CVE-2025-29226Network attack vector

Authenticated command execution via ping count parameter

Published Mar 21, 2025 · Updated Mar 25, 2025

Command injection in Linksys E5600 firmware 1.1.0.26 allows remote authenticated users to execute commands through the ping test interface. The runtime.pingTest function in \usr\share\lua\runtime.lua incorporates the pt["count"] value into a command without neutralizing command separators. Authentication to the network management interface is required, and injected commands execute on the router in the handler's security context.
