CVE-2021-47728
Estado: AnalizadaCrítica (9.3)—
Selea Targa IP OCR-ANPR Camera contains an unauthenticated command injection vulnerability in utils.php that allows remote attackers to execute arbitrary shell commands. Attackers can exploit the 'addr' and 'port' parameters to inject commands and gain www-data user access through chained local file inclusion techniques.
CVSS
- Versión: 4.0
- Vector: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X
- Puntuación base: 9.3
Probabilidad de explotación (EPSS)
- Probabilidad de explotación en los próximos 30 días: 2.62%
- Percentil entre todas las CVEs puntuadas: 85
- Fecha de la puntuación: 5/10/2026
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.
- Explotación
T1190Exploit Public-Facing Applicationinitial access95 % - Impacto principal
T1059Command and Scripting Interpreterexecution90 % - Impacto secundario
T1068Exploitation for Privilege Escalationprivilege escalation75 %
Vector CVSS N/PR:N/UI:N indica acceso remoto sin autenticación. CWE-78 (command injection) en utils.php no autenticado justifica T1190. Impacto T1059 por ejecución de comandos shell arbitrarios; T1068 secundaria por potencial escalada hacia root/admin desde www-data.
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.
