CVE-2019-6139

24
FAUCET Score

CVE-2019-6139 describes a critical remote arbitrary file upload vulnerability affecting Forcepoint User ID (FUID) server versions up to 1.2 on TCP port 5001. This flaw, with a CVSS score of 9.8, allows unauthenticated attackers to upload malicious files, potentially leading to remote code execution with high impact on confidentiality, integrity, and availability. While no public exploits (Metasploit, Nuclei, ExploitDB) or active exploitation have been observed, and community discussion is minimal, the vulnerability is easily exploitable over the network with low attack complexity. Organizations are advised to upgrade to FUID version 1.3 or higher, or implement firewall rules to restrict external access to TCP/5001.
