CVE-2018-0124
CWE-320
Summary
* A vulnerability in Cisco Unified Communications Domain Manager could allow
an unauthenticated, remote attacker to bypass security protections, gain
elevated privileges, and execute arbitrary code.
The vulnerability is due to insecure key generation during application
configuration. An attacker could exploit this vulnerability by using a
known insecure key value to bypass security protections by sending
arbitrary requests using the insecure key to a targeted application. An
exploit could allow the attacker to execute arbitrary code.
Cisco has released software updates that address this vulnerability. There
are no workarounds that address this vulnerability.

Products Confirmed Not Vulnerable
No other Cisco products are currently known to be affected 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
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
The vulnerability is fixed in Cisco Unified Communications Domain Manager
releases 11.5(2) and later.
The software can be downloaded from the Software Center on Cisco.com by
navigating to Products > Unified Communications > Call Control > Hosted
Collaboration > Hosted Collaboration Solution (HCS) > Hosted Collaboration
Solution Version 11.5 > Unified Communications Domain Manager (CUCDM)
Updates-11.5(2).
A patch for Cisco Unified Communications Domain Manager Classic release 8.1
(9) ER1 can be downloaded from the Software Center on Cisco.com by
navigating to Products > Unified Communications > Call Control > Hosted
Collaboration > Hosted Collaboration Solution (HCS) > Hosted Collaboration
Solution Version 11.5 > Unified Communications Domain Manager (CUCDM)
Updates-8.1.9ER1.

CVE-2018-0206
CWE-79
CVSS Score: Base 6.1
CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N/E:X/RL:X/RC:X
Summary
o A vulnerability in the web-based management interface of Cisco Unified
Communications Manager could allow an unauthenticated, remote attacker to
conduct a reflected cross-site scripting (XSS) attack against a user of the
web-based management interface of an affected device.
The vulnerability is due to insufficient validation of user-supplied input
by the web-based management interface of an affected device. An attacker
could exploit this vulnerability by persuading a user of the web-based
management interface to click a link that submits malicious input to the
interface. A successful exploit could allow the attacker to execute
arbitrary script code in the context of the interface or allow the attacker
to access sensitive browser-based information.
There are no workarounds that address this vulnerability.
