Root code execution via unchecked acsd copy
Published Oct 4, 2023 · Updated Sep 20, 2024
Stack-based buffer overflow in Extreme Networks IQ Engine before 10.6r2 allows network-adjacent attackers to execute code as root. The default TCP port 5916 ah_acsd service copies user-supplied data into a fixed-length stack buffer without first validating its length. Exploitation requires network adjacency but no authentication, and successful exploitation grants root-level control of the access point.

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.
