Description

This security bulletin contains information about 1 security vulnerability.


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

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.
