Summary
Container Privilege Escalation Vulnerability Affecting Cisco Products: February 2019

Notes

Summary
A vulnerability in the Open Container Initiative runc CLI tool used by multiple products could allow an unauthenticated, remote attacker to escalate privileges on a targeted system. The vulnerability exists because the affected software improperly handles file descriptors related to /proc/self/exe. An attacker could exploit the vulnerability either by persuading a user to create a new container using an attacker-controlled image or by using the docker exec command to attach into an existing container that the attacker already has write access to. A successful exploit could allow the attacker to overwrite the host's runc binary file with a malicious file, escape the container, and execute arbitrary commands with root privileges on the host system. This advisory will be updated as additional information becomes available. This advisory is available at the following link: https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190215-runc ["https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190215-runc"]
Affected Products
The Vulnerable Products ["#vp"] section will include Cisco bug IDs for each affected product or service. The bugs will be accessible through the Cisco Bug Search Tool ["https://bst.cloudapps.cisco.com/bugsearch/bug/BUGID"] and contain additional platform-specific information, including workarounds (if available) and fixed software releases.
Vulnerable Products
The following table lists Cisco products that are affected by the vulnerability that is described in this advisory. If a future release date is indicated for software, the date provided represents an estimate based on all information known to Cisco as of the Last Updated date at the top of the advisory. Availability dates are subject to change based on a number of factors, including satisfactory testing results and delivery of other priority features and fixes. If no version or date is listed for an affected component (indicated by a blank field and/or an advisory designation of Interim), Cisco is continuing to evaluate the fix and will update the advisory as additional information becomes available. After the advisory is marked Final, customers should refer to the associated Cisco bug(s) for further details.
