CVE-2025-63675
cryptidy through 1.2.4 allows code execution via untrusted data because pickle.loads is used. This occurs in aes_decrypt_message in symmetric_encryption.py.
CVSS
- Versión: 3.1
- Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H
- Puntuación base: 8.8
Probabilidad de explotación (EPSS)
- Probabilidad de explotación en los próximos 30 días: 0.25%
- Percentil entre todas las CVEs puntuadas: 15
- Fecha de la puntuación: 6/10/2026
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
T1203Exploitation for Client Executionexecution90 % - Impacto principal
T1059Command and Scripting Interpreterexecution85 %
UI:R indica interacción del usuario (archivo/mensaje preparado); pickle.loads permite ejecución arbitraria de código Python. Vector remoto con interacción = T1203; impacto T1059 por RCE.
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.
