FAUCET Score

CVE-2017-15275 is a high-severity information disclosure vulnerability affecting Samba versions prior to 4.7.3, as well as canonical, debian, and redhat distributions. The flaw allows remote attackers to obtain sensitive information due to the server's failure to clear allocated heap memory. With a CVSS score of 7.5, this vulnerability is easily exploitable over the network with low complexity, potentially leading to a high impact on confidentiality.
