CVE-2015-6386

TITLE

Cisco Web Security Pass-through that runs on the appliance device software FTP Service disruption in functionality (DoS) Vulnerabilities

Trust: 0.8

sources: JVNDB: JVNDB-2015-006057

DESCRIPTION

The passthrough FTP feature on Cisco Web Security Appliance (WSA) devices with software 8.0.7-142 and 8.5.1-021 allows remote attackers to cause a denial of service (CPU consumption) via FTP sessions in which the control connection is ended after data transfer, aka Bug ID CSCut94150. The Cisco Web Security Appliance is a secure Web gateway that integrates malware protection, application visualization control, policy control, and more on a single platform. This vulnerability can be exploited by an unauthenticated remote attacker after launching an FTP connection through the WSA. Causes high CPU utilization, resulting in a denial of service. This vulnerability is triggered when the FTP client interrupts the FTP control connection when the data transfer is complete. Attackers can exploit this issue to cause a denial-of-service condition, denying service to legitimate users. This issue is being tracked by Cisco Bug ID CSCut94150
