Summary
Cisco Adaptive Security Appliance (ASA) Software and Firepower Threat Defense (FTD) Software are affected when their web services interface is enabled through WebVPN or AnyConnect features. An unauthenticated remote attacker could exploit this flaw to read arbitrary files within the web services file system, though it does not grant access to system or operating system files.

Read the original description
A 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 read sensitive files on a targeted system. The vulnerability is due to a lack of proper input validation of URLs in HTTP requests processed by an affected device. An attacker could exploit this vulnerability by sending a crafted HTTP request containing directory traversal character sequences to an affected device. A successful exploit could allow the attacker to view arbitrary files within the web services file system on the targeted device. The web services file system is enabled when the affected device is configured with either WebVPN or AnyConnect features. This vulnerability cannot be used to obtain access to ASA or FTD system files or underlying operating system (OS) files.
