Multiple vulnerabilities in Cisco Identity Services Engine (ISE) could allow a remote attacker to conduct a cross-site scripting (XSS) attack against a user of the web-based management interface, perform a path traversal attack, read and delete arbitrary files on an affected device, or conduct a server-side request forgery (SSRF) attack through the device.
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, 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.
-
The 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-2024-20525 and CVE-2024-20530: Cisco ISE Reflected Cross-Site Scripting Vulnerabilities
Two vulnerabilities in the web-based management interface of Cisco ISE could allow an unauthenticated, remote attacker to conduct an XSS attack against a user of the interface.
These vulnerabilities exist because the web-based management interface does not properly validate user-supplied input. An attacker could exploit these vulnerabilities by persuading a user of the interface 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.
Bug ID(s): CSCwk47423, CSCwk47454
CVE ID: CVE-2024-20525, CVE-2024-20530
Security Impact Rating (SIR): Medium
CVSS Base Score: 6.1
CVSS Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:NCVE-2024-20527, CVE-2024-20529, and CVE-2024-20532: Cisco ISE Arbitrary File Read and Delete Vulnerabilities
Three vulnerabilities in the API of Cisco ISE could allow an authenticated, remote attacker to read and delete arbitrary files on an affected device. To exploit these vulnerabilities, the attacker would need valid Super Admin credentials.
These vulnerabilities are due to insufficient validation of user-supplied parameters in API requests. An attacker could exploit these vulnerabilities by sending a crafted API request to an affected device. A successful exploit could allow the attacker to read or delete arbitrary files on the underlying operating system.

CVSS Vector: CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:L/A:NCVE-2024-20531: Cisco ISE XML External Entity Injection Vulnerability
A vulnerability in the API of Cisco ISE could allow an authenticated, remote attacker to read arbitrary files on the underlying operating system of an affected device and conduct a server-side request forgery (SSRF) attack through an affected device. To exploit this vulnerability, the attacker would need valid Super Admin credentials.
This vulnerability is due to improper handling of XML External Entity (XXE) entries when parsing XML input. An attacker could exploit this vulnerability by sending a crafted API request to an affected device. A successful exploit could allow the attacker to read arbitrary files on the underlying operating system or conduct an SSRF attack through the affected device.
Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.
Bug ID(s): CSCwk47465
CVE ID: CVE-2024-20531
Security Impact Rating (SIR): Medium
CVSS Base Score: 5.5
CVSS Vector: CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:L/I:L/A:NCVE-2024-20528: Cisco ISE Path Traversal Vulnerability
A vulnerability in the API of Cisco ISE could allow an authenticated, remote attacker to upload files to arbitrary locations on the underlying operating system of an affected device. To exploit this vulnerability, an attacker would need valid Super Admin credentials.
This vulnerability is due to insufficient validation of user-supplied parameters in API requests. An attacker could exploit this vulnerability by sending a crafted API request to an affected device. A successful exploit could allow the attacker to upload custom files to arbitrary locations on the underlying operating system, execute arbitrary code, and elevate privileges to root.
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.
