Synopsis
The remote device is missing a vendor-supplied security patchDescription
According to its self-reported version, Cisco Adaptive Security Appliance (ASA) Software is affected by a denial of service (DoS) vulnerability. This vulnerability exists in the Secure Copy (SCP) feature due to the use of an incorrect data type for a length variable. An authenticated, remote attacker can exploit this by initiating the transfer of a large file to an affected device via SCP, provided the attacker has valid privilege level 15 credentials on the affected device. This would cause the length variable to roll over, causing the system to stop responding.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.
