Synopsis
The remote device is missing a vendor-supplied security patchDescription
The version of Cisco Firepower Management Center installed on the remote host is affected by a security bypass vulnerability in the web management interface that allows an authenticated, remote attacker to bypass security protections and upload malicious files to the affected system. This vulnerability is due to improper validation of files uploaded to the web management interface of Cisco FMC Software. An attacker could exploit this vulnerability by uploading a maliciously crafted file to a device running affected software. A successful exploit could allow the attacker to store malicious files on the device, which they could access later to conduct additional attacks, including executing arbitrary code on the affected device with root privileges.Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
