Details about the vulnerabilities are as follows:
CVE-2025-20375: Cisco Unified CCX Arbitrary File Upload Vulnerability
A vulnerability in the web UI of Cisco Unified CCX could allow an authenticated, remote attacker to upload and execute arbitrary files.
This vulnerability is due to an insufficient input validation associated to specific UI features. An attacker could exploit this vulnerability by uploading a crafted file to the web UI. A successful exploit could allow the attacker to upload arbitrary files to a vulnerable system and execute them, gaining access to the underlying operating system. To exploit this vulnerability, the attacker must have valid administrative credentials.
Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.
Bug ID(s): CSCwq36645
CVE ID: CVE-2025-20375
Security Impact Rating (SIR): Medium
CVSS Base Score: 6.5
CVSS Vector: CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:NCVE-2025-20376: Cisco Unified CCX Remote Code Execution Vulnerability
A vulnerability in the web UI of Cisco Unified CCX could allow an authenticated, remote attacker to upload and execute arbitrary files.
This vulnerability is due to an insufficient input validation associated to file upload mechanisms. An attacker could exploit this vulnerability by uploading a malicious file to the web UI and executing it. A successful exploit could allow the attacker to execute arbitrary commands on the underlying system and elevate privileges to root. To exploit this vulnerability, the attacker must have valid administrative credentials.
Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.
Bug ID(s): CSCwq36567
CVE ID: CVE-2025-20376
Security Impact Rating (SIR): Medium
CVSS Base Score: 6.5
CVSS Vector: CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:NCVE-2025-20374: Cisco Unified CCX Arbitrary File Download Vulnerability
A vulnerability in the web UI of Cisco Unified CCX could allow an authenticated, remote attacker to perform a directory traversal and access arbitrary resources.
This vulnerability is due to an insufficient input validation associated to specific UI features. An attacker could exploit this vulnerability by sending a crafted request to the web UI. A successful exploit could allow the attacker to gain read access to arbitrary files on the underlying operating system. To exploit this vulnerability, the attacker must have valid administrative credentials.
Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.
Bug ID(s): CSCwq36596
CVE ID: CVE-2025-20374
Security Impact Rating (SIR): Medium
CVSS Base Score: 4.9
CVSS Vector: CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:N/A:NCVE-2025-20377: Cisco Unified Intelligence Center API Information Disclosure Vulnerability
A vulnerability in the API subsystem of Cisco Unified Intelligence Center could allow an authenticated, remote attacker to obtain sensitive information from an affected system.
This vulnerability is due to improper validation of requests to certain API endpoints. An attacker could exploit this vulnerability by sending a valid request to a specific API endpoint within the affected system. A successful exploit could allow a low-privileged user to view sensitive information on the affected system that should be restricted. To exploit this vulnerability, the attacker must have valid user credentials on the affected system.
Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.

SOFTWARE DOWNLOADS AND TECHNICAL SUPPORT
The Cisco Support and Downloads 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). 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, customers are advised to regularly consult the advisories 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) or their contracted maintenance providers.
