CVE-2024-55656

Estado: AplazadaAlta (8.8)—

RedisBloom adds a set of probabilistic data structures to Redis. There is an integer overflow vulnerability in RedisBloom, which is a module used in Redis. The integer overflow vulnerability allows an attacker (a redis client which knows the password) to allocate memory in the heap lesser than the required memory due to wraparound. Then read and write can be performed beyond this allocated memory, leading to info leak and OOB write. The integer overflow is in CMS.INITBYDIM command, which initialize a Count-Min Sketch to dimensions specified by user. It accepts two values (width and depth) and uses them to allocate memory in NewCMSketch(). This vulnerability is fixed in 2.2.19, 2.4.12, 2.6.14, and 2.8.2.

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.

AV:N/PR:L sin UI permite explotación remota de servicio (T1210). El overflow de enteros causa lectura OOB (T1005) y escritura OOB (T1565.001: manipulación de datos en memoria).

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.

Existe una vulnerabilidad de desbordamiento de enteros en RedisBloom, que es un módulo utilizado en Redis. La vulnerabilidad de desbordamiento de enteros permite a un atacante (un cliente de Redis que conoce la contraseña) asignar memoria en el montón menor que la memoria requerida debido al envoltorio. Luego, se pueden realizar operaciones de lectura y escritura más allá de esta memoria asignada, lo que genera una fuga de información y una escritura OOB. El desbordamiento de enteros se encuentra en el comando CMS.INITBYDIM, que inicializa un Count-Min Sketch con las dimensiones especificadas por el usuario. Acepta dos valores (ancho y profundidad) y los utiliza para asignar memoria en NewCMSketch(). Esta vulnerabilidad se corrigió en 2.2.19, 2.4.12, 2.6.14 y 2.8.2."
