CVE-2026-30313

Estado: AnalizadaCrítica (9.8)—

DSAI-Cline's command auto-approval module contains a critical OS command injection vulnerability that renders its whitelist security mechanism completely ineffective. The system relies on string-based parsing to validate commands; while it intercepts dangerous operators such as ;, &&, ||, |, and command substitution patterns, it fails to account for raw newline characters embedded within the input.

Leer descripción completaMostrar menos

An attacker can construct a payload by embedding a literal newline between a whitelisted command and malicious code (e.g., git log malicious_command), forcing DSAI-Cline to misidentify it as a safe operation and automatically approve it. The underlying PowerShell interpreter treats the newline as a command separator, executing both commands sequentially, resulting in Remote Code Execution without any user interaction.

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 de inyección de comandos OS en módulo expuesto (AV:N, PR:N, UI:N). El atacante bypass el whitelist mediante newline embebido, logrando ejecución remota de código sin interacción.

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.

El sistema se basa en el análisis de cadenas para validar comandos; si bien intercepta operadores peligrosos como ;, &&, ||, | y patrones de sustitución de comandos, no tiene en cuenta los caracteres de nueva línea sin procesar incrustados en la entrada. Un atacante puede construir una carga útil incrustando una nueva línea literal entre un comando de lista blanca y código malicioso (por ejemplo, git log malicious_command), lo que obliga a DSAI-Cline a identificarlo erróneamente como una operación segura y aprobarlo automáticamente. El intérprete de PowerShell subyacente trata la nueva línea como un separador de comandos, ejecutando ambos comandos secuencialmente, lo que resulta en ejecución remota de código sin ninguna interacción del usuario."
