The vulnerabilities are not dependent on one another. Exploitation of one of the vulnerabilities is not required to exploit another vulnerability. In addition, a software release that is affected by one of the vulnerabilities may not be affected by the other vulnerabilities.

Details about the vulnerabilities are as follows:

CVE-2024-20537: Cisco ISE Authorization Bypass Vulnerability

A vulnerability in the web-based management interface of Cisco ISE could allow an authenticated, remote attacker to bypass the authorization mechanisms for specific administrative functions.

This vulnerability is due to a lack of server-side validation of Administrator permissions. An attacker could exploit this vulnerability by submitting a crafted HTTP request to an affected system. A successful exploit could allow the attacker to conduct administrative functions beyond their intended access level. To exploit this vulnerability, an attacker would need Read-Only Administrator credentials.

Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.

CVE-2024-20538: Cisco ISE Cross-Site Scripting Vulnerability

A vulnerability in the web-based management interface of Cisco ISE could allow an unauthenticated, remote attacker to conduct an XSS attack against a user of the interface.

This vulnerability exists because the web-based management interface does not sufficiently validate user-supplied input. An attacker could exploit this vulnerability by persuading a user of the interface on an affected system to click a crafted link. 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.

Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.

CVE-2024-20539: Cisco ISE Stored Cross-Site Scripting Vulnerability

A vulnerability in the web-based management interface of Cisco ISE could allow an authenticated, remote attacker to conduct a stored XSS attack against a user of the interface.

This vulnerability exists because the web-based management interface does not sufficiently validate user-supplied input. An attacker could exploit this vulnerability 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 this vulnerability, the attacker would need valid administrative credentials on an affected device.

Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.
