Cisco Firepower Management Center Software XXE Injection (cisco-sa-fmc-xxe-MzPC4bYd)

medium Nessus Plugin ID 168327


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 tested version. It is, therefore, affected by a vulnerability in the module import function of the administrative interface of Cisco Firepower Management Center (FMC) Software due to insufficient validation of the XML syntax when importing a module. An authenticated, remote attacker could exploit this vulnerability by supplying a specially crafted XML file to the function. A successful exploit could allow the attacker to read sensitive data that would normally not be revealed.

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