Cisco Identity Services Engine Stored Cross-Site Scripting Vulnerabilities [Multiple CVE’s]

CVE numbers CVE-2021-1603 and CVE-2021-1604 and CVE-2021-1605 and CVE-2021-1606 and CVE-2021-1607.

Multiple vulnerabilities in the web-based management interface of Cisco Identity Services Engine (ISE) could allow an authenticated, remote attacker to conduct a stored cross-site scripting (XSS) attack against a user.

These vulnerabilities exist because the web-based management interface does not sufficiently validate user-supplied input. 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 would need valid administrative credentials.

Cisco has released software updates that address these vulnerabilities. There are no workarounds that address these vulnerabilities.
