First Published: 2019 May 1 16:00 GMT
Version 1.0: Final

CVE-2019-1807
CWE-384
CVSS Score:
7.6 AV:N/AC:L/PR:L/UI:R/S:U/C:H/I:H/A:L/E:X/RL:X/RC:X
Summary
o A vulnerability in the session management functionality of the web UI for
the Cisco Umbrella Dashboard could allow an authenticated, remote attacker
to access the Dashboard via an active, user session.
The vulnerability exists due to the affected application not invalidating
an existing session when a user authenticates to the application and
changes the users credentials via another authenticated session. An
attacker could exploit this vulnerability by using a separate,
authenticated, active session to connect to the application through the web
UI. A successful exploit could allow the attacker to maintain access to the
dashboard via an authenticated user's browser session.
Cisco has released software updates that address this vulnerability. There
are no workarounds that address this vulnerability.

Dashboard. No user action is required.
Products Confirmed Not Vulnerable

are known to be affected by this vulnerability.
Workarounds
o There are no workarounds that address this vulnerability.
Fixed Software
o 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
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 , 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
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
Cisco has addressed this vulnerability in the Cisco Umbrella Dashboard. No
user action is required.
