CVE-2026-20189
Full vulnerability record from the local CVENow database.
Description
A vulnerability in the log file download functionality of Cisco Prime Infrastructure could allow an authenticated, remote attacker to download arbitrary log files from the server. This vulnerability is due to insufficient authorization checks on the download service API. An attacker could exploit this vulnerability by submitting a crafted URL request to an affected device. A successful exploit could allow the attacker to download sensitive log files that they would otherwise not have authorization to access. To exploit this vulnerability, the attacker must have valid credentials to access the web-based management interface of the affected device.

Un atacante podría explotar esta vulnerabilidad al enviar una solicitud URL manipulada a un dispositivo afectado. Un exploit exitoso podría permitir al atacante descargar archivos de registro confidenciales a los que de otro modo no tendría autorización para acceder.\nPara explotar esta vulnerabilidad, el atacante debe tener credenciales válidas para acceder a la interfaz de gestión basada en web del dispositivo afectado."
