Descriptions

A vulnerability in the web server of Cisco Integrated Management Controller (IMC) could allow an authenticated, remote attacker to set sensitive configuration values and gain elevated privileges. The vulnerability is due to improper handling of substring comparison operations that are performed by the affected software. An attacker could exploit this vulnerability by sending a crafted HTTP request to the affected software. A successful exploit could allow the attacker with read-only privileges to gain administrator privileges.

Una vulnerabilidad en el servidor web de Cisco Integrated Management Controller (IMC) podría permitir que un atacante remoto autenticado establezca valores de configuración confidenciales y obtenga privilegios elevados. La vulnerabilidad se debe al manejo inadecuado de las operaciones de comparación de subcadenas que realiza el software afectado. Un atacante podría aprovechar esta vulnerabilidad enviando una solicitud HTTP diseñada al software afectado. Una explotación exitosa podría permitir al atacante con privilegios de solo lectura obtener privilegios de administrador.
