"According to its self-reported version, Cisco Application Policy
Infrastructure Controller (APIC) is affected by following
vulnerability

  - A vulnerability in the web-based management interface of
    Cisco Application Policy Infrastructure Controller
    (APIC) could allow an authenticated, 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 is due to insufficient
    validation of user-supplied input by the web-based
    management interface. An attacker could exploit this
    vulnerability 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 affected interface or access sensitive,
    browser-based information. (CVE-2019-1838)
