Samba users have reported that the exploit for "ZeroLogin" passes against Samba. I'd propose we should do releases (for 4.10, 4.11 and 4.12) as soon as possible (if possible tomorrow before 12:00 UTC). 4.13 can follow a bit later (there we may remove the global "server schannel" option).

It is, therefore, affected by a remote DoS and a remote password manipulation vulnerability.

First we will own root using SAMBA exploit manually and later with Metasploit. We’ll also use Distcc exploit which unlike samba exploit gives us user shell and thus further we will use various privilege escalation methods like nmap SUID binary, Weak SSH A vulnerable/poorly configured SMB machine (remote or local) SMB PORT: 445.

(BZ#1776952) Security Fix(es): * samba: smb client vulnerable to filenames containing path separators (CVE-2019-10218) * samba: Crash after failed character conversion at log level 3 or above (CVE Samba 4.11 will need to ship with this fixed Samba 4.7 -> 4.10 use the forking LDAP server, making this a self-DoS for the default configuration (but an issue if -M single or -M prefork were specified). Previous investigations did not find other projects that allow untrusted input into LDB DN functions. A flaw was found in the samba client, all samba versions before samba 4.11.2, 4.10.10 and 4.9.15, where a malicious server can supply a pathname to the client with separators. This could allow the client to access files and folders outside of the SMB network pathnames. New summary : Samba since version 3.5.0 and before 4.6.4, 4.5.10 and 4.4.14 is vulnerable to remote code execution vulnerability, allowing a malicious client to upload a shared library to a writable share, and then cause the server to load and execute it. Because Samba has implemented the MS-NRPC protocol as it has been designed by Microsoft, Samba domain controllers are also affected by this vulnerability.
