A heap-buffer overflow was found in the way samba clients processed extra long filename in a directory listing. A malicious samba server could use this flaw to cause arbitrary code execution on a samba client. Samba versions before 4.6.16, 4.7.9 and 4.8.4 are vulnerable.
The (1) CreateAccount, (2) OpenAccount, (3) AddAccountRights, and (4) RemoveAccountRights LSA RPC procedures in smbd in Samba 3.4.x before 3.4.17, 3.5.x before 3.5.15, and 3.6.x before 3.6.5 do not properly restrict modifications to the privileges database, which allows remote authenticated users to obtain the "take ownership" privilege via an LSA connection.
The Samba vfs_fruit module uses extended file attributes (EA, xattr) to provide "...enhanced compatibility with Apple SMB clients and interoperability with a Netatalk 3 AFP fileserver." Samba versions prior to 4.13.17, 4.14.12 and 4.15.5 with vfs_fruit configured allow out-of-bounds heap read and write via specially crafted extended file attributes. A remote attacker with write access to extended file attributes can execute arbitrary code with the privileges of smbd, typically root.
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.
A flaw was found in samba versions 4.0.0 to 4.5.2. The Samba routine ndr_pull_dnsp_name contains an integer wrap problem, leading to an attacker-controlled memory overwrite. ndr_pull_dnsp_name parses data from the Samba Active Directory ldb database. Any user who can write to the dnsRecord attribute over LDAP can trigger this memory corruption. By default, all authenticated LDAP users can write to the dnsRecord attribute on new DNS objects. This makes the defect a remote privilege escalation.
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.
On a Samba 4 AD DC the LDAP server in all versions of Samba from 4.0.0 onwards incorrectly validates permissions to modify passwords over LDAP allowing authenticated users to change any other users' passwords, including administrative users and privileged service accounts (eg Domain Controllers).
PAC parsing in MIT Kerberos 5 (aka krb5) before 1.19.4 and 1.20.x before 1.20.1 has integer overflows that may lead to remote code execution (in KDC, kadmind, or a GSS or Kerberos application server) on 32-bit platforms (which have a resultant heap-based buffer overflow), and cause a denial of service on other platforms. This occurs in krb5_pac_parse in lib/krb5/krb/pac.c. Heimdal before 7.7.1 has "a similar bug."
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.
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.
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.
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.
The Samba Web Administration Tool (SWAT) in Samba 3.x before 3.5.21, 3.6.x before 3.6.12, and 4.x before 4.0.2 allows remote attackers to conduct clickjacking attacks via a (1) FRAME or (2) IFRAME element.
smbfs in Samba 3.5.8 and earlier attempts to use (1) mount.cifs to append to the /etc/mtab file and (2) umount.cifs to append to the /etc/mtab.tmp file without first checking whether resource limits would interfere, which allows local users to trigger corruption of the /etc/mtab file via a process with a small RLIMIT_FSIZE value, a related issue to CVE-2011-1089.
client/mount.cifs.c in mount.cifs in smbfs in Samba 3.4.5 and earlier does not verify that the (1) device name and (2) mountpoint strings are composed of valid characters, which allows local users to cause a denial of service (mtab corruption) via a crafted string.
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.
The internal DNS server in Samba 4.x before 4.0.18 does not check the QR field in the header section of an incoming DNS message before sending a response, which allows remote attackers to cause a denial of service (CPU and bandwidth consumption) via a forged response packet that triggers a communication loop, a related issue to CVE-1999-0103.
Samba 3.2.0 through 3.2.6, when registry shares are enabled, allows remote authenticated users to access the root filesystem via a crafted connection request that specifies a blank share name.
It was found that Samba before versions 4.5.3, 4.4.8, 4.3.13 always requested forwardable tickets when using Kerberos authentication. A service to which Samba authenticated using Kerberos could subsequently use the ticket to impersonate Samba to other services or domain users.
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.
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 supports connections that are encrypted but unsigned, which allows man-in-the-middle attackers to conduct encrypted-to-unencrypted downgrade attacks by modifying the client-server data stream, related to clidfs.c, libsmb_server.c, and smbXcli_base.c.
An issue was discovered in rsync before 3.2.5 that allows malicious remote servers to write arbitrary files inside the directories of connecting peers. The server chooses which files/directories are sent to the client. However, the rsync client performs insufficient validation of file names. A malicious rsync server (or Man-in-The-Middle attacker) can overwrite arbitrary files in the rsync client target directory and subdirectories (for example, overwrite the .ssh/authorized_keys file).
The check_secret function in authenticate.c in rsync 3.1.0 and earlier allows remote attackers to cause a denial of service (infinite loop and CPU consumption) via a user name which does not exist in the secrets file.
The sys_recvfrom function in nmbd in Samba 3.6.x before 3.6.24, 4.0.x before 4.0.19, and 4.1.x before 4.1.9 allows remote attackers to cause a denial of service (infinite loop and CPU consumption) via a malformed UDP packet.
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.
A missing input sanitization flaw was found in the implementation of LDP database used for the LDAP server. An attacker could use this flaw to cause a denial of service against a samba server, used as a Active Directory Domain Controller. All versions of Samba from 4.8.0 onwards are vulnerable
The check_mtab function in client/mount.cifs.c in mount.cifs in smbfs in Samba 3.5.10 and earlier does not properly verify that the (1) device name and (2) mountpoint strings are composed of valid characters, which allows local users to cause a denial of service (mtab corruption) via a crafted string. NOTE: this vulnerability exists because of an incorrect fix for CVE-2010-0547.
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.
The EMC RSA Identity Governance and Lifecycle, RSA Via Lifecycle and Governance and RSA IMG products (RSA Identity Governance and Lifecycle versions 7.0.1, 7.0.2, all patch levels; RSA Via Lifecycle and Governance version 7.0, all patch levels; RSA Identity Management and Governance (RSA IMG) versions 6.9.1, all patch levels) allow an application administrator to upload arbitrary files that may potentially contain a malicious code. The malicious file could be then executed on the affected system with the privileges of the user the application is running under.
The dashboard subscription interface in Request Tracker (RT) 4.x before 4.0.25, 4.2.x before 4.2.14, and 4.4.x before 4.4.2 might allow remote authenticated users with certain privileges to execute arbitrary code via a crafted saved search name.
An issue was discovered in FusionPBX before 4.5.30. The fax_post_size may have risky characters (it is not constrained to preset values).
GaussDB 200 with version of 6.5.1 have a command injection vulnerability. Due to insufficient input validation, remote attackers with low permissions could exploit this vulnerability by sending crafted commands to the affected device. Successful exploit could allow an attacker to execute commands.
cPanel before 62.0.17 allows demo accounts to execute code via an NVData_fetchinc API call (SEC-233).
In cPanel before 62.0.4, Exim piped filters ran in the context of an incorrect user account when delivering to a system user (SEC-204).
The Key Management feature in the SecureSphere Operations Manager (SOM) Management Server in Imperva SecureSphere 9.0.0.5 allows remote authenticated users to upload executable files via the (1) private_key or (2) public_key parameter in a T/keyManagement request to plain/settings.html, as demonstrated by uploading a Linux ELF file and a shell script.
The (1) file upload component and (2) File Abstraction Layer (FAL) in TYPO3 6.0.x before 6.0.8 and 6.1.x before 6.1.3 do not properly check file extensions, which allow remote authenticated editors to execute arbitrary PHP code by uploading a .php file.
plain/actionsets.html in the SecureSphere Operations Manager (SOM) Management Server in Imperva SecureSphere 9.0.0.5 allows remote authenticated users to execute arbitrary commands via a task with a [command].value field in conjunction with an [arguments].value field.
cPanel before 64.0.21 allows demo accounts to execute code via an ImageManager_dimensions API call (SEC-243).
Improper input validation vulnerability in SYNOPHOTO_Flickr_MultiUpload in Synology Photo Station before 6.8.3-3463 and before 6.3-2971 allows remote authenticated users to execute arbitrary codes via the prog_id parameter.
The Cacti component in GroundWork Monitor Enterprise 6.7.0 does not properly perform authorization checks, which allows remote authenticated users to read or modify configuration settings via unspecified vectors, as demonstrated by reading credentials.
OpenText Documentum Content Server (formerly EMC Documentum Content Server) through 7.3 does not properly validate the input of the PUT_FILE RPC-command, which allows any authenticated user to hijack an arbitrary file from the Content Server filesystem; because some files on the Content Server filesystem are security-sensitive, this leads to privilege escalation.
The users controller in Katello 1.5.0-14 and earlier, and Red Hat Satellite, does not check authorization for the update_roles action, which allows remote authenticated users to gain privileges by setting a user account to an administrator account.
Windows Routing and Remote Access Service (RRAS) Remote Code Execution Vulnerability
core/get_menudiv.php in Dolibarr before 11.0.4 allows remote authenticated attackers to bypass intended access restrictions via a non-alphanumeric menu parameter.
IBM Maximo Asset Management 7.1, 7.5, and 7.6 could allow a remote attacker to hijack a user's session, caused by the failure to invalidate an existing session identifier. An attacker could exploit this vulnerability to gain access to another user's session. IBM X-Force ID: 120253.
MySQL before 5.0.25 and 5.1 before 5.1.12 evaluates arguments of suid routines in the security context of the routine's definer instead of the routine's caller, which allows remote authenticated users to gain privileges through a routine that has been made available using GRANT EXECUTE.
Windows Routing and Remote Access Service (RRAS) Remote Code Execution Vulnerability
Windows Remote Desktop Licensing Service Spoofing Vulnerability
REDCap before 4.14.0 allows remote authenticated users to execute arbitrary commands via shell metacharacters in the logic of a custom rule.
