1 CVE-2022-0336 276 Bypass 2022-08-29 2022-09-01
0.0
None ??? ??? ??? ??? ??? ???
The Samba AD DC includes checks when adding service principals names (SPNs) to an account to ensure that SPNs do not alias with those already in the database. Some of these checks are able to be bypassed if an account modification re-adds an SPN that was previously present on that account, such as one added when a computer is joined to a domain. An attacker who has the ability to write to an account can exploit this to perform a denial-of-service attack by adding an SPN that matches an existing service. Additionally, an attacker who can intercept traffic can impersonate existing services, resulting in a loss of confidentiality and integrity.
2 CVE-2021-23192 Bypass 2022-03-02 2022-08-29
5.0
None Remote Low Not required None Partial None
A flaw was found in the way samba implemented DCE/RPC. If a client to a Samba server sent a very large DCE/RPC request, and chose to fragment it, an attacker could replace later fragments with their own data, bypassing the signature requirements.

4 CVE-2018-5764 Bypass 2018-01-17 2021-12-16
5.0
None Remote Low Not required None Partial None
The parse_arguments function in options.c in rsyncd in rsync before 3.1.3 does not prevent multiple --protect-args uses, which allows remote attackers to bypass an argument-sanitization protection mechanism.
5 CVE-2017-17434 Bypass 2017-12-06 2019-10-03
7.5
None Remote Low Not required Partial Partial Partial
The daemon in rsync 3.1.2, and 3.1.3-development before 2017-12-03, does not check for fnamecmp filenames in the daemon_filter_list data structure (in the recv_files function in receiver.c) and also does not apply the sanitize_paths protection mechanism to pathnames found in "xname follows" strings (in the read_ndx_and_attrs function in rsync.c), which allows remote attackers to bypass intended access restrictions.
6 CVE-2017-17433 862 Bypass 2017-12-06 2019-10-03
4.3
None Remote Medium Not required None Partial None
The recv_files function in receiver.c in the daemon in rsync 3.1.2, and 3.1.3-development before 2017-12-03, proceeds with certain file metadata updates before checking for a filename in the daemon_filter_list data structure, which allows remote attackers to bypass intended access restrictions.
7 CVE-2017-15994 354 Bypass 2017-10-29 2019-10-03
7.5
None Remote Low Not required Partial Partial Partial
rsync 3.1.3-development before 2017-10-24 mishandles archaic checksums, which makes it easier for remote attackers to bypass intended access restrictions. NOTE: the rsync development branch has significant use beyond the rsync developers, e.g., the code has been copied for use in various GitHub projects.
8 CVE-2016-2119 94 Bypass 2016-07-07 2022-08-29
6.8
None Remote Medium Not required Partial Partial Partial
libcli/smb/smbXcli_base.c in Samba 4.x before 4.2.14, 4.3.x before 4.3.11, and 4.4.x before 4.4.5 allows man-in-the-middle attackers to bypass a client-signing protection mechanism, and consequently spoof SMB2 and SMB3 servers, via the (1) SMB2_SESSION_FLAG_IS_GUEST or (2) SMB2_SESSION_FLAG_IS_NULL flag.
9 CVE-2015-8467 269 Bypass 2015-12-29 2022-08-29
6.0
None Remote Medium ??? Partial Partial Partial
The samldb_check_user_account_control_acl function in dsdb/samdb/ldb_modules/samldb.c in Samba 4.x before 4.1.22, 4.2.x before 4.2.7, and 4.3.x before 4.3.3 does not properly check for administrative privileges during creation of machine accounts, which allows remote authenticated users to bypass intended access restrictions by leveraging the existence of a domain with both a Samba DC and a Windows DC, a similar issue to CVE-2015-2535.
10 CVE-2015-5252 264 Bypass 2015-12-29 2022-08-29
5.0
None Remote Low Not required None Partial None
vfs.c in smbd in Samba 3.x and 4.x before 4.1.22, 4.2.x before 4.2.7, and 4.3.x before 4.3.3, when share names with certain substring relationships exist, allows remote attackers to bypass intended file-access restrictions via a symlink that points outside of a share.
11 CVE-2013-6442 264 Bypass 2014-03-14 2017-01-07
5.8
None Remote Medium Not required Partial Partial None
The owner_set function in smbcacls.c in smbcacls in Samba 4.0.x before 4.0.16 and 4.1.x before 4.1.6 removes an ACL during use of a --chown or --chgrp option, which allows remote attackers to bypass intended access restrictions in opportunistic circumstances by leveraging an unintended administrative change.
12 CVE-2013-4475 264 Bypass 2013-11-13 2022-09-01
4.0
None Remote High Not required Partial Partial None
Samba 3.2.x through 3.6.x before 3.6.20, 4.0.x before 4.0.11, and 4.1.x before 4.1.1, when vfs_streams_depot or vfs_streams_xattr is enabled, allows remote attackers to bypass intended file restrictions by leveraging ACL differences between a file and an associated alternate data stream (ADS).
13 CVE-2013-0172 264 Bypass 2013-01-17 2013-01-18
3.5
None Remote Medium ??? None Partial None
Samba 4.0.x before 4.0.1, in certain Active Directory domain-controller configurations, does not properly interpret Access Control Entries that are based on an objectClass, which allows remote authenticated users to bypass intended restrictions on modifying LDAP directory objects by leveraging (1) objectClass access by a user, (2) objectClass access by a group, or (3) write access to an attribute.
14 CVE-2012-6150 20 Bypass 2013-12-03 2022-09-01
3.6
None Remote High ??? Partial Partial None
The winbind_name_list_to_sid_string_list function in nsswitch/pam_winbind.c in Samba through 4.1.2 handles invalid require_membership_of group names by accepting authentication by any user, which allows remote authenticated users to bypass intended access restrictions in opportunistic circumstances by leveraging an administrator's pam_winbind configuration-file mistake.
15 CVE-2010-0728 264 Bypass 2010-03-10 2010-03-10
8.5
None Remote Medium ??? Complete Complete Complete
smbd in Samba 3.3.11, 3.4.6, and 3.5.0, when libcap support is enabled, runs with the CAP_DAC_OVERRIDE capability, which allows remote authenticated users to bypass intended file permissions via standard filesystem operations with any client.
16 CVE-2004-0815 Bypass 2004-11-03 2018-10-30
7.5
None Remote Low Not required Partial Partial Partial
The unix_clean_name function in Samba 2.2.x through 2.2.11, and 3.0.x before 3.0.2a, trims certain directory names down to absolute paths, which could allow remote attackers to bypass the specified share restrictions and read, write, or list arbitrary files via "/.////" style sequences in pathnames.
