Multiple vulnerabilities in the Cisco AnyConnect VPN server of Cisco Meraki MX and Cisco Meraki Z Series Teleworker Gateway devices could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition to the AnyConnect VPN service on an affected device.For more information about these vulnerabilities, see the Details section of this advisory.Cisco Meraki has released software updates that address these vulnerabilities. There are no workarounds that address these vulnerabilities.This advisory is available at the following link:https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-meraki-mx-vpn-dos-QTRHzG2

Multiple Cisco products are affected by a vulnerability in the Snort detection engine that could allow an unauthenticated, remote attacker to bypass a configured File Policy for HTTP. The vulnerability is due to incorrect detection of modified HTTP packets used in chunked responses. An attacker could exploit this vulnerability by sending crafted HTTP packets through an affected device. A successful exploit could allow the attacker to bypass a configured File Policy for HTTP packets and deliver a malicious payload.

A vulnerability in the local status page functionality of the Cisco Meraki MR, MS, MX, Z1, and Z3 product lines could allow an authenticated, remote attacker to modify device configuration files. The vulnerability occurs when handling requests to the local status page. An exploit could allow the attacker to establish an interactive session to the device with elevated privileges. The attacker could then use the elevated privileges to further compromise the device or obtain additional configuration data from the device that is being exploited.

Cisco-Meraki MS, MR, and MX devices with firmware before 2014-09-24 allow physically proximate attackers to obtain shell access by opening a device's case and connecting a cable to a serial port, aka Cisco-Meraki defect ID 00302077.

Cisco-Meraki MS, MR, and MX devices with firmware before 2014-09-24 allow remote authenticated users to install arbitrary firmware by leveraging unspecified HTTP handler access on the local network, aka Cisco-Meraki defect ID 00478565.

Cisco-Meraki MS, MR, and MX devices with firmware before 2014-09-24 allow remote attackers to obtain sensitive credential information by leveraging unspecified HTTP handler access on the local network, aka Cisco-Meraki defect ID 00302012.

Cisco-Meraki MS, MR, and MX devices with firmware before 2014-09-24 allow remote attackers to execute arbitrary commands by leveraging knowledge of a cross-device secret and a per-device secret, and sending a request to an unspecified HTTP handler on the local network, aka Cisco-Meraki defect ID 00301991.
