Cisco Firepower Management Center Multiple Stored XSS (cisco-sa-fmc-stored-xss-djKfCzf2)

medium Nessus Plugin ID 149845
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.


The remote device is missing a vendor-supplied security patch.


The version of Cisco Firepower Management Center installed on the remote host is prior to 6.7.0. It is, therefore, affected by multiple vulnerabilities as referenced in the cisco-sa-fmc-stored-xss-djKfCzf2 advisory. Specifically, multiple vulnerabilities in the web-based management interface of Cisco Firepower Management Center (FMC) allow an authenticated, remote attacker to conduct a stored cross-site scripting (XSS) attack against a user of the interface of an affected system. The vulnerabilities exist because the web-based management interface does not properly validate user-supplied input. 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 affected interface or access sensitive, browser-based information.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
