This vulnerability is due to improper resource management when connection rates are high. Note: These vulnerabilities have been publicly discussed as NAT Slipstreaming.Ī vulnerability in the memory management of Cisco Adaptive Security Appliance (ASA) Software and Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. For more information about these vulnerabilities, see the Details section of this advisory. Multiple vulnerabilities in the Application Level Gateway (ALG) for the Network Address Translation (NAT) feature of Cisco Adaptive Security Appliance (ASA) Software and Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to bypass the ALG and open unauthorized connections with a host located behind the ALG. Reloading the affected device will restore all files within the web services file system.ġ8 Adaptive Security Appliance, Asa 5505, Asa 5505 Firmware and 15 more This vulnerability can not be used to obtain access to ASA or FTD system files or underlying operating system (OS) files.
This file system is enabled when the affected device is configured with either WebVPN or An圜onnect features. The attacker can only view and delete files within the web services file system. When the device is reloaded after exploitation of this vulnerability, any files that were deleted are restored. An exploit could allow the attacker to view or delete arbitrary files on the targeted system. An attacker could exploit this vulnerability by sending a crafted HTTP request containing directory traversal character sequences. The vulnerability is due to a lack of proper input validation of the HTTP URL. 26 Adaptive Security Appliance, Asa 5505, Asa 5505 Firmware and 23 moreĪ vulnerability in the web services interface of Cisco Adaptive Security Appliance (ASA) Software and Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to conduct directory traversal attacks and obtain read and delete access to sensitive files on a targeted system.
