CVE-2026-40006

Estado: AplazadaAlta (7.5)—

Memory Allocation with Excessive Size Value, Allocation of Resources Without Limits or Throttling, Missing Authentication for Critical Function vulnerability in Apache IoTDB. When pipe_air_gap_receiver_enabled=true, the IoTDB AirGap pipe receiver accepts raw TCP connections on port 9780 with no authentication. The readLength method reads an attacker-controlled 32-bit integer from the socket and readData passes it directly to new byte[length] with no upper-bound check. An unauthenticated attacker can cause the JVM to attempt an allocation of up to 2,147,483,647 bytes per connection, exhausting heap memory and crashing or severely degrading the DataNode process.

This issue affects Apache IoTDB: from 1.0.0 before 2.0.10.

Users are recommended to upgrade to version 2.0.10, which fixes the issue.

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.

Acceso sin autenticación en puerto expuesto (AV:N, PR:N) permite DoS por agotamiento de memoria mediante asignación no limitada. La predicción de T1078 es débil: no hay prueba de acceso a cuentas.

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.
