CVE-2026-35506Network attack vector

Authenticated command execution via ping_ip_addr injection

Published May 13, 2026 · Updated May 13, 2026

OS command injection in affected ELECOM wireless routers allows remote authenticated users to execute arbitrary commands via ping_ip_addr. The diagnostic ping request handler passes the ping_ip_addr value into an operating-system command without neutralizing command separators or other shell metacharacters. Access to the network management interface and a valid login are required; successful exploitation allows commands that can read or alter router data or interrupt operation.
