data and deserializes it instead of restricting input to JSON. Access requires DNA Authority - Operator privileges, and resulting code executes under the Enterprise SCADA DNA Apps security group.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
- Affected versionversion=0 <=2023_P1
- Affected versionversion=2024
- Affected versionversion=2024 R2
