Cisco Firepower Management Center Software and Firepower Threat Defense Path Traversal Vulnerability

A vulnerability in the sftunnel functionality of Cisco Secure Firewall Management Center (FMC) Software and Cisco Secure Firewall Threat Defense (FTD) Software could allow an authenticated, remote attacker with administrative privileges to write arbitrary files as root on the underlying operating system. This vulnerability is due to insufficient validation of the directory path during file synchronization. An attacker could exploit this vulnerability by crafting a directory path outside of the expected file location. A successful exploit could allow the attacker to create or replace any file on the underlying operating system.

A vulnerability in the Out-of-Band (OOB) Plug and Play (PnP) feature of Cisco Nexus Dashboard Fabric Controller (NDFC) could allow an unauthenticated, remote attacker to read arbitrary files. This vulnerability is due to an unauthenticated provisioning web server. An attacker could exploit this vulnerability through direct web requests to the provisioning server. A successful exploit could allow the attacker to read sensitive files in the PnP container that could facilitate further attacks on the PnP infrastructure.
