Vulnerable Products
At the time of publication, these vulnerabilities affected Cisco Secure FMC Software when configured for multitenancy using domains.
For information about which Cisco software releases are vulnerable, see the Fixed Software section of this advisory.
Determine Whether Multitenancy Using Domains Is Configured
To determine whether Cisco Secure FMC Software is configured for multitenancy using domains, see the Domain Management chapter of the Firepower Management Center Configuration Guide for the installed software release.
Products Confirmed Not Vulnerable
Only products listed in the Vulnerable Products 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:
- Secure Firewall Adaptive Security Appliance (ASA) Software
- Secure Firewall Threat Defense (FTD) Software
-
The vulnerabilities are not dependent on one another. Exploitation of one of the vulnerabilities is not required to exploit the other vulnerability. In addition, a software release that is affected by one of the vulnerabilities may not be affected by the other vulnerability.
Details about the vulnerabilities are as follows:
CVE-2025-20301: Cisco Secure FMC Software Troubleshoot File Access Authorization Bypass Vulnerability
A vulnerability in the web-based management interface of Cisco Secure FMC Software could allow an authenticated, low-privileged, remote attacker to access troubleshoot files for a different domain.
This vulnerability is due to missing authorization checks. An attacker could exploit this vulnerability by directly accessing a troubleshoot file for a different domain that is managed on the same Cisco Secure FMC instance. A successful exploit could allow the attacker to retrieve a troubleshoot file for a different domain, which could allow the attacker to access sensitive information contained in the troubleshoot file.
Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.
Bug ID(s): CSCwn18575
CVE ID: CVE-2025-20301
Security Impact Rating (SIR): Medium
CVSS Base Score: 6.5
CVSS Vector: CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:NCVE-2025-20302: Cisco Secure FMC Software Report Access Authorization Bypass Vulnerability
A vulnerability in the web-based management interface of Cisco Secure FMC Software could allow an authenticated, low-privileged, remote attacker to retrieve a generated report from a different domain.
This vulnerability is due to missing authorization checks. An attacker could exploit this vulnerability by directly accessing a generated report file for a different domain that is managed on the same Cisco Secure FMC instance. A successful exploit could allow the attacker to access a previously run report for a different domain, which could allow an attacker to read activity recorded in that domain.
Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.

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.
Cisco Secure Firewall ASA, Secure FMC, and Secure FTD Software
To help customers determine their exposure to vulnerabilities in Cisco Secure Firewall ASA, Secure FMC, and Secure FTD Software, Cisco provides the Cisco Software Checker. This tool identifies any Cisco security advisories that impact a specific software release and the earliest release that fixes the vulnerabilities that are described in each advisory (“First Fixed”). If applicable, the tool also returns the earliest release that fixes all the vulnerabilities that are described in all the advisories that the Software Checker identifies (“Combined First Fixed”).
To use the tool, go to the Cisco Software Checker page and follow the instructions. Alternatively, use the following form to search for vulnerabilities that affect a specific software release. To use the form, follow these steps:
- Choose which advisories the tool will search—all advisories, only advisories with a Critical or High Security Impact Rating (SIR), or only this advisory.
- Choose the appropriate software.
- Choose the appropriate platform.
- Enter a release number—for example, 9.20.3.4 for Cisco Secure Firewall ASA Software or 7.4.2 for Cisco Secure FTD Software.
- Click Check.
