CVE-2026-20174
Full vulnerability record from the local CVENow database.
Description
A vulnerability in the Metadata update feature of Cisco Nexus Dashboard Insights could allow an authenticated, remote attacker to write arbitrary files to an affected system. This vulnerability is due to insufficient validation of the metadata update file. An attacker could exploit this vulnerability by crafting a metadata update file and manually uploading it to an affected device. A successful exploit could allow the attacker to write arbitrary files to the underlying operating system as the root user. To exploit this vulnerability, the attacker must have valid administrative credentials. Note: Manual uploading of metadata files is typical for Air-Gap environments but not for Cisco Intersight Cloud connected devices. However, the manual upload option exists for both deployments.

"value": "Una vulnerabilidad en la función de actualización de metadatos de Cisco Nexus Dashboard Insights podría permitir a un atacante remoto autenticado escribir archivos arbitrarios en un sistema afectado.\n\nEsta vulnerabilidad se debe a una validación insuficiente del archivo de actualización de metadatos. Un atacante podría explotar esta vulnerabilidad creando un archivo de actualización de metadatos y cargándolo manualmente en un dispositivo afectado. Un exploit exitoso podría permitir al atacante escribir archivos arbitrarios en el sistema operativo subyacente como usuario root. Para explotar esta vulnerabilidad, el atacante debe tener credenciales administrativas válidas.\nNota: La carga manual de archivos de metadatos es típica para entornos Air-Gap, pero no para dispositivos conectados a Cisco Intersight Cloud. Sin embargo, la opción de carga manual existe para ambas implementaciones."
