CVE-2025-32023

Estado: ModificadaAlta (7.8)—

Redis is an open source, in-memory database that persists on disk. From 2.8 to before 8.0.3, 7.4.5, 7.2.10, and 6.2.19, an authenticated user may use a specially crafted string to trigger a stack/heap out of bounds write on hyperloglog operations, potentially leading to remote code execution. The bug likely affects all Redis versions with hyperloglog operations implemented. This vulnerability is fixed in 8.0.3, 7.4.5, 7.2.10, and 6.2.19. An additional workaround to mitigate the problem without patching the redis-server executable is to prevent users from executing hyperloglog operations. This can be done using ACL to restrict HLL commands.

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.

Vulnerabilidad local (AV:L) con privilegios autenticados (PR:L) que permite escritura fuera de límites en operaciones HyperLogLog, escalando a ejecución remota de código en Redis.

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.

Desde la versión 2.8 hasta versiones anteriores a la 8.0.3, 7.4.5, 7.2.10 y 6.2.19, un usuario autenticado podía usar una cadena especialmente manipulada para activar una escritura fuera de los límites de pila/montón en operaciones de hyperloglog, lo que podría provocar la ejecución remota de código. Es probable que el error afecte a todas las versiones de Redis con operaciones de hyperloglog implementadas. Esta vulnerabilidad se ha corregido en las versiones 8.0.3, 7.4.5, 7.2.10 y 6.2.19. Otra solución alternativa para mitigar el problema sin parchear el ejecutable redis-server es impedir que los usuarios ejecuten operaciones de hyperloglog. Esto se puede lograr mediante ACL para restringir los comandos HLL."
