Internal network reconnaissance via unauthorized administrative ping
Published Oct 17, 2025 · Updated Oct 17, 2025
Execution with unnecessary privileges in Moxa router firmware allows remote authenticated users to invoke the administrative ping function. The device API omits the role authorization needed to restrict that function to higher-privileged accounts and accepts calls from low-privileged sessions. A low-privileged account is required; affected releases end at 3.13, 3.14, 3.16, or 3.17 by series, and resulting probes expose reachable internal hosts while repeated requests consume minor device resources.

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.
