Cisco Aironet 1800, 2800, and 3800 Series Access Points Plug-and-Play Arbitrary Code Execution Vulnerability

Cisco Security Advisories - Thu, 09/21/2017 - 5:44pm
A vulnerability in the Plug-and-Play (PnP) subsystem of the Cisco Aironet 1800, 2800, and 3800 Series Access Points running a Lightweight Access Point (AP) or Mobility Express image could allow an unauthenticated, adjacent attacker to execute arbitrary code with root privileges.

The vulnerability is due to insufficient validation of PnP server responses. The PnP feature is only active while the device does not contain a configuration, such as a first time boot or after a factory reset has been issued. An attacker with the ability to respond to PnP configuration requests from the affected device can exploit the vulnerability by returning malicious PnP responses. If a Cisco Application Policy Infrastructure Controller - Enterprise Module (APIC-EM) is available on the network, the attacker would need to exploit the issue in the short window before a valid PnP response was received. If successful, the attacker could gain the ability to execute arbitrary code with root privileges on the underlying operating system of the device.

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

Cisco Mobility Express 1800 Access Point Series Authentication Bypass Vulnerability

Cisco Security Advisories - Thu, 09/21/2017 - 5:44pm
A vulnerability in the web-based GUI of Cisco Mobility Express 1800 Series Access Points could allow an unauthenticated, remote attacker to bypass authentication. The attacker could be granted full administrator privileges.

The vulnerability is due to improper implementation of authentication for accessing certain web pages using the GUI interface. An attacker could exploit this vulnerability by sending a crafted HTTP request to the web interface of the affected system. A successful exploit could allow the attacker to bypass authentication and perform unauthorized configuration changes or issue control commands to the affected device.

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