Summary
Cisco Unified Contact Center Express Remote Code Execution Vulnerabilities
Notes
Summary
Multiple vulnerabilities in the Java Remote Method Invocation (RMI) process of Cisco Unified Contact Center Express (Unified CCX) could allow an unauthenticated, remote attacker to upload arbitrary files, bypass authentication, execute arbitrary commands, and elevate privileges to root.
For more information about these vulnerabilities, see the Details ["#details"] section of this advisory.
Cisco has released software updates that address these vulnerabilities. There are no workarounds that address these vulnerabilities.
Vulnerable Products
These vulnerabilities affect Cisco Unified CCX, regardless of device configuration.
For information about which Cisco 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 these vulnerabilities.
Cisco has confirmed that these vulnerabilities do not affect the following Cisco products:
Packaged Contact Center Enterprise (Packaged CCE)
Unified Contact Center Enterprise (Unified CCE)
Details
The vulnerabilities are not dependent on one another. Exploitation of one of the vulnerabilities is not required to exploit the other vulnerability.
Details about the vulnerabilities are as follows:
CVE-2025-20354: Cisco Unified CCX Remote Code Execution Vulnerability
A vulnerability in the Java Remote Method Invocation (RMI) process of Cisco Unified CCX could allow an unauthenticated, remote attacker to upload arbitrary files and execute arbitrary commands with root permissions on an affected system.
This vulnerability is due to improper authentication mechanisms that are associated to specific Cisco Unified CCX features. An attacker could exploit this vulnerability by uploading a crafted file to an affected system through the Java RMI process. A successful exploit could allow the attacker to execute arbitrary commands on the underlying operating system and elevate privileges to root.
Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.
Bug ID(s): CSCwq36528 ["https://bst.cloudapps.cisco.com/bugsearch/bug/CSCwq36528"]
CVE ID: CVE-2025-20354
Security Impact Rating (SIR): Critical
CVSS Base Score: 9.8
CVSS Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
CVE-2025-20358: Cisco Unified CCX Editor Authentication Bypass Vulnerability
A vulnerability in the Contact Center Express (CCX) Editor application of Cisco Unified CCX could allow an unauthenticated, remote attacker to bypass authentication and obtain administrative permissions pertaining to script creation and execution.
This vulnerability is due to improper authentication mechanisms in the communication between the CCX Editor and an affected Unified CCX server. An attacker could exploit this vulnerability by redirecting the authentication flow to a malicious server and tricking the CCX Editor into believing the authentication was successful. A successful exploit could allow the attacker to create and execute arbitrary scripts on the underlying operating system of an affected Unified CCX server, as an internal non-root user account.
Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.
Bug ID(s): CSCwq36573 ["https://bst.cloudapps.cisco.com/bugsearch/bug/CSCwq36573"]
CVE ID: CVE-2025-20358
Security Impact Rating (SIR): Critical
CVSS Base Score: 9.4
CVSS Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:L
Workarounds
There are no workarounds that address these vulnerabilities.
Fixed Software
Cisco considers any workarounds and mitigations to be temporary solutions until an upgrade to a fixed software release is available. To fully remediate these vulnerabilities and avoid future exposure as described in this advisory, Cisco strongly recommends that customers upgrade to the fixed software indicated in this advisory.
Fixed Releases
In the following table, the left column lists Cisco software releases. The right column indicates whether a release is affected by the vulnerabilities that are described in this advisory and the first release that includes the fix for these vulnerabilities. Customers are advised to upgrade to an appropriate fixed software release ["https://sec.cloudapps.cisco.com/security/center/resources/security_vulnerability_policy.html#fixes"] as indicated in this section.
Cisco Unified CCX Release First Fixed Release 12.5 SU3 and earlier 12.5 SU3 ES07 15.0 15.0 ES01

SOFTWARE DOWNLOADS AND TECHNICAL SUPPORT
The Cisco Support and Downloads ["https://www.cisco.com/c/en/us/support/index.html"] page on Cisco.com provides information about licensing and downloads. This page can also display customer device support coverage for customers who use the My Devices tool. Please note that customers may download only software that was procured from Cisco directly or through a Cisco authorized reseller or partner and for which the license is still valid.
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 Technical Assistance Center (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.
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 ["https://www.cisco.com/go/psirt"] for the relevant Cisco products 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) ["https://www.cisco.com/c/en/us/support/web/tsd-cisco-worldwide-contacts.html"] or their contracted maintenance providers.
