CVE-2024-53944

Status: DeferredCritical (9.8)—

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.

CVSS

Version: 3.1
Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
Base score: 9.8

Exploitation probability (EPSS)

Probability of exploitation in the next 30 days: 40%
Percentile among all scored CVEs: 99
Score date: 10/6/2026

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
