Cisco Identity Services Engine Vulnerabilities
CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:L/E:X/RL:X/RC:X
-
Multiple vulnerabilities in Cisco Identity Services Engine (ISE) could allow an authenticated, remote attacker to upload malicious files to the web root of the application or conduct a cross-site scripting (XSS) attack against a user of the web-based management interface of an affected device. To exploit these vulnerabilities, an attacker must have valid credentials on an affected 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.
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 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-2023-20272: Cisco ISE Arbitrary File Write Vulnerability
A vulnerability in the web-based management interface of Cisco ISE could allow an authenticated, remote attacker to upload malicious files to the web root of the application.
This vulnerability is due to insufficient file input validation. An attacker could exploit this vulnerability by uploading a malicious file to the web interface. A successful exploit could allow the attacker to replace files and gain access to sensitive server-side information.
Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.
Bug ID(s): CSCwc45768
CVE ID: CVE-2023-20272
Security Impact Rating (SIR): Medium
CVSS Base Score: 6.7
CVSS Vector: CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:LCVE-2023-20208: Cisco ISE XSS Vulnerability
A vulnerability in the web-based management interface of Cisco ISE could allow an authenticated, remote attacker to conduct an XSS attack against a user of the web-based management interface of an affected device.
This vulnerability exists because the web-based management interface does not properly validate user-supplied input. An attacker could exploit this vulnerability 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 interface or access sensitive, browser-based information. To exploit this vulnerability, an attacker would need valid administrative credentials.
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.
