Cisco Web Security Appliance Native FTP Denial of Service Vulnerability
vendor_cisco·2016-06-27·CVSS 5.0
CVE-2016-1440 [MEDIUM] CWE-399 Cisco Web Security Appliance Native FTP Denial of Service Vulnerability
Cisco Web Security Appliance Native FTP Denial of Service Vulnerability
A vulnerability in the native pass-through FTP functionality of the Cisco Web Security Appliance (WSA) could allow an unauthenticated, remote attacker to cause a partial denial of service (DoS) condition due to high CPU utilization.
The vulnerability is due to how the FTP client terminates the FTP control connection when the data transfer is complete. An attacker could exploit this vulnerability by initiating FTP connections through the WSA. An exploit could allow the attacker to cause high CPU utilization of the Cisco WSA proxy process, causing a partial DoS condition. Successful exploitation depends on the FTP client the attacker uses and how that FTP client closes the FTP control connection.
Cisco has released so
