CVE-2019-1838

Name of the Vulnerable Software and Affected Versions Cisco Application Policy Infrastructure Controller (APIC) versions prior to 14.1(1i)

Description 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 issue is due to insufficient validation of user-supplied input by the web-based management interface. An attacker could exploit this by persuading a user to click a crafted link, potentially allowing the execution of arbitrary script code in the context of the affected interface or access to sensitive, browser-based information.

Recommendations For versions prior to 14.1(1i), update to software version 14.1(1i) to fix the vulnerability. As a temporary workaround, consider restricting access to the web-based management interface to minimize the risk of exploitation. Avoid using the interface with untrusted input until the issue is resolved.
