CVE-2019-12637
CWE-79
CVSS Score:
5.4 AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N/E:X/RL:X/RC:X
Summary
o Multiple vulnerabilities in the web-based management interface of Cisco
Identity Services Engine (ISE) could allow an authenticated, remote
attacker to conduct cross-site scripting (XSS) attacks against a user of
the web-based management interface.
The vulnerabilities are due to insufficient validation of user-supplied
input that is processed by the web-based management interface. An attacker
could exploit these vulnerabilities by persuading a user of the interface
to click a crafted link. A successful exploit could allow the attacker to
execute arbitrary script code in the context of the interface or access
sensitive, browser-based information.
Cisco has released software updates that address these vulnerabilities.
There are no workarounds that address these vulnerabilities.
