Data disclosure and modification via insecure RSA
Published Sep 23, 2025 · Updated Sep 24, 2025
Broken cryptography in AutomationDirect CLICK PLUS firmware before 3.71 allows remote attackers to disclose or modify device data. The firmware's RSA implementation performs cryptographic operations insecurely, but the vendor has not disclosed the defective operation or affected protocol exchange. Exploitation requires no privileges but does require user interaction, with consequences bounded to data disclosure, data modification, and limited service interruption.

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.
