Privilege escalation via unsafe FTP chroot configuration
Published Jul 21, 2025 · Updated Jul 5, 2026
Improper access control in Linksys EA6350 firmware 2.1.2 allows local users to access system files through the FTP service. The dynamic vsftpd configuration enables chroot_local_user, creating the unsafe confinement state identified by the record. Exploitation requires low-privileged local access and user interaction; reported effects are file access and privilege escalation, not service interruption.
