Authenticated runtime crash via inconsistent CmpAppBP request
Published Aug 3, 2023 · Updated Oct 11, 2024
Improper input validation in CODESYS products before 3.5.19.20 or 4.10.0.0 allows remote authenticated users to crash runtimes. CmpAppBP accepts inconsistent fields in crafted CODESYS protocol requests and uses them in an internal read from an invalid address. Successful product authentication is required; exploitation interrupts the affected runtime without reported data disclosure or modification.

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.
