CVE-2025-70957

Estado: AplazadaAlta (7.5)—

A Denial of Service (DoS) vulnerability was discovered in the TON Lite Server before v2024.09. The vulnerability arises from the handling of external arguments passed to locally executed "get methods." An attacker can inject a constructed Continuation object (an internal TVM type) that is normally restricted within the VM. When the TVM executes this malicious continuation, it consumes excessive CPU resources while accruing disproportionately low virtual gas costs. This "free" computation allows an attacker to monopolize the Lite Server's processing power, significantly reducing its throughput and causing a denial of service for legitimate users acting through the gateway.

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 remota sin autenticación (AV:N, PR:N, UI:N) en servicio expuesto (TON Lite Server). Impacto: agotamiento de recursos CPU mediante inyección de objeto Continuation malicioso, causando DoS de aplicación.

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.

Cuando la TVM ejecuta esta continuación maliciosa, consume recursos excesivos de CPU mientras acumula costos de gas virtual desproporcionadamente bajos.
