CVE-2025-14187

Estado: AplazadaAlta (7.3)—

A weakness has been identified in UGREEN DH2100+ up to 5.3.0.251125. This affects the function handler_file_backup_create of the file /v1/file/backup/create of the component nas_svr. Executing a manipulation of the argument path can lead to buffer overflow. The attack can be executed remotely. The exploit has been made available to the public and could be used for attacks. It is recommended to upgrade the affected component.

🎯 Técnicas ATT&CK

Cómo se explota esta vulnerabilidad y qué consigue el atacante, en el lenguaje de MITRE ATT&CK.

ExplotaciónT1210 Exploitation of Remote Serviceslateral movement85 %
Impacto principalT1059 Command and Scripting Interpreterexecution80 %
Impacto secundarioT1068 Exploitation for Privilege Escalationprivilege escalation75 %

Buffer overflow en servicio remoto (NAS) con PR:H y ejecución de código. Acceso remoto sin UI:R indica T1210. El overflow en nas_svr permite ejecutar comandos (T1059) y potencialmente escalar a root (T1068).
