Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

SI-10 Information Input Validation good match

prevent

Directly mitigates the command injection vulnerability by requiring validity checks and sanitization of JSON parameters to block shell metacharacters.

IA-8 Identification and Authentication (Non-organizational Users) good match

prevent

Prevents unauthenticated remote attackers from accessing the vulnerable /goform/formJsonAjaxReq endpoint by mandating identification and authentication for non-organizational users.

SI-2 Flaw Remediation good match

preventrecover

Ensures timely identification, reporting, and correction of the specific command injection flaw, including patching affected firmware versions.

MITRE ATT&CK Enterprise TechniquesAI

T1190 Exploit Public-Facing Application Initial Access

Adversaries may attempt to exploit a weakness in an Internet-facing host or system to initially access a network.

NVD Description

An issue was discovered on Tuoshi/Dionlink LT15D 4G Wi-Fi devices through M7628NNxlSPv2xUI_v1.0.1802.10.08_P4 and LT21B devices through M7628xUSAxUIv2_v1.0.1481.15.02_P0. A unauthenticated remote attacker with network access can exploit a command injection vulnerability. The /goform/formJsonAjaxReq endpoint fails to sanitize shell metacharacters sent via…

JSON parameters, thus allowing attackers to execute arbitrary OS commands with root privileges.

Deeper analysisAI

CVE-2024-53944 is a command injection vulnerability (CWE-94) affecting Tuoshi/Dionlink LT15D 4G Wi-Fi devices running firmware through M7628NNxlSPv2xUI_v1.0.1802.10.08_P4 and LT21B devices running firmware through M7628xUSAxUIv2_v1.0.1481.15.02_P0. The vulnerability resides in the /goform/formJsonAjaxReq endpoint, which fails to properly sanitize shell metacharacters in JSON parameters. This flaw enables attackers to inject and execute arbitrary operating system commands with root privileges. The issue carries a CVSS v3.1 base score of 9.8 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H), indicating critical severity due to its network accessibility and lack of prerequisites.

An unauthenticated remote attacker with network access to the device can exploit this vulnerability by sending crafted JSON requests to the affected endpoint. Successful exploitation grants root-level command execution on the underlying operating system, potentially allowing full device compromise, including data exfiltration, persistent access, modification of configurations, or disruption of services.
