HIGH Summary
A flaw was found in the way samba before 4.7.9 and 4.8.4 allowed the use of weak NTLMv1 authentication even when NTLMv1 was explicitly disabled. A man-in-the-middle attacker could use this flaw to read the credential and other details passed between the samba server and client.

Common Weakness Enumeration (CWE)
Common Attack Pattern Enumeration and Classification (CAPEC)
- Session Sidejacking Session sidejacking takes advantage of an unencrypted communication channel between a victim and target system. The attacker sniffs traffic on a network looking for session tokens in unencrypted traffic. Once a session token is captured, the attacker performs malicious actions by using the stolen token with the targeted application to impersonate the victim. This attack is a specific method of session hijacking, which is exploiting a valid session token to gain unauthorized access to a target system or information. Other methods to perform a session hijacking are session fixation, cross-site scripting, or compromising a user or server machine and stealing the session token.
- Lifting credential(s)/key material embedded in client distributions (thick or thin) An attacker examines a target application's code or configuration files to find credential or key material that has been embedded within the application or its files. Many services require authentication with their users for the various purposes including billing, access control or attribution. Some client applications store the user's authentication credentials or keys to accelerate the login process. Some clients may have built-in keys or credentials (in which case the server is authenticating with the client, rather than the user). If the attacker is able to locate where this information is stored, they may be able to retrieve these credentials. The attacker could then use these stolen credentials to impersonate the user or client, respectively, in interactions with the service or use stolen keys to eavesdrop on nominally secure communications between the client and server.
- Password Recovery Exploitation An attacker may take advantage of the application feature to help users recover their forgotten passwords in order to gain access into the system with the same privileges as the original user. Generally password recovery schemes tend to be weak and insecure. Most of them use only one security question . For instance, mother's maiden name tends to be a fairly popular one. Unfortunately in many cases this information is not very hard to find, especially if the attacker knows the legitimate user. These generic security questions are also re-used across many applications, thus making them even more insecure. An attacker could for instance overhear a coworker talking to a bank representative at the work place and supplying their mother's maiden name for verification purposes. An attacker can then try to log in into one of the victim's accounts, click on "forgot password" and there is a good chance that the security question there will be to provide mother's maiden name. A weak password recovery scheme totally undermines the effectiveness of a strong password scheme.

Missing input sanitization checks on some of the input parameters to LDB database layer cause the LDAP server and DNS server to crash when following a NULL pointer. Samba releases 3.2.0 to 4.8.3 (inclusive) contain an error in libsmbclient that could allow a malicious server to overwrite client heap memory by returning an extra long filename in a directory listing. Missing database output checks on the returned directory attributes from the LDB database layer cause the DsCrackNames call in the DRSUAPI server to crash when following a NULL pointer. All versions of the Samba Active Directory LDAP server from 4.0.0 onwards are vulnerable to the disclosure of confidential attribute values, both of attributes where the schema SEARCH_FLAG_CONFIDENTIAL (0x80) searchFlags bit and where an explicit Access Control Entry has been specified on the ntSecurityDescriptor. last seen 2020-06-01 modified 2020-06-02 plugin id 111722 published 2018-08-15 reporter This script is Copyright (C) 2018 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/111722 title FreeBSD : samba -- multiple vulnerabilities (c4e9a427-9fc2-11e8-802a-000c29a1e3ec) NASL family Huawei Local Security Checks NASL id EULEROS_SA-2019-1598.NASL description According to the version of the samba packages installed, the EulerOS installation on the remote host is affected by the following vulnerability : - A flaw was found in the way samba allowed the use of weak NTLMv1 authentication even when NTLMv1 was explicitly disabled.
