CWEs: CWE-79
Summary
o 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.
