According to its self-reported version, Cisco IOS XE Software is affected by an arbitrary file write vulnerability in the web-based user interface (web UI) due to insufficient input validation of HTTP requests that are sent to the web UI of the affected software. An authenticated, remote attacker can exploit this, by sending a malicious HTTP request to the web UI of the affected software, in order to write arbitrary files to the operating system of an affected device.
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 number.
