Summary
Cisco Firepower Detection Engine Secure Sockets Layer Denial of Service Vulnerability

Notes

Summary
A vulnerability in the Secure Sockets Layer (SSL) packet reassembly functionality of the detection engine in Cisco Firepower System Software could allow an unauthenticated, remote attacker to cause the detection engine to consume excessive system memory on an affected device, which could cause a denial of service (DoS) condition. The vulnerability is due to the affected software improperly handling changes to SSL connection states. An attacker could exploit this vulnerability by sending crafted SSL connections through an affected device. A successful exploit could allow the attacker to cause the detection engine to consume excessive system memory on the affected device, which could cause a DoS condition. The device may need to be reloaded manually to recover from this condition. Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability. This advisory is available at the following link: https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20180418-fpsnort ["https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20180418-fpsnort"]
Vulnerable Products
This vulnerability affects Cisco Firepower System Software Releases 6.0.0 and later, if the software is configured as described in this section and the software is running on any of the following Cisco products: Adaptive Security Appliance (ASA) 5500-X Series Firewalls with FirePOWER Services Adaptive Security Appliance (ASA) 5500-X Series Next-Generation Firewalls Advanced Malware Protection (AMP) for Networks, 7000 Series Appliances Advanced Malware Protection (AMP) for Networks, 8000 Series Appliances Firepower 4100 Series Appliances FirePOWER 7000 Series Appliances FirePOWER 8000 Series Appliances Firepower 9300 Series Security Appliances Firepower Threat Defense for Integrated Services Routers (ISRs) Firepower Threat Defense Virtual for VMware Industrial Security Appliance 3000 Sourcefire 3D System Appliances A device is vulnerable if the software is configured to pass encrypted traffic that matches an SSL policy rule or has a default rule action of Do not decrypt. Determining the Cisco Firepower System Software Release To determine which Cisco Firepower System Software release is running on a device, administrators can log in to the device and use the show version command in the CLI. The following example shows the output of the command for a device that is running Release 6.2.0: > show version ---------------------[ ftd ]--------------------- Model : Cisco ASA5525-X Threat Defense (75) Version 6.2.0 (Build 362) UUID : 2849ba3c-ecb8-11e6-98ca-b9fc2975893c Rules update version : 2017-03-15-001-vrt VDB version : 279 ----------------------------------------------------
Products Confirmed Not Vulnerable
No other Cisco products are currently known to be affected by this vulnerability. Cisco has confirmed that this vulnerability does not affect the following Cisco products: Adaptive Security Appliance (ASA) Software Firepower Management Center Intrusion Prevention System (IPS) Software Meraki MX Security Appliances Next-Generation Intrusion Prevention System (NGIPSv) for VMware Snort IPS for Integrated Services Routers (ISRs)
Details
This vulnerability could cause the Snort process to exhaust system memory on an affected device and restart. While the Snort process is restarting, threat detection could be bypassed, inspection of all network traffic could fail, or network traffic could be prevented from passing through the device, depending on the platform and device configuration. On Cisco FirePOWER platforms: Passive and bypass interfaces will bypass inspection and traffic will pass through the device. Routed, switched, and nonbypass interfaces will drop the traffic; traffic will not pass through the device. Cisco Firepower Threat Defense (FTD) Software will drop the traffic; traffic will not pass through the device. On Cisco ASA 5500-X Series Firewalls with FirePOWER Services, traffic will bypass threat detection and will not be dropped, if the sfr fail-open CLI command is supported and configured on the ASA.
Indicators of Compromise
Exploitation of this vulnerability could cause the following error message to appear in the /var/log/messages system log file for an affected device: Firepower-module2 kernel: [109568.659049] snort invoked oom-killer: gfp_mask=0xd0, order=0, oom_score_adj=0 Contact the Cisco Technical Assistance Center (TAC) if additional assistance is required to determine whether the device has been compromised by this vulnerability.
Workarounds
There are no workarounds that address this vulnerability.
Fixed Software
Cisco has released free software updates that address the vulnerability described in this advisory. Customers may only install and expect support for software versions and feature sets for which they have purchased a license. By installing, downloading, accessing, or otherwise using such software upgrades, customers agree to follow the terms of the Cisco software license: https://www.cisco.com/c/en/us/products/end-user-license-agreement.html ["https://www.cisco.com/c/en/us/products/end-user-license-agreement.html"] Additionally, customers may only download software for which they have a valid license, procured from Cisco directly, or through a Cisco authorized reseller or partner. In most cases this will be a maintenance upgrade to software that was previously purchased. Free security software updates do not entitle customers to a new software license, additional software feature sets, or major revision upgrades. When considering software upgrades, customers are advised to regularly consult the advisories for Cisco products, which are available from the Cisco Security Advisories and Alerts page ["https://www.cisco.com/go/psirt"], to determine exposure and a complete upgrade solution. In all cases, customers should ensure that the devices to be upgraded contain sufficient memory and confirm that current hardware and software configurations will continue to be supported properly by the new release. If the information is not clear, customers are advised to contact the Cisco Technical Assistance Center (TAC) or their contracted maintenance providers. Customers Without Service Contracts Customers who purchase directly from Cisco but do not hold a Cisco service contract and customers who make purchases through third-party vendors but are unsuccessful in obtaining fixed software through their point of sale should obtain upgrades by contacting the Cisco TAC: https://www.cisco.com/c/en/us/support/web/tsd-cisco-worldwide-contacts.html ["https://www.cisco.com/c/en/us/support/web/tsd-cisco-worldwide-contacts.html"] Customers should have the product serial number available and be prepared to provide the URL of this advisory as evidence of entitlement to a free upgrade. Fixed Releases Customers should upgrade to an appropriate release as indicated in the table in this section. To help ensure a complete upgrade solution, consider that this advisory is part of a collection that includes the following advisories: cisco-sa-20180418-fp2100 ["https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20180418-fp2100"]: Cisco Firepower 2100 Series Security Appliances IP Fragmentation Denial of Service Vulnerability cisco-sa-20180418-fpsnort ["https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20180418-fpsnort"]: Cisco Firepower Detection Engine Secure Sockets Layer Denial of Service Vulnerability In the following table, the left column lists releases of Cisco software.
