FAUCET Score

CVE-2019-3880 describes a medium-severity flaw in Samba's RPC endpoint for emulating the Windows registry service API, affecting versions prior to 4.8.11, 4.9.6, and 4.10.2, including distributions like Debian, Fedora, openSUSE, and Red Hat. An unprivileged attacker can exploit this vulnerability to create new registry hive files in arbitrary locations where they have Unix permissions, potentially leading to new file creation within Samba shares. With a CVSS score of 5.4, this vulnerability has a low attack complexity and requires low privileges, resulting in low impact on integrity and availability.
