2) Improper Authorization

EUVDB-ID: #VU81875

Risk: High

CVSSv4.0: 8 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N/E:U/U:Amber]

CVE-ID: CVE-2023-3961

CWE-ID: CWE-285 - Improper Authorization

Exploit availability: No

The vulnerability allows a remote attacker to compromise the affected system.

The vulnerability exists due to improper input validation when handling client pipe names. A remote attacker can provide a specially crafted pipe name containing directory traversal characters and force Samba to connect to Unix domain sockets outside of the private directory meant to restrict the services a client could connect to.The connection to Unix domain sockets is performed as root, which means that if client sends a pipe name that resolved to an external service using an existing Unix domain socket, the client is able to connect to it without any filesystem restrictions.
