Cisco is urging organizations to implement its patch for a high severity directory traversal vulnerability that affected the web services interface of the Cisco Adaptive Security Appliance (ASA) Software and Cisco Firepower Threat Defense (FTD) Software firewall products and which is being actively exploited in the wild.

The vulnerability, CVE-2020-3452, stems from the “lack of proper input validation of URLs in HTTP requests processed by an affected device,” Cisco said in an advisory. “An attacker could exploit this vulnerability by sending a crafted HTTP request containing directory traversal character sequences to an affected device.”

If the exploit is successful, the attacker could view arbitrary files found within the web services file system on a device, the company said, urging affected organizations to update quickly since there are no workarounds for the flaw.
