-
Multiple vulnerabilities in Cisco Identity Services Engine (ISE) and Cisco ISE Passive Identity Connector (ISE-PIC) could allow an authenticated, remote attacker to either disclose sensitive information or conduct a reflected cross-site scripting (XSS) attack.
For more information about these vulnerabilities, see the Details section of this advisory.
Cisco has released software updates that address these vulnerabilities. There are no workarounds that address these vulnerabilities.

Vulnerable Products
At the time of publication, these vulnerabilities affected Cisco ISE and Cisco ISE-PIC, regardless of device configuration.
For information about which Cisco software releases were vulnerable at the time of publication, see the Fixed Software section of this advisory. See the Details section in the bug ID(s) at the top of this advisory for the most complete and current information.
Products Confirmed Not Vulnerable
Only products listed in the Vulnerable Products section of this advisory are known to be affected by these vulnerabilities.
-
These vulnerabilities are not dependent on one another. Exploitation of one of the vulnerabilities is not required to exploit another vulnerability. In addition, a software release that is affected by one of the vulnerabilities may not be affected by the other vulnerabilities.
Details about the vulnerabilities are as follows:
CVE-2025-20289, CVE-2025-20303, and CVE-2025-20304: Cisco ISE Reflected XSS Vulnerabilities
Multiple vulnerabilities in the web-based management interface of Cisco ISE and Cisco ISE-PIC could allow an authenticated, remote attacker to conduct a reflected XSS attack against a user of the interface.
These vulnerabilities are due to insufficient validation of user-supplied input by the web-based management interface of an affected system. An attacker could exploit these vulnerabilities by injecting malicious code into specific pages of the interface. 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. To exploit these vulnerabilities, the attacker must have at least a low-privileged account on the affected device.
Cisco has released software updates that address these vulnerabilities. There are no workarounds that address these vulnerabilities.

CVSS Vector: CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:NCVE-2025-20305: Cisco ISE Information Disclosure Vulnerability
A vulnerability in the web-based management interface of Cisco ISE could allow an authenticated, remote attacker to obtain sensitive information from an affected device.
This vulnerability exists because certain files lack proper data protection mechanisms. An attacker with read-only Administrator privileges could exploit this vulnerability by performing actions where the results should only be viewable to a high-privileged user. A successful exploit could allow the attacker to view passwords that are normally not visible to read-only administrators.
Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.
Bug ID(s): CSCwo37181
CVE ID: CVE-2025-20305
SIR: Medium
CVSS Base Score: 4.3

-
There are no workarounds that address these vulnerabilities.
-
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.

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.
