CVE-2025-40905
WWW::OAuth 1.000 and earlier for Perl uses the rand() function as the default source of entropy, which is not cryptographically secure, for cryptographic functions.
CVSS
- Versión: 3.1
- Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L
- Puntuación base: 7.3
Probabilidad de explotación (EPSS)
- Probabilidad de explotación en los próximos 30 días: 0.27%
- Percentil entre todas las CVEs puntuadas: 17
- 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

- Explotación
T1190Exploit Public-Facing Applicationinitial access85 % - Impacto principal
T1212Exploitation for Credential Accesscredential access75 % - Impacto secundario
T1550.001Application Access Tokenlateral movement70 %
Vector AV:N/PR:N permite T1190. CWE-338 (rand() débil) compromete generación de tokens OAuth, permitiendo falsificación de credenciales (T1212) y acceso no autorizado con credenciales robadas (T1550.001).
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.
