1) Path traversal (CVE-ID: CVE-2018-0300)

CWE-ID: CWE-22 - Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber


The vulnerability allows a remote authenticated attacker to execute arbitrary code on the target system.

The vulnerability exists in the process of uploading new application images to the Cisco Firepower 4100 Series Next-Generation Firewall (NGFW) and Firepower 9300 Security Appliance due to path traversal when insufficient validation during the application image upload process. A remote attacker can create an application image containing malicious code and install the image on the affected device using the CLI or web-based user interface (web UI), conduct path traversal attack, create or overwrite arbitrary files and execute arbitrary code with elevated privileges.
