Mitigation: Application Layer Protocol Inspection
Application layer protocol inspection is available beginning in Cisco IOS Software Release 7.2(1) for the Cisco ASA 5500 and 5500-X Series Adaptive Security Appliance, IOS Software Release 8.5 for the Cisco Catalyst 6500 Series ASA Services Module, and in IOS Software Release 4.0(1) for the Cisco Firewall Services Module. This advanced security feature performs deep packet inspection of traffic that transits the firewall. Administrators may construct an inspection policy for applications that require special handling through the configuration of inspection class maps and inspection policy maps, which are applied via a global or interface service policy. Application inspection will inspect both IPv4 and IPv6 packets matched in the class-map of the policy.
Additional information about application layer protocol inspection and the Modular Policy Framework (MPF) is in the Getting Started with Application Layer Protocol Inspection section of Book 2: Cisco ASA Series Firewall CLI Configuration Guide, 9.2.
Caution: Application layer protocol inspection will decrease firewall performance. Administrators are advised to test performance impact in a lab environment before this feature is deployed in production environments.
HTTP Application Inspection
For MS15-035, by using the HTTP inspection engine on the Cisco ASA 5500 and 5500-X Series Adaptive Security Appliances, Cisco 6500 Series ASA Services Modules, and the Cisco Firewall Services Module, administrators can configure regular expressions (regexes) for pattern matching and construct inspection class maps and inspection policy maps. These methods can help protect against specific vulnerabilities, such as the one described in this document, and other threats that may be associated with HTTP traffic. The following HTTP application inspection configuration uses the Cisco Modular Policy Framework (MPF) to create a policy for inspection of traffic on TCP ports 80, 3128, 8000, 8010, 8080, 8888, and 24326, which are the default ports for the Cisco IPS #WEBPORTS variable. The HTTP application inspection policy will drop connections where the HTTP response body contains any of the regexes that are configured to match the ActiveX control that is associated with these vulnerabilities.
Caution: The configured regexes can match text strings at any location in the body of an HTML response. Care should be taken to ensure that legitimate business applications that use matching text strings are not affected. Additional information about regex syntax is in Creating a Regular Expression.

Cisco Web and Email Security Appliance
Mitigation: Web Security
Cisco Web Security Appliances (WSA) can filter and protect corporate networks against web-based malware and spyware programs that can compromise corporate security and expose intellectual property. They operate as a proxy and can provide user- and group-based policies that filter certain URL categories, web content, web application visibility and control (AVC), websites based on web reputation and malware content. The WSA can also detect infected clients and stop malicious activity from going outside the corporate network using the L4 Traffic Monitor (L4TM). Policies can be configured using a web GUI. A CLI can also be used. The WSA includes protection for standard communication protocols, such as HTTP, HTTPS, FTP, and SOCKS.
To operate with network devices such as routers and firewalls, the WSA uses the Web Cache Communication Protocol (WCCP). With WCCP, content requests are transparently redirected to the WSA, which acts based on its configuration. Users do not need to configure a web-proxy in their browsers. In Cisco IOS Software, WCCP is enabled using the ip wccp commands and in the Cisco ASA using the wccp commands.
Cisco WSA can be used to mitigate MS15-035 by filtering web traffic based on the following:- low-reputation URL destinations;
- .emf file types
Mitigation: Email Security
Cisco Email Security Appliances (ESA) eliminate email spam and viruses, enforce corporate policy, and secure the network perimeter. They operate as an SMTP gateway, also known as a mail exchanger or MX. They can filter virus, spam, and phishing outbreaks. They also provide email encryption, message filtering, anti-spam services, antivirus services and more.
Cisco ESA can be used to mitigate MS15-035 by filtering messages based on an attachment type of .emf.
Filter actions allow messages to be dropped, bounced, archived, blind carbon copied or altered. Filters can also generate notifications.
For more information, see the Cisco AsyncOS Email Configuration Guide (PDF).Cisco Cloud Web Security
Mitigation: Cloud Web Security
Cisco Cloud Web Security (CWS) analyzes every web request and response to determine whether content is malicious, inappropriate, or acceptable based on the defined security policy. This offers effective protection against threats, including zero-day threats that would otherwise be successful. Cisco CWS can provide user and group-based policies that filter certain URL categories, web content, files and file types, web applications (AVC), websites based on web reputation and malware. It can inspect both HTTP and HTTPS traffic.
Starting in Cisco IOS 15.2MT on ISR-G2 routers and Cisco ASA Software Release 9.0, Cisco CWS can integrate transparently with Cisco IOS and Cisco ASA. In addition, starting with AnyConnect 3.0, CWS can be deployed with the AnyConnect client. CWS can also be deployed on end hosts as a Cisco Cloud Connector application.
Cisco CWS can be used to mitigate MS15-035 by filtering web traffic based on the following:- low-reputation URL destinations
- .emf file types
