The description for the former states that commands determined by the model to be safe will be automatically executed, whereas if the model judges a command to be potentially destructive, it still requires user approval. However, this design is highly susceptible to prompt injection attacks. An attacker can employ a generic template to wrap any malicious command and mislead the model into misclassifying it as a 'safe' command, thereby bypassing the user approval requirement and resulting in arbitrary command execution."}, {"lang": "es", "value": "En su diseño para la ejecución automática de comandos de terminal, SakaDev ofrece dos opciones: Ejecutar comandos seguros y ejecutar todos los comandos. La descripción de la primera opción establece que los comandos que el modelo determine como seguros se ejecutarán automáticamente, mientras que si el modelo juzga que un comando es potencialmente destructivo, aún requiere la aprobación del usuario. Sin embargo, este diseño es altamente susceptible a ataques de inyección de *prompts*. Un atacante puede emplear una plantilla genérica para envolver cualquier comando malicioso y engañar al modelo para que lo clasifique erróneamente como un comando 'seguro', eludiendo así el requisito de aprobación del usuario y resultando en la ejecución arbitraria de comandos."}], "metrics": {"cvssMetricV31": [{"source": "134c704f-9b21-4f2e-91b3-4a467353bcc0", "type": "Secondary", "cvssData": {"version": "3.1", "vectorString": "CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H", "baseScore": 9.8, "baseSeverity": "CRITICAL", "attackVector": "NETWORK", "attackComplexity": "LOW", "privilegesRequired": "NONE", "userInteraction": "NONE", "scope": "UNCHANGED", "confidentialityImpact": "HIGH", "integrityImpact": "HIGH", "availabilityImpact": "HIGH"}, "exploitabilityScore": 3.9, "impactScore": 5.9}]}, "weaknesses": [{"source": "134c704f-9b21-4f2e-91b3-4a467353bcc0", "type": "Secondary", "description": [{"lang": "en", "value": "CWE-94"}]}], "configurations": [{"nodes": [{"operator": "OR", "negate": false, "cpeMatch": [{"vulnerable": true, "criteria": "cpe:2.3:a:rahmanazhar:sakadev:*:*:*:*:*:visual_studio_code:*:*", "versionEndExcluding": "4.0.6", "matchCriteriaId": "61C12248-1044-43FF-9188-AFDF2B53EA4F"}]}]}], "references": [{"url": "https://github.com/Secsys-FDU/LLM-Tool-Calling-CVEs/issues/4", "source": "[email protected]", "tags": ["Mitigation", "Third Party Advisory"]}, {"url": "https://marketplace.visualstudio.com/items?itemName=rahmanazhar.saka-dev", "source": "[email protected]", "tags": ["Product"]}]}}
