Summary
A vulnerability in the GUI of Cisco Identity Services Engine (ISE) could allow an authenticated, remote attacker with administrative privileges to upload files to an affected device. This is due to improper validation of the file copy function, enabling arbitrary file uploads.
Risk Assessment
An attacker with administrative privileges could upload malicious files, potentially leading to code execution or further system compromise. This could result in breaches of confidentiality, integrity, and availability.
Recommendation
Apply available security updates from Cisco for Cisco ISE. Restrict administrative access to trusted users and monitor for unusual file uploads.
Other vulnerabilities in Cisco Identity Services Engine
See all- CVE-2026-76460CriticalActively exploited
A vulnerability in the API of Cisco Identity Services Engine (ISE) could allow an unauthenticated, remote attacker to bypass authentication. This is due to insufficient authentication control on an API endpoint. An attacker could send a crafted request to gain unauthorized access to the device by bypassing the web-based management interface.
- CVE-2026-20284Critical
A vulnerability in the SXP REST API of Cisco ISE could allow an authenticated, remote attacker to conduct SQL injection attacks. This is due to insufficient validation of user-supplied input in REST API calls. A successful exploit could allow the attacker to view or modify data on the underlying database, and in single-node deployments could cause a DoS condition.
- CVE-2026-20237Critical
Vulnerability in Cisco Identity Services Engine (ISE) and ISE Passive Identity Connector (ISE-PIC) is due to improper input validation issues (CWE-20). It was discovered during an internal security review and addressed in a hardening release.
- CVE-2026-20211Critical
Vulnerability in Cisco ISE allows an authenticated remote attacker with high-privileged admin credentials to execute arbitrary commands on the underlying OS. It is due to insecure deserialization of Java objects. Single-node deployments may experience DoS.
- CVE-2026-20194Critical
Vulnerability in Cisco Identity Services Engine (ISE) and ISE Passive Identity Connector (ISE-PIC) is due to incorrect resource transfer between spheres (CWE-669). It was discovered during an internal security review and addressed in a hardening release.
- CVE-2026-20192Critical
Vulnerability in Cisco Identity Services Engine (ISE) and ISE Passive Identity Connector (ISE-PIC) is due to improper access control issues (CWE-284). It was discovered during an internal security review and addressed in a hardening release.
- CVE-2026-20176Critical
Vulnerability in Cisco ISE allows an authenticated remote attacker with high-privileged admin credentials to execute arbitrary commands on the underlying OS. It is due to insufficient validation of user-supplied input. Single-node deployments may experience DoS.
- CVE-2026-20130Critical
Vulnerability in Cisco Identity Services Engine (ISE) and ISE Passive Identity Connector (ISE-PIC) is due to improper neutralization of special elements (CWE-74). It was discovered during an internal security review and addressed in a hardening release.
- CVE-2026-20186Critical
A vulnerability in Cisco Identity Services Engine (ISE) allows an authenticated remote attacker to execute arbitrary commands on the underlying OS. The attacker needs at least Read Only Admin credentials and sends a crafted HTTP request.
- CVE-2026-20180Critical
A vulnerability in Cisco Identity Services Engine (ISE) allows an authenticated remote attacker to execute arbitrary commands on the underlying OS. The attacker needs at least Read Only Admin credentials and sends a crafted HTTP request.
Original NVD description (English source)
A vulnerability in the GUI of Cisco Identity Services Engine (ISE) could allow an authenticated, remote attacker with administrative privileges to upload files to an affected device. This vulnerability is due to improper validation of the file copy function. An attacker could exploit this vulnerability by sending a crafted file upload using the Cisco ISE GUI. A successful exploit could allow the attacker to upload arbitrary files to an affected system.
