CVE-2022-3592 2 Fedoraproject, Samba 2 Fedora, Samba 2023-09-17 N/A 6.5 MEDIUM
A symlink following vulnerability was found in Samba, where a user can create a symbolic link that will make 'smbd' escape the configured share path. This flaw allows a remote user with access to the exported part of the file system under a share via SMB1 unix extensions or NFS to create symlinks to files outside the 'smbd' configured share path and gain access to another restricted server's filesystem.
CVE-2022-38023 4 Fedoraproject, Microsoft, Netapp and 1 more 9 Fedora, Windows Server 2008, Windows Server 2012 and 6 more 2023-09-17 N/A 8.1 HIGH
Netlogon RPC Elevation of Privilege Vulnerability
CVE-2022-37967 4 Fedoraproject, Microsoft, Netapp and 1 more 9 Fedora, Windows Server 2008, Windows Server 2012 and 6 more 2023-09-17 N/A 7.2 HIGH
Windows Kerberos Elevation of Privilege Vulnerability
CVE-2022-37966 4 Fedoraproject, Microsoft, Netapp and 1 more 9 Fedora, Windows Server 2008, Windows Server 2012 and 6 more 2023-09-17 N/A 8.1 HIGH
Windows Kerberos RC4-HMAC Elevation of Privilege Vulnerability
CVE-2022-32746 1 Samba 1 Samba 2023-09-17 N/A 5.4 MEDIUM
A flaw was found in the Samba AD LDAP server. The AD DC database audit logging module can access LDAP message values freed by a preceding database module, resulting in a use-after-free issue. This issue is only possible when modifying certain privileged attributes, such as userAccountControl.
CVE-2022-32744 1 Samba 1 Samba 2023-09-17 N/A 8.8 HIGH
A flaw was found in Samba. The KDC accepts kpasswd requests encrypted with any key known to it. By encrypting forged kpasswd requests with its own key, a user can change other users' passwords, enabling full domain takeover.
CVE-2022-2031 1 Samba 1 Samba 2023-09-17 N/A 8.8 HIGH
A flaw was found in Samba. The security vulnerability occurs when KDC and the kpasswd service share a single account and set of keys, allowing them to decrypt each other's tickets. A user who has been requested to change their password, can exploit this flaw to obtain and use tickets to other services.
CVE-2022-0336 2 Fedoraproject, Samba 2 Fedora, Samba 2023-09-17 N/A 8.8 HIGH
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.
CVE-2021-44141 3 Fedoraproject, Redhat, Samba 3 Fedora, Storage, Samba 2023-09-17 3.5 LOW 4.3 MEDIUM
All versions of Samba prior to 4.15.5 are vulnerable to a malicious client using a server symlink to determine if a file or directory exists in an area of the server file system not exported under the share definition. SMB1 with unix extensions has to be enabled in order for this attack to succeed.
CVE-2021-3738 1 Samba 1 Samba 2023-09-17 6.5 MEDIUM 8.8 HIGH
In DCE/RPC it is possible to share the handles (cookies for resource state) between multiple connections via a mechanism called 'association groups'. These handles can reference connections to our sam.ldb database. However while the database was correctly shared, the user credentials state was only pointed at, and when one connection within that association group ended, the database would be left pointing at an invalid 'struct session_info'. The most likely outcome here is a crash, but it is possible that the use-after-free could instead allow different user state to be pointed at and this might allow more privileged access.
CVE-2021-3670 3 Fedoraproject, Redhat, Samba 3 Fedora, Storage, Samba 2023-09-17 N/A 6.5 MEDIUM
MaxQueryDuration not honoured in Samba AD DC LDAP
CVE-2021-23192 1 Samba 1 Samba 2023-09-17 5.0 MEDIUM 7.5 HIGH
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.
CVE-2021-20316 3 Debian, Redhat, Samba 7 Debian Linux, Enterprise Linux, Enterprise Linux Aus and 4 more 2023-09-17 N/A 6.8 MEDIUM
A flaw was found in the way Samba handled file/directory metadata. This flaw allows an authenticated attacker with permissions to read or modify share metadata, to perform this operation outside of the share.
CVE-2021-20251 2 Fedoraproject, Samba 2 Fedora, Samba 2023-09-17 N/A 5.9 MEDIUM
A flaw was found in samba. A race condition in the password lockout code may lead to the risk of brute force attacks being successful if special conditions are met.
CVE-2020-25722 4 Canonical, Debian, Fedoraproject and 1 more 4 Ubuntu Linux, Debian Linux, Fedora and 1 more 2023-09-17 6.5 MEDIUM 8.8 HIGH
Multiple flaws were found in the way samba AD DC implemented access and conformance checking of stored data. An attacker could use this flaw to cause total domain compromise.
CVE-2020-25721 1 Samba 1 Samba 2023-09-17 6.5 MEDIUM 8.8 HIGH
Kerberos acceptors need easy access to stable AD identifiers (eg objectSid). Samba as an AD DC now provides a way for Linux applications to obtain a reliable SID (and samAccountName) in issued tickets.
CVE-2020-25719 5 Canonical, Debian, Fedoraproject and 2 more 17 Ubuntu Linux, Debian Linux, Fedora and 14 more 2023-09-17 9.0 HIGH 7.2 HIGH
A flaw was found in the way Samba, as an Active Directory Domain Controller, implemented Kerberos name-based authentication. The Samba AD DC, could become confused about the user a ticket represents if it did not strictly require a Kerberos PAC and always use the SIDs found within. The result could include total domain compromise.
CVE-2020-25718 2 Fedoraproject, Samba 2 Fedora, Samba 2023-09-17 6.5 MEDIUM 8.8 HIGH
A flaw was found in the way samba, as an Active Directory Domain Controller, is able to support an RODC (read-only domain controller). This would allow an RODC to print administrator tickets.
CVE-2020-25717 5 Canonical, Debian, Fedoraproject and 2 more 25 Ubuntu Linux, Debian Linux, Fedora and 22 more 2023-09-17 8.5 HIGH 8.1 HIGH
A flaw was found in the way Samba maps domain users to local users. An authenticated attacker could use this flaw to cause possible privilege escalation.
CVE-2016-2124 5 Canonical, Debian, Fedoraproject and 2 more 24 Ubuntu Linux, Debian Linux, Fedora and 21 more 2023-09-17 4.3 MEDIUM 5.9 MEDIUM
A flaw was found in the way samba implemented SMB1 authentication. An attacker could use this flaw to retrieve the plaintext password sent over the wire even if Kerberos authentication was required.
