CVE-2026-102507

Estado: AplazadaMedia (6.8)—

Sliver C2 framework version 1.7.7 and earlier contains an unhandled panic vulnerability in the operator gRPC handler that allows an attacker controlling a compromised implant to crash the entire teamserver by returning a malformed or empty Download response. Attackers can send zero-length or 1-3 byte data payloads through a hostile implant session to trigger an out-of-bounds slice access in the vendored Binject library's BinaryMagic function, which propagates unrecovered through the operator gRPC interceptor chain and terminates the server process, affecting all connected operators.

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 AV:N/PR:L/UI:A indica explotación remota con interacción del usuario (T1203). La vulnerabilidad causa crash del servidor (DoS de aplicación T1499.004) mediante sesión comprometida.

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.
