CVE-2020-8644
PlaySMS versiones anteriores a 1.4.3, no sanea las entradas de una cadena maliciosa.
CVSS
- Versión: 3.1
- Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
- Puntuación base: 9.8
Probabilidad de explotación (EPSS)
- Probabilidad de explotación en los próximos 30 días: 87%
- Percentil entre todas las CVEs puntuadas: 100
- Fecha de la puntuación: 7/10/2026
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).
CISA KEV — explotada activamente
- Añadida al catálogo: 3/11/2021
- Plazo de remediación: 3/5/2022
- Uso conocido en ransomware: Unknown
💥 Exploits públicos
Hay código de explotación o plantillas de detección públicos. No es lo mismo que explotación activa confirmada (KEV), pero aumenta el riesgo: parchee con prioridad.
- Módulo de Metasploit (exploit fiable y al alcance de cualquiera) · PlaySMS index.php Unauthenticated Template Injection Code Execution
- Publicado en Exploit-DB · PlaySMS - index.php Unauthenticated Template Injection Code Execution (Metasploit) (16/4/2020)
- Plantilla de Nuclei (detección automática y masiva) · playSMS <1.4.3 - Remote Code Execution
- Prueba de concepto en GitHub (no verificada) · Lista de pruebas de concepto en GitHub
⚠️ Las pruebas de concepto de GitHub no están verificadas: algunas son falsas o contienen malware. No las ejecute nunca fuera de un laboratorio aislado.
🎯 Técnicas ATT&CK
Cómo se explota esta vulnerabilidad y qué consigue el atacante, en el lenguaje de MITRE ATT&CK.
