Cisco Firepower Management Center Software Multiple XSS (cisco-sa-fmc-xss-yT8LNSeA)

medium Nessus Plugin ID 149325
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 (FMC) installed on the remote host is affected by multiple cross-site scripting (XSS) vulnerabilities due to insufficient validation of user-supplied input before returning it to users. An unauthenticated, remote attacker can exploit this, by convincing a user to click a specially crafted URL, to execute arbitrary script code in a user's browser session.

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


Upgrade to the relevant fixed version referenced in Cisco bug IDs CSCvw93272, CSCvw93276, CSCvw93282, CSCvw93513.
