Fortinet FortiNAC keyUpload.jsp Arbitrary File Write
Posted on 15 March 2023
This Metasploit module uploads a payload to the /tmp directory in addition to a cron job to /etc/cron.d which executes the payload in the context of the root user. The core vulnerability is an arbitrary file write issue in /configWizard/keyUpload.jsp which is accessible remotely and without authentication. When you send the vulnerable endpoint a ZIP file, it will extract an attacker controlled file to a directory of the attackers choice on the target system. This issue is exploitable on FortiNAC versions 9.4 prior to 9.4.1, FortiNAC versions 9.2 prior to 9.2.6, FortiNAC versions 9.1 prior to 9.1.8, all versions of FortiNAC 8.8, all versions of FortiNAC 8.7, all versions of FortiNAC 8.6, all versions of FortiNAC 8.5, and all versions of FortiNAC 8.3.
