CVE Names: CVE-2021-1380 CVE-2021-1407 CVE-2021-1408 CVE-2021-1409
CWEs: CWE-89
Summary
o Multiple vulnerabilities in the web-based management interface of Cisco
Unified Communications Manager (Unified CM), Cisco Unified Communications
Manager IM & Presence Service (Unified CM IM&P), Cisco Unified
Communications Manager Session Management Edition (Unified CM SME), and
Cisco Unity Connection could allow an unauthenticated, remote attacker to
conduct a cross-site scripting (XSS) attack against an interface user.
These vulnerabilities exist because the web-based management interface does
not properly validate user-supplied input. An attacker could exploit these
vulnerabilities by persuading an interface user to click a crafted link. A
successful exploit could allow the attacker to execute arbitrary script
code in the context of the affected interface or access sensitive
browser-based information.
Cisco has released software updates that address these vulnerabilities.
There are no workarounds that address these vulnerabilities.

Cisco Unified Communications Products Remote Code Execution Vulnerability
Priority: High
Advisory ID: cisco-sa-cucm-rce-pqVYwyb
First Published: 2021 April 7 16:00 GMT
Version 1.0: Final
Workarounds: No workarounds available
Cisco Bug IDs: CSCvu56491 CSCvv35203 CSCvv41616 CSCvv59434
CVE Names: CVE-2021-1362
CWEs: CWE-94
Summary
o A vulnerability in the SOAP API endpoint of Cisco Unified Communications
Manager, Cisco Unified Communications Manager Session Management Edition,
Cisco Unified Communications Manager IM & Presence Service, Cisco Unity
Connection, and Cisco Prime License Manager could allow an authenticated,
remote attacker to execute arbitrary code on an affected device.
This vulnerability is due to improper sanitization of user-supplied input.
An attacker could exploit this vulnerability by sending a SOAP API request
with crafted parameters to an affected device. A successful exploit could
allow the attacker to execute arbitrary code with root privileges on the
underlying Linux operating system of the affected device.
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://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-cucm-rce-pqVYwyb
Affected Products
o Vulnerable Products
This vulnerability affects the following Cisco products if they are running
a vulnerable software release:
Unified Communications Manager (Unified CM)
Unified Communications Manager Session Management Edition (Unified CM
SME)
Unified Communications Manager IM & Presence Service (Unified CM IM&P)
Unity Connection
Prime License Manager
For information about which Cisco software releases are vulnerable, see the
Fixed Software section of this advisory.
Products Confirmed Not Vulnerable
Only products listed in the Vulnerable Products section of this advisory
are known to be affected by this vulnerability.
Cisco has confirmed that this vulnerability does not affect Cisco Emergency
Responder.
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 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.
