This directory is typically world-readable, allowing any local user or application to access the token. If the token is leaked (e.g., via malware infection or other local exploit), and remote access is enabled, it can be used to establish unauthorized remote connections to the sequencer. Remote access must be enabled for remote exploitation to succeed. This may occur either because the user has enabled remote access for legitimate operational reasons or because malware with elevated privileges (e.g., sudo access) enables it without user consent. This vulnerability can be chained with remote access capabilities to generate a developer token from a remote device. Developer tokens can be created with arbitrary expiration dates, enabling persistent access to the sequencer and bypassing standard authentication mechanisms."}, {"lang": "es", "value": "El software MinKNOW de Oxford Nanopore Technologies en la versi\u00f3n 24.11 o anteriores almacena tokens de autenticaci\u00f3n en un archivo ubicado en el directorio temporal del sistema (/tmp) en la m\u00e1quina anfitriona. Este directorio es t\u00edpicamente legible por todos, permitiendo que cualquier usuario o aplicaci\u00f3n local acceda al token. Si el token se filtra (por ejemplo, a trav\u00e9s de una infecci\u00f3n de malware u otro exploit local), y el acceso remoto est\u00e1 habilitado, puede usarse para establecer conexiones remotas no autorizadas al secuenciador. El acceso remoto debe estar habilitado para que la explotaci\u00f3n remota tenga \u00e9xito. Esto puede ocurrir bien porque el usuario ha habilitado el acceso remoto por razones operativas leg\u00edtimas o porque un malware con privilegios elevados (por ejemplo, acceso sudo) lo habilita sin el consentimiento del usuario. Esta vulnerabilidad puede encadenarse con las capacidades de acceso remoto para generar un token de desarrollador desde un dispositivo remoto. Los tokens de desarrollador pueden crearse con fechas de caducidad arbitrarias, permitiendo el acceso persistente al secuenciador y eludiendo los mecanismos de autenticaci\u00f3n est\u00e1ndar."}], "lastModified": "2026-10-08T11:10:00.250", "sourceIdentifier": "ics-cert@hq.dhs.gov"}
