CVE-2024-53944
Published: April 11, 2026
Official 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.
Technical Analysis
CVE-2024-53944 requires local access, meaning attackers must already have a foothold on the target system.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
CISA has added CVE-2024-53944 to the Known Exploited Vulnerabilities (KEV) catalog, confirming active exploitation in the wild. U.S. federal agencies are required to patch this within the mandated timeframe, and all organizations should treat remediation as urgent.
