CVE-2019-1941
Cisco Identity Services Engine Cross-Site Scripting Vulnerability
Published 2019-07-17 · Modified
6.1EPSS 0.013
CVE-2018-0091
A vulnerability in the web-based management interface of Cisco Identity Services Engine (ISE) could allow an unauthenticated, remote attacker to conduct a Document Object Model (DOM) cross-site scripting (XSS) attack against a user of the web-based management interface of an affected device. The vulnerability is due to insufficient validation of user-supplied input by the web-based management interface. An attacker could exploit this vulnerability by persuading a user of the interface to click a malicious 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. Cisco Bug IDs: CSCvf73922.

CVE-2022-20966
A vulnerability in the web-based management interface of Cisco Identity Services Engine could allow an authenticated, remote attacker to conduct cross-site scripting attacks against other users of the application web-based management interface. This vulnerability is due to improper validation of input to an application feature before storage within the web-based management interface. An attacker could exploit this vulnerability by creating entries within the application interface that contain malicious HTML or script code. A successful exploit could allow the attacker to store malicious HTML or script code within the application interface for use in further cross-site scripting attacks. Cisco has not yet released software updates that address this vulnerability.

CVE-2025-20303
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.

CVE-2022-20965
A vulnerability in the web-based management interface of Cisco Identity Services Engine could allow an authenticated, remote attacker to take privileges actions within the web-based management interface. This vulnerability is due to improper access control on a feature within the web-based management interface of the affected system. An attacker could exploit this vulnerability by accessing features through direct requests, bypassing checks within the application. A successful exploit could allow the attacker to take privileged actions within the web-based management interface that should be otherwise restricted. {{value}} ["%7b%7bvalue%7d%7d"])}]]

CVE-2022-20937
A vulnerability in a feature that monitors RADIUS requests on Cisco Identity Services Engine (ISE) Software could allow an unauthenticated, remote attacker to negatively affect the performance of an affected device. This vulnerability is due to insufficient management of system resources. An attacker could exploit this vulnerability by taking actions that cause Cisco ISE Software to receive specific RADIUS traffic. A successful and sustained exploit of this vulnerability could allow the attacker to cause reduced performance of the affected device, resulting in significant delays to RADIUS authentications. There are workarounds that address this vulnerability.

CVE-2023-20194
A vulnerability in the ERS API of Cisco ISE could allow an authenticated, remote attacker to read arbitrary files on the underlying operating system of an affected device. To exploit this vulnerability, an attacker must have valid Administrator-level privileges on the affected device. This vulnerability is due to improper privilege management in the ERS API. An attacker could exploit this vulnerability by sending a crafted request to an affected device. A successful exploit could allow the attacker to elevate their privileges beyond the sphere of their intended access level, which would allow them to obtain sensitive information from the underlying operating system. Note: The ERS is not enabled by default. To verify the status of the ERS API in the Admin GUI, choose Administration > Settings > API Settings > API Service Settings.

CVE-2025-20305
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.
