CVE-2019-1941    

CWE-79

CVSS Score:
6.1  AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N/E:X/RL:X/RC:X

Summary

  o A vulnerability in the web-based management interface of Cisco Identity
    Services Engine (ISE) could allow an unauthenticated, remote attacker to
    conduct a cross-site scripting (XSS) attack against a user of the web-based
    management interface of an affected device.

    The vulnerability exists because the web-based management interface does
    not properly validate user-supplied input. An attacker could exploit this
    vulnerability by persuading a user to click a malicious 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.

    There are no workarounds that address this vulnerability.
