The version of Cisco Firerpower Management Center installed on the remote host is affected by multiple vulnerabilities as referenced in the cisco-sa-fmc-xss-openredir-TVPMWJyg advisory, as follows:
An authenticated, remote attacker can exploit a vulnerability in the web-based management interface by persuading a user to click a crafted link, in order to execute arbitrary script code. (CVE-2021-34763)
An unauthenticated, remote attacker can exploit a vulnerability in the web interface to redirect a user to a malicious web page. This is caused by improper input validation of HTTP request parameters.
(CE-2021-34764)
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
