Summary
Cisco IOS XE Software Filesystem Exhaustion Denial of Service Vulnerability

Notes

Summary
A vulnerability in the filesystem resource management code of Cisco IOS XE Software could allow an unauthenticated, remote attacker to exhaust filesystem resources on an affected device and cause a denial of service (DoS) condition. The vulnerability is due to ineffective management of the underlying filesystem resources. An attacker could exploit this vulnerability by performing specific actions that result in messages being sent to specific operating system log files. A successful exploit could allow the attacker to exhaust available filesystem space on an affected device. This could cause the device to crash and reload, resulting in a DoS condition for clients whose network traffic is transiting the device. Upon reload of the device, the impacted filesystem space is cleared, and the device will return to normal operation. However, continued exploitation of this vulnerability could cause subsequent forced crashes and reloads, which could lead to an extended DoS 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-20190925-iosxe-fsdos ["https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190925-iosxe-fsdos"] This advisory is part of the September 25, 2019, release of the Cisco IOS and IOS XE Software Security Advisory Bundled Publication, which includes 12 Cisco Security Advisories that describe 13 vulnerabilities. For a complete list of the advisories and links to them, see Cisco Event Response: September 2019 Semiannual Cisco IOS and IOS XE Software Security Advisory Bundled Publication ["https://sec.cloudapps.cisco.com/security/center/viewErp.x?alertId=ERP-72547"].
Vulnerable Products
This vulnerability affects Cisco devices that are running a vulnerable release of Cisco IOS XE Software. For information about which Cisco IOS XE Software releases are vulnerable, see the Fixed Software ["#fs"] section of this advisory.
Products Confirmed Not Vulnerable
Only products listed in the Vulnerable Products ["#vp"] section of this advisory are known to be affected by this vulnerability. Cisco has confirmed that this vulnerability does not affect Cisco IOS Software, Cisco IOS XR Software, or Cisco NX-OS Software.
Indicators of Compromise
Administrators can monitor the affected filesystem to determine potential impact by using the show platform software mount | include File|tmpfs command. As the Use % value approaches 100 percent, the potential for impact increases. The following example shows the output of the show platform software mount | include File|tmpfs command: Router#show platform software mount | include File|tmpfs Filesystem Used Available Use % Mounted on devtmpfs 0 1586628 0% /dev tmpfs 3172 1592612 1% /dev/shm tmpfs 8236 1587548 1% /run . . . Note: The filesystem of interest is tmpfs and not devtmpfs. If the Use % value for the tmpfs filesystem is higher than expected, customers should contact the Cisco Technical Assistance Center (TAC) for assistance in determining the root cause.
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 ["https://sec.cloudapps.cisco.com/security/center/resources/security_vulnerability_policy.html#fixes"], 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. Cisco IOS and IOS XE Software To help customers determine their exposure to vulnerabilities in Cisco IOS and IOS XE Software, Cisco provides a tool, the Cisco IOS Software Checker ["https://sec.cloudapps.cisco.com/security/center/softwarechecker.x"], that identifies any Cisco Security Advisories that impact a specific software release and the earliest release that fixes the vulnerabilities described in each advisory (“First Fixed”). If applicable, the tool also returns the earliest release that fixes all the vulnerabilities described in all the advisories identified (“Combined First Fixed”). Customers can use this tool to perform the following tasks: Initiate a search by choosing one or more releases from a drop-down list or uploading a file from a local system for the tool to parse Enter the output of the show version command for the tool to parse Create a custom search by including all previously published Cisco Security Advisories, a specific advisory, or all advisories in the most recent bundled publication To determine whether a release is affected by any published Cisco Security Advisory, use the Cisco IOS Software Checker ["https://sec.cloudapps.cisco.com/security/center/softwarechecker.x"] on Cisco.com or enter a Cisco IOS or IOS XE Software release—for example, 15.1(4)M2 or 3.13.8S—in the following field: By default, the Cisco IOS Software Checker includes results only for vulnerabilities that have a Critical or High Security Impact Rating (SIR). To include results for Medium SIR vulnerabilities, use the Cisco IOS Software Checker on Cisco.com and check the Medium check box in the Impact Rating drop-down list. For a mapping of Cisco IOS XE Software releases to Cisco IOS Software releases, refer to the Cisco IOS XE 2 Release Notes ["https://www.cisco.com/c/en/us/td/docs/ios/ios_xe/2/release/notes/rnasr21/rnasr21_gen.html#wp3000032"], Cisco IOS XE 3S Release Notes ["https://www.cisco.com/c/en/us/td/docs/ios/ios_xe/3/release/notes/asr1k_rn_3s_rel_notes/asr1k_rn_3s_sys_req.html#wp3069754"], or Cisco IOS XE 3SG Release Notes ["https://www.cisco.com/c/en/us/td/docs/switches/lan/catalyst4500/release/note/OL_24726.html#pgfId-2570252"], depending on the Cisco IOS XE Software release.
