CVE-2025-9230

Estado: AplazadaAlta (7.5)—

Issue summary: An application trying to decrypt CMS messages encrypted using password based encryption can trigger an out-of-bounds read and write.

Impact summary: This out-of-bounds read may trigger a crash which leads to Denial of Service for an application. The out-of-bounds write can cause a memory corruption which can have various consequences including a Denial of Service or Execution of attacker-supplied code.

Although the consequences of a successful exploit of this vulnerability could be severe, the probability that the attacker would be able to perform it is low. Besides, password based (PWRI) encryption support in CMS messages is very rarely used. For that reason the issue was assessed as Moderate severity according to our Security Policy.

The FIPS modules in 3.5, 3.4, 3.3, 3.2, 3.1 and 3.0 are not affected by this issue, as the CMS implementation is outside the OpenSSL FIPS module boundary.

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.

Vector CVSS AV:N/AC:L/PR:N → acceso remoto sin privilegios en T1190. OOB read/write puede causar DoS (T1499.004) o ejecución de código (T1059), aunque esta última tiene baja probabilidad según el texto.

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.

Besides, password based (PWRI) encryption support in CMS\nmessages is very rarely used. For that reason the issue was assessed as\nModerate severity according to our Security Policy.\n\nThe FIPS modules in 3.5, 3.4, 3.3, 3.2, 3.1 and 3.0 are not affected by this\nissue, as the CMS implementation is outside the OpenSSL FIPS module\nboundary."

La escritura fuera de límites puede causar una corrupción de memoria que puede tener varias consecuencias, incluyendo una Denegación de Servicio o la ejecución de código suministrado por el atacante.\n\nAunque las consecuencias de un exploit exitoso de esta vulnerabilidad podrían ser graves, la probabilidad de que el atacante pudiera realizarlo es baja. Además, el soporte de cifrado basado en contraseña (PWRI) en mensajes CMS se usa muy raramente. Por esa razón, el problema fue evaluado como de severidad Moderada según nuestra Política de Seguridad.\n\nLos módulos FIPS en 3.5, 3.4, 3.3, 3.2, 3.1 y 3.0 no se ven afectados por este problema, ya que la implementación de CMS está fuera del límite del módulo FIPS de OpenSSL."
