A vulnerability in the web-based guest portal of Cisco Identity Services Engine (ISE) could allow an authenticated, remote attacker to conduct a cross-site scripting (XSS) attack against a user of the web-based management interface. The vulnerability is due to insufficient validation of user-supplied input that is processed by the web-based interface. An attacker could exploit this vulnerability 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 interface or access sensitive browser-based information. Cisco ISE software version 2.1 is affected.
A vulnerability in the web interface of Cisco Identity Services Engine (ISE) could allow an unauthenticated, remote attacker to trigger high CPU usage, resulting in a denial of service (DoS) condition. The vulnerability is due to improper handling of Secure Sockets Layer (SSL) renegotiation requests. An attacker could exploit this vulnerability by sending renegotiation requests at a high rate. An successful exploit could increase the resource usage on the system, eventually leading to a DoS condition. This vulnerability affects version 2.1.
A vulnerability in the web-based management interface of Cisco Identity Services Engine (ISE) could allow an authenticated, remote attacker to conduct a cross-site scripting (XSS) attack against a user of the web-based interface. The vulnerability is due to insufficient input validation of some parameters passed to the web-based management interface. An attacker could exploit this vulnerability by convincing a user of the interface to click a specific link. A successful exploit could allow the attacker to execute arbitrary script code in the context of the interface or allow the attacker to access sensitive browser-based information. For information about fixed software releases, consult the Cisco bug ID at https://quickview.cloudapps.cisco.com/quickview/bug/CSCvn64652. When considering software upgrades, customers are advised to regularly consult the advisories for Cisco products, which are available from the Cisco Security Advisories and Alerts page, to determine exposure and a complete upgrade solution.
A vulnerability in the Admin portal of Cisco Identity Services Engine (ISE) could allow an authenticated, remote attacker to obtain confidential information for privileged accounts. The vulnerability is due to the improper handling of confidential information. An attacker could exploit this vulnerability by logging into the web interface on a vulnerable system. An exploit could allow an attacker to obtain confidential information for privileged accounts. This information could then be used to impersonate or negatively impact the privileged account on the affected system.
A vulnerability in the logging component of Cisco Identity Services Engine could allow an unauthenticated, remote attacker to conduct cross-site scripting attacks. The vulnerability is due to the improper validation of requests stored in the system's logging database. An attacker could exploit this vulnerability by sending malicious requests to the targeted system. An exploit could allow the attacker to conduct cross-site scripting attacks when an administrator views the logs in the Admin Portal.
A vulnerability in the administrative web interface of Cisco Identity Services Engine (ISE) could allow an authenticated, remote attacker to gain additional privileges on an affected device. The vulnerability is due to improper controls on certain pages in the web interface. An attacker could exploit this vulnerability by authenticating to the device with an administrator account and sending a crafted HTTP request. A successful exploit could allow the attacker to create additional Admin accounts with different user roles. An attacker could then use these accounts to perform actions within their scope. The attacker would need valid Admin credentials for the device. This vulnerability cannot be exploited to add a Super Admin account.
A vulnerability in the Admin Portal of Cisco Identity Services Engine (ISE) could allow an authenticated, remote attacker to view saved passwords in plain text. The vulnerability is due to the incorrect inclusion of saved passwords when loading configuration pages in the Admin Portal. An attacker with read or write access to the Admin Portal could exploit this vulnerability by browsing to a page that contains sensitive data. An exploit could allow the attacker to recover passwords for unauthorized use and expose those accounts to further attack.
A vulnerability in the web-based management interface of Cisco Identity Services Engine (ISE) could allow an authenticated, remote attacker to execute arbitrary commands on the underlying operating system of an affected device with the privileges of the web server.
A vulnerability in the web-based management interface of Cisco Identity Services Engine (ISE) could allow an authenticated, remote attacker to execute arbitrary commands on the underlying operating system of an affected device with the privileges of the web server.
A vulnerability in the Extensible Authentication Protocol-Transport Layer Security (EAP-TLS) certificate validation during EAP authentication for the Cisco Identity Services Engine (ISE) could allow an unauthenticated, remote attacker to cause the ISE application server to restart unexpectedly, causing a denial of service (DoS) condition on an affected system. The vulnerability is due to incomplete input validation of the client EAP-TLS certificate. An attacker could exploit this vulnerability by initiating EAP authentication over TLS to the ISE with a crafted EAP-TLS certificate. A successful exploit could allow the attacker to restart the ISE application server, resulting in a DoS condition on the affected system. The ISE application could continue to restart while the client attempts to establish the EAP authentication connection. If an attacker attempted to import the same EAP-TLS certificate to the ISE trust store, it could trigger a DoS condition on the affected system. This exploit vector would require the attacker to have valid administrator credentials. The vulnerability affects Cisco ISE, Cisco ISE Express, and Cisco ISE Virtual Appliance.
