A malicious actor with access to the network and low privileges could exploit a series of authenticated SQL Injection vulnerabilities found in UniFi Talk Application to escalate privileges on the host device.

CVSS

Probabilidad de explotación (EPSS)

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).

🎯 Técnicas ATT&CK

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

SQL inyección autenticada (CWE-89) en servicio remoto con PR:L permite lectura de datos (T1005), manipulación (T1565.001) y escalada de privilegios (T1068) en host local; vector CVSS indica red + privs bajas.

Inferido por nuestro agente de análisis a partir de la descripción oficial, el vector CVSS y la CWE, y comprobado por un supervisor. Puede contener errores.
