Summary
Multiple vulnerabilities in the web-based management interface of Cisco Identity Services Engine (ISE) allow an authenticated remote attacker with administrative write privileges to conduct stored XSS or reflected XSS attacks against a user of the interface. These issues stem from insufficient sanitization of user-supplied data stored in web pages.
Risk Assessment
An attacker can trick a user into clicking a crafted link or viewing a malicious page, leading to script execution in the management interface context. This could result in theft of sensitive browser data or session hijacking.
Recommendation
Apply the security updates provided by Cisco for Cisco Identity Services Engine (ISE) immediately and restrict management interface access to trusted IP addresses. Additionally, implement content filtering and train users to recognize XSS attacks.
Original NVD description (English source)
Multiple vulnerabilities in the web-based management interface of Cisco Identity Services Engine (ISE) could allow an authenticated, remote attacker with administrative write privileges to conduct a stored cross-site scripting (XSS) attack or a reflected XSS attack against a user of the web-based management interface of an affected device. These vulnerabilities are due to insufficient sanitization of user-supplied data that is stored in the web page. An attacker could exploit these vulnerabilities by convincing a user of the interface to click a specific link or view an affected web page. The injected script code may be executed in the context of the web-based management interface or allow the attacker to access sensitive browser-based information.
