CVE-2024-53944Known exploitationPublic exploitNetwork attack vector

Unauthenticated root command execution via JSON parameters

Published Feb 27, 2025 · Updated Mar 4, 2025

Command injection in Tuoshi/Dionlink LT15D and LT21B firmware allows remote attackers to execute root commands through a crafted HTTP request. The /goform/formJsonAjaxReq endpoint passes shell metacharacters from JSON parameters such as check_ip1 and check_ip2 without neutralization, so injected text is interpreted as operating-system commands. Network access to the device is sufficient and no authentication or user interaction is required, granting full root-level control of the router.
