New! Vulnerability Priority Rating (VPR)

Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.

VPR Score: 3


The remote device is missing a vendor-supplied security patch


According to its self-reported version, Cisco Firepower Management Center is affected by multiple cross-site scripting (XSS) vulnerabilities in its web-based admin interface due to improper validation of user-supplied input before returning it to users. An unauthenticated, remote attacker can exploit these, by convincing a user to click a specially crafted URL, to execute arbitrary script code in a user's browser session.

Please see the included Cisco BIDs and Cisco Security Advisory for more information.

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