| CVE-2023-22392 | A Missing Release of Memory after Effective Lifetime vulnerability in the Packet Forwarding Engine (PFE) of Juniper Networks Junos OS allows an adjacent, unauthenticated attacker to cause a Denial of Service (DoS). PTX3000, PTX5000, QFX10000, PTX1000, PTX10002, and PTX10004, PTX10008 and PTX10016 with LC110x FPCs do not support certain flow-routes. Once a flow-route is received over an established BGP session and an attempt is made to install the resulting filter into the PFE, FPC heap memory is leaked. The FPC heap memory can be monitored using the CLI command "show chassis fpc". The following syslog messages can be observed if the respective filter derived from a flow-route cannot be installed. expr_dfw_sfm_range_add:661 SFM packet-length Unable to get a sfm entry for updating the hw expr_dfw_hw_sfm_add:750 Unable to add the filter secondarymatch to the hardware expr_dfw_base_hw_add:52 Failed to add h/w sfm data. expr_dfw_base_hw_create:114 Failed to add h/w data. expr_dfw_base_pfe_inst_create:241 Failed to create base inst for sfilter 0 on PFE 0 for __flowspec_default_inet__ expr_dfw_flt_inst_change:1368 Failed to create __flowspec_default_inet__ on PFE 0 expr_dfw_hw_pgm_fnum:465 dfw_pfe_inst_old not found for pfe_index 0! expr_dfw_bp_pgm_flt_num:548 Failed to pgm bind-point in hw: generic failure expr_dfw_bp_topo_handler:1102 Failed to program fnum. expr_dfw_entry_process_change:679 Failed to change instance for filter __flowspec_default_inet__. This issue affects Juniper Networks Junos OS: on PTX1000, PTX10002, and PTX10004, PTX10008 and PTX10016 with LC110x FPCs: * All versions prior to 20.4R3-S5; * 21.1 versions prior to 21.1R3-S4; * 21.2 versions prior to 21.2R3-S2; * 21.3 versions prior to 21.3R3; * 21.4 versions prior to 21.4R2-S2, 21.4R3; * 22.1 versions prior to 22.1R1-S2, 22.1R2. on PTX3000, PTX5000, QFX10000: * All versions prior to 20.4R3-S8; * 21.1 version 21.1R1 and later versions; * 21.2 versions prior to 21.2R3-S6; * 21.3 versions prior to 21.3R3-S5; * 21.4 versions prior to 21.4R3-S4; * 22.1 versions prior to 22.1R3-S3 * 22.2 versions prior to 22.2R3-S1 * 22.3 versions prior to 22.3R2-S2, 22.3R3 * 22.4 versions prior to 22.4R2. |
| CVE-2022-0918 | A vulnerability was discovered in the 389 Directory Server that allows an unauthenticated attacker with network access to the LDAP port to cause a denial of service. The denial of service is triggered by a single message sent over a TCP connection, no bind or other authentication is required. The message triggers a segmentation fault that results in slapd crashing. |
| CVE-2021-21484 | LDAP authentication in SAP HANA Database version 2.0 can be bypassed if the attached LDAP directory server is configured to enable unauthenticated bind. |
| CVE-2020-26214 | In Alerta before version 8.1.0, users may be able to bypass LDAP authentication if they provide an empty password when Alerta server is configure to use LDAP as the authorization provider. Only deployments where LDAP servers are configured to allow unauthenticated authentication mechanism for anonymous authorization are affected. A fix has been implemented in version 8.1.0 that returns HTTP 401 Unauthorized response for any authentication attempts where the password field is empty. As a workaround LDAP administrators can disallow unauthenticated bind requests by clients. |
| CVE-2018-11407 | An issue was discovered in the Ldap component in Symfony 2.8.x before 2.8.37, 3.3.x before 3.3.17, 3.4.x before 3.4.7, and 4.0.x before 4.0.7. It allows remote attackers to bypass authentication by logging in with a "null" password and valid username, which triggers an unauthenticated bind. NOTE: this issue exists because of an incomplete fix for CVE-2016-2403. |
| CVE-2017-2668 | 389-ds-base before versions 1.3.5.17 and 1.3.6.10 is vulnerable to an invalid pointer dereference in the way LDAP bind requests are handled. A remote unauthenticated attacker could use this flaw to make ns-slapd crash via a specially crafted LDAP bind request, resulting in denial of service. |
| CVE-2017-14623 | In the ldap.v2 (aka go-ldap) package through 2.5.0 for Go, an attacker may be able to login with an empty password. This issue affects an application using this package if these conditions are met: (1) it relies only on the return error of the Bind function call to determine whether a user is authorized (i.e., a nil return value is interpreted as successful authorization) and (2) it is used with an LDAP server allowing unauthenticated bind. |
| CVE-2016-2403 | Symfony before 2.8.6 and 3.x before 3.0.6 allows remote attackers to bypass authentication by logging in with an empty password and valid username, which triggers an unauthenticated bind. |
| CVE-2015-1772 | The LDAP implementation in HiveServer2 in Apache Hive before 1.0.1 and 1.1.x before 1.1.1, as used in IBM InfoSphere BigInsights 3.0, 3.0.0.1, and 3.0.0.2 and other products, mishandles simple unauthenticated and anonymous bind configurations, which allows remote attackers to bypass authentication via a crafted LDAP request. |
| CVE-2014-9043 | The user_ldap (aka LDAP user and group backend) application in ownCloud before 5.0.18, 6.x before 6.0.6, and 7.x before 7.0.3 allows remote attackers to bypass authentication via a null byte in the password and a valid user name, which triggers an unauthenticated bind. |
| CVE-2014-8763 | DokuWiki before 2014-05-05b, when using Active Directory for LDAP authentication, allows remote attackers to bypass authentication via a password starting with a null (\0) character and a valid user name, which triggers an unauthenticated bind. |
| CVE-2014-8088 | The (1) Zend_Ldap class in Zend before 1.12.9 and (2) Zend\Ldap component in Zend 2.x before 2.2.8 and 2.3.x before 2.3.3 allows remote attackers to bypass authentication via a password starting with a null byte, which triggers an unauthenticated bind. |
| CVE-2014-7807 | Apache CloudStack 4.3.x before 4.3.2 and 4.4.x before 4.4.2 allows remote attackers to bypass authentication via a login request without a password, which triggers an unauthenticated bind. |
| CVE-2014-6387 | gpc_api.php in MantisBT 1.2.17 and earlier allows remote attackers to bypass authenticated via a password starting will a null byte, which triggers an unauthenticated bind. |
| CVE-2014-4668 | The cherokee_validator_ldap_check function in validator_ldap.c in Cherokee 1.2.103 and earlier, when LDAP is used, does not properly consider unauthenticated-bind semantics, which allows remote attackers to bypass authentication via an empty password. |
| CVE-2014-3612 | The LDAPLoginModule implementation in the Java Authentication and Authorization Service (JAAS) in Apache ActiveMQ 5.x before 5.10.1 allows remote attackers to bypass authentication by logging in with an empty password and valid username, which triggers an unauthenticated bind. NOTE: this identifier has been SPLIT per ADT2 due to different vulnerability types. See CVE-2015-6524 for the use of wildcard operators in usernames. |
| CVE-2014-0074 | Apache Shiro 1.x before 1.2.3, when using an LDAP server with unauthenticated bind enabled, allows remote attackers to bypass authentication via an empty (1) username or (2) password. |
| CVE-2003-1434 | login_ldap 3.1 and 3.2 allows remote attackers to initiate unauthenticated bind requests if (1) bind_anon_dn is on, which allows a bind with no password provided, (2) bind_anon_cred is on, which allows a bind with no DN, or (3) bind_anon is on, which allows a bind with no DN or password. |
