Authenticated command execution via unsanitized DDNS credentials
Published Aug 23, 2022 · Updated Sep 16, 2024
OS command injection in Linksys MR8300 Router firmware 1.0 allows remote authenticated users to execute commands through DDNS registration. The DDNS registration handler uses unsanitized username and password fields as URL-construction arguments, enabling redirection to an attacker-controlled server followed by script download and execution. Access to the authenticated router web interface from a connected device is required, and successful exploitation grants command execution on the router.
