CVE-2024-48440Public exploit

Unauthenticated command execution via AT-command input

Published Oct 24, 2024 · Updated Oct 25, 2024

Command injection in NR500-EA firmware RG500UEAABxCOMSLICv3.2.2543.12.18 allows remote attackers to run commands via at_command.asp. The unauthenticated web component accepts attacker-controlled AT-command input and passes it to the device command handler without neutralizing command syntax. Network adjacency is required; successful exploitation grants control of device commands, including a factory reset that interrupts service.
