CVE-2026-45685

Estado: AnalizadaAlta (7.5)—

OpenTelemetry eBPF Instrumentation provides eBPF instrumentation based on the OpenTelemetry standard. From version 0.1.0 to before version 0.9.0, malformed MongoDB wire messages can trigger uncaught panics in the MongoDB TCP parser, allowing a remote unauthenticated attacker to crash the telemetry agent and cause a denial of service. The parser operates on raw attacker-controlled network payloads before the input is fully validated, so a single crafted message can terminate telemetry collection for the affected process or node. This issue has been patched in version 0.9.0.

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 en aplicación de red expuesta (AV:N/PR:N/UI:N) explotable sin autenticación. Mensajes MongoDB malformados causan panic y terminación del servicio, DoS de telemetría.

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 0.1.0 hasta antes de la versión 0.9.0, los mensajes de cable de MongoDB malformados pueden desencadenar panics no capturados en el analizador TCP de MongoDB, permitiendo a un atacante remoto no autenticado bloquear el agente de telemetría y causar una denegación de servicio. El analizador opera sobre cargas útiles de red sin procesar controladas por el atacante antes de que la entrada sea completamente validada, por lo que un único mensaje manipulado puede terminar la recopilación de telemetría para el proceso o nodo afectado. Este problema ha sido parcheado en la versión 0.9.0."
