Cisco Nexus Insights Authenticated Information Disclosure Vulnerability

A vulnerability in the web UI for Cisco Nexus Insights could allow an authenticated, remote attacker to view and download files related to the web application. The attacker requires valid device credentials. 

This vulnerability exists because proper role-based access control (RBAC) filters are not applied to file download actions. An attacker could exploit this vulnerability by logging in to the application and then navigating to the directory listing and download functions. A successful exploit could allow the attacker to download sensitive files that should be restricted, which could result in disclosure of sensitive information.

Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.

Cisco Prime Infrastructure and Cisco Evolved Programmable Network Manager Information Disclosure Vulnerability

A vulnerability in the CLI of Cisco Prime Infrastructure and Cisco Evolved Programmable Network (EPN) Manager could allow an authenticated, local attacker to access sensitive information stored on the underlying file system of an affected system.

This vulnerability exists because sensitive information is not sufficiently secured when it is stored. An attacker could exploit this vulnerability by gaining unauthorized access to sensitive information on an affected system. A successful exploit could allow the attacker to create forged authentication requests and gain unauthorized access to the affected system.

Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.

Cisco Enterprise NFV Infrastructure Software Authentication Bypass Vulnerability

A vulnerability in the TACACS+ authentication, authorization and accounting (AAA) feature of Cisco Enterprise NFV Infrastructure Software (NFVIS) could allow an unauthenticated, remote attacker to bypass authentication and log in to an affected device as an administrator.

This vulnerability is due to incomplete validation of user-supplied input that is passed to an authentication script. An attacker could exploit this vulnerability by injecting parameters into an authentication request. A successful exploit could allow the attacker to bypass authentication and log in as an administrator to the affected device.

Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.

Cisco NX-OS Software system login block-for Denial of Service Vulnerability

A vulnerability in the implementation of the system login block-for command for Cisco NX-OS Software could allow an unauthenticated, remote attacker to cause a login process to unexpectedly restart, causing a denial of service (DoS) condition.

This vulnerability is due to a logic error in the implementation of the system login block-for command when an attack is detected and acted upon. An attacker could exploit this vulnerability by performing a brute-force login attack on an affected device. A successful exploit could allow the attacker to cause a login process to reload, which could result in a delay during authentication to the affected device.

Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.

Cisco Application Policy Infrastructure Controller App Privilege Escalation Vulnerability

A vulnerability in an API endpoint of Cisco Application Policy Infrastructure Controller (APIC) and Cisco Cloud Application Policy Infrastructure Controller (Cloud APIC) could allow an authenticated, remote attacker with Administrator read-only credentials to elevate privileges on an affected system.

This vulnerability is due to an insufficient role-based access control (RBAC). An attacker with Administrator read-only credentials could exploit this vulnerability by sending a specific API request using an app with admin write credentials. A successful exploit could allow the attacker to elevate privileges to Administrator with write privileges on the affected device.

Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.
