CVE Severity Published▾ Status Exploitation Description
CVE-2022-29155 Critical 2022-05-04 Not applicable Forecast only In OpenLDAP 2.x before 2.5.12 and 2.6.x before 2.6.2, a SQL injection vulnerability exists in the experimental back-sql backend to slapd, via a SQL statement within an LDAP query. This can occur during an LDAP search operation when the search filter is processed, due to a lack of proper escaping.
CVE-2020-25709 High 2021-05-18 Not applicable No public exploit A flaw was found in OpenLDAP. This flaw allows an attacker who can send a malicious packet to be processed by OpenLDAP’s slapd server, to trigger an assertion failure. The highest threat from this vulnerability is to system availability.
CVE-2021-27212 High 2021-02-14 Not applicable Forecast only In OpenLDAP through 2.4.57 and 2.5.x through 2.5.1alpha, an assertion failure in slapd can occur in the issuerAndThisUpdateCheck function via a crafted packet, resulting in a denial of service (daemon exit) via a short timestamp. This is related to schema_init.c and checkTime.
CVE-2020-36230 High 2021-01-26 Not applicable No public exploit A flaw was discovered in OpenLDAP before 2.4.57 leading in an assertion failure in slapd in the X.509 DN parsing in decode.c ber_next_element, resulting in denial of service.
CVE-2020-36229 High 2021-01-26 Not applicable No public exploit A flaw was discovered in ldap_X509dn2bv in OpenLDAP before 2.4.57 leading to a slapd crash in the X.509 DN parsing in ad_keystring, resulting in denial of service.
CVE-2020-36228 High 2021-01-26 Not applicable Forecast only An integer underflow was discovered in OpenLDAP before 2.4.57 leading to a slapd crash in the Certificate List Exact Assertion processing, resulting in denial of service.
CVE-2020-36227 High 2021-01-26 Not applicable Forecast only A flaw was discovered in OpenLDAP before 2.4.57 leading to an infinite loop in slapd with the cancel_extop Cancel operation, resulting in denial of service.
CVE-2020-36226 High 2021-01-26 Not applicable No public exploit A flaw was discovered in OpenLDAP before 2.4.57 leading to a memch->bv_len miscalculation and slapd crash in the saslAuthzTo processing, resulting in denial of service.
CVE-2020-36225 High 2021-01-26 Not applicable No public exploit A flaw was discovered in OpenLDAP before 2.4.57 leading to a double free and slapd crash in the saslAuthzTo processing, resulting in denial of service.
CVE-2020-36224 High 2021-01-26 Not applicable No public exploit A flaw was discovered in OpenLDAP before 2.4.57 leading to an invalid pointer free and slapd crash in the saslAuthzTo processing, resulting in denial of service.
CVE-2020-36223 High 2021-01-26 Not applicable No public exploit A flaw was discovered in OpenLDAP before 2.4.57 leading to a slapd crash in the Values Return Filter control handling, resulting in denial of service (double free and out-of-bounds read).
CVE-2020-36222 High 2021-01-26 Not applicable Forecast only A flaw was discovered in OpenLDAP before 2.4.57 leading to an assertion failure in slapd in the saslAuthzTo validation, resulting in denial of service.
CVE-2020-36221 High 2021-01-26 Not applicable Forecast only An integer underflow was discovered in OpenLDAP before 2.4.57 leading to slapd crashes in the Certificate Exact Assertion processing, resulting in denial of service (schema_init.c serialNumberAndIssuerCheck).
CVE-2020-15719 Medium 2020-07-14 Not applicable No public exploit libldap in certain third-party OpenLDAP packages has a certificate-validation flaw when the third-party package is asserting RFC6125 support. It considers CN even when there is a non-matching subjectAltName (SAN). This is fixed in, for example, openldap-2.4.46-10.el8 in Red Hat Enterprise Linux.
CVE-2014-8182 High 2020-01-02 Not applicable No public exploit An off-by-one error leading to a crash was discovered in openldap 2.4 when processing DNS SRV messages. If slapd was configured to use the dnssrv backend, an attacker could crash the service with crafted DNS responses.
CVE-2019-13565 High 2019-07-26 Not applicable No public exploit An issue was discovered in OpenLDAP 2.x before 2.4.48. When using SASL authentication and session encryption, and relying on the SASL security layers in slapd access controls, it is possible to obtain access that would otherwise be denied via a simple bind for any identity covered in those ACLs. After the first SASL bind is completed, the sasl_ssf value is retained for all new non-SASL connections. Depending on the ACL configuration, this can affect different types of operations (searches, modifications, etc.). In other words, a successful authorization step completed by one user affects the authorization requirement for a different user.
CVE-2019-13057 Medium 2019-07-26 Not applicable No public exploit An issue was discovered in the server in OpenLDAP before 2.4.48. When the server administrator delegates rootDN (database admin) privileges for certain databases but wants to maintain isolation (e.g., for multi-tenant deployments), slapd does not properly stop a rootDN from requesting authorization as an identity from another database during a SASL bind or with a proxyAuthz (RFC 4370) control. (It is not a common configuration to deploy a system where the server administrator and a DB administrator enjoy different levels of trust.)
CVE-2017-17740 High 2017-12-18 Not applicable No public exploit contrib/slapd-modules/nops/nops.c in OpenLDAP through 2.4.45, when both the nops module and the memberof overlay are enabled, attempts to free a buffer that was allocated on the stack, which allows remote attackers to cause a denial of service (slapd crash) via a member MODDN operation.
CVE-2017-14159 Medium 2017-09-05 Not applicable No public exploit slapd in OpenLDAP 2.4.45 and earlier creates a PID file after dropping privileges to a non-root account, which might allow local users to kill arbitrary processes by leveraging access to this non-root account for PID file modification before a root script executes a "kill `cat /pathname`" command, as demonstrated by openldap-initscript.
CVE-2016-4984 Medium 2017-07-17 Not applicable No public exploit /usr/libexec/openldap/generate-server-cert.sh in openldap-servers sets weak permissions for the TLS certificate, which allows local users to obtain the TLS certificate by leveraging a race condition between the creation of the certificate, and the chmod to protect it.
CVE-2015-3276 High 2015-12-07 Not applicable No public exploit The nss_parse_ciphers function in libraries/libldap/tls_m.c in OpenLDAP does not properly parse OpenSSL-style multi-keyword mode cipher strings, which might cause a weaker than intended cipher to be used and allow remote attackers to have unspecified impact via unknown vectors.
CVE-2015-6908 Medium 2015-09-11 Not applicable Working exploit published The ber_get_next function in libraries/liblber/io.c in OpenLDAP 2.4.42 and earlier allows remote attackers to cause a denial of service (reachable assertion and application crash) via crafted BER data, as demonstrated by an attack against slapd.
CVE-2014-9713 Medium 2015-04-01 Not applicable No public exploit The default slapd configuration in the Debian openldap package 2.4.23-3 through 2.4.39-1.1 allows remote authenticated users to modify the user's permissions and other user attributes via unspecified vectors.
CVE-2015-1546 Medium 2015-02-12 Not applicable No public exploit Double free vulnerability in the get_vrFilter function in servers/slapd/filter.c in OpenLDAP 2.4.40 allows remote attackers to cause a denial of service (crash) via a crafted search query with a matched values control.
CVE-2015-1545 Medium 2015-02-12 Not applicable No public exploit The deref_parseCtrl function in servers/slapd/overlays/deref.c in OpenLDAP 2.4.13 through 2.4.40 allows remote attackers to cause a denial of service (NULL pointer dereference and crash) via an empty attribute list in a deref control in a search request.
CVE-2013-4449 Medium 2014-02-05 Not applicable No public exploit The rwm overlay in OpenLDAP 2.4.23, 2.4.36, and earlier does not properly count references, which allows remote attackers to cause a denial of service (slapd crash) by unbinding immediately after a search request, which triggers rwm_conn_destroy to free the session context while it is being used by rwm_op_search.
CVE-2012-1164 Low 2012-06-29 Not applicable No public exploit slapd in OpenLDAP before 2.4.30 allows remote attackers to cause a denial of service (assertion failure and daemon exit) via an LDAP search query with attrsOnly set to true, which causes empty attributes to be returned.
CVE-2012-2668 Medium 2012-06-17 Not applicable No public exploit libraries/libldap/tls_m.c in OpenLDAP, possibly 2.4.31 and earlier, when using the Mozilla NSS backend, always uses the default cipher suite even when TLSCipherSuite is set, which might cause OpenLDAP to use weaker ciphers than intended and make it easier for remote attackers to obtain sensitive information.
CVE-2011-4079 Medium 2011-10-27 Not applicable No public exploit Off-by-one error in the UTF8StringNormalize function in OpenLDAP 2.4.26 and earlier allows remote attackers to cause a denial of service (slapd crash) via a zero-length string that triggers a heap-based buffer overflow, as demonstrated using an empty postalAddressAttribute value in an LDIF entry.
CVE-2011-1081 Medium 2011-03-20 Not applicable Working exploit published modrdn.c in slapd in OpenLDAP 2.4.x before 2.4.24 allows remote attackers to cause a denial of service (daemon crash) via a relative Distinguished Name (DN) modification request (aka MODRDN operation) that contains an empty value for the OldDN field.
CVE-2011-1025 Medium 2011-03-20 Not applicable No public exploit bind.cpp in back-ndb in OpenLDAP 2.4.x before 2.4.24 does not require authentication for the root Distinguished Name (DN), which allows remote attackers to bypass intended access restrictions via an arbitrary password.
CVE-2011-1024 Medium 2011-03-20 Not applicable No public exploit chain.c in back-ldap in OpenLDAP 2.4.x before 2.4.24, when a master-slave configuration with a chain overlay and ppolicy_forward_updates (aka authentication-failure forwarding) is used, allows remote authenticated users to bypass external-program authentication by sending an invalid password to a slave server.
CVE-2010-0212 Medium 2010-07-28 Not applicable No public exploit OpenLDAP 2.4.22 allows remote attackers to cause a denial of service (crash) via a modrdn call with a zero-length RDN destination string, which is not properly handled by the smr_normalize function and triggers a NULL pointer dereference in the IA5StringNormalize function in schema_init.c, as demonstrated using the Codenomicon LDAPv3 test suite.
CVE-2010-0211 Critical 2010-07-28 Not applicable Working exploit published The slap_modrdn2mods function in modrdn.c in OpenLDAP 2.4.22 does not check the return value of a call to the smr_normalize function, which allows remote attackers to cause a denial of service (segmentation fault) and possibly execute arbitrary code via a modrdn call with an RDN string containing invalid UTF-8 sequences, which triggers a free of an invalid, uninitialized pointer in the slap_mods_free function, as demonstrated using the Codenomicon LDAPv3 test suite.
CVE-2009-3767 Medium 2009-10-23 Not applicable No public exploit libraries/libldap/tls_o.c in OpenLDAP 2.2 and 2.4, and possibly other versions, when OpenSSL is used, does not properly handle a '\0' character in a domain name in the subject's Common Name (CN) field of an X.509 certificate, which allows man-in-the-middle attackers to spoof arbitrary SSL servers via a crafted certificate issued by a legitimate Certification Authority, a related issue to CVE-2009-2408.
CVE-2008-2952 Medium 2008-07-01 Not applicable Working exploit published liblber/io.c in OpenLDAP 2.2.4 to 2.4.10 allows remote attackers to cause a denial of service (program termination) via crafted ASN.1 BER datagrams that trigger an assertion error.
CVE-2008-0658 Medium 2008-02-13 Not applicable No public exploit slapd/back-bdb/modrdn.c in the BDB backend for slapd in OpenLDAP 2.3.39 allows remote authenticated users to cause a denial of service (daemon crash) via a modrdn operation with a NOOP (LDAP_X_NO_OPERATION) control, a related issue to CVE-2007-6698.
CVE-2007-6698 Medium 2008-02-01 Not applicable No public exploit The BDB backend for slapd in OpenLDAP before 2.3.36 allows remote authenticated users to cause a denial of service (crash) via a potentially-successful modify operation with the NOOP control set to critical, possibly due to a double free vulnerability.
CVE-2007-5708 High 2007-10-30 Not applicable No public exploit slapo-pcache (overlays/pcache.c) in slapd in OpenLDAP before 2.3.39, when running as a proxy-caching server, allocates memory using a malloc variant instead of calloc, which prevents an array from being initialized properly and might allow attackers to cause a denial of service (segmentation fault) via unknown vectors that prevent the array from being null terminated.
CVE-2007-5707 High 2007-10-30 Not applicable No public exploit OpenLDAP before 2.3.39 allows remote attackers to cause a denial of service (slapd crash) via an LDAP request with a malformed objectClasses attribute. NOTE: this has been reported as a double free, but the reports are inconsistent.
CVE-2006-6493 Medium 2006-12-13 Not applicable Working exploit published Buffer overflow in the krbv4_ldap_auth function in servers/slapd/kerberos.c in OpenLDAP 2.4.3 and earlier, when OpenLDAP is compiled with the --enable-kbind (Kerberos KBIND) option, allows remote attackers to execute arbitrary code via an LDAP bind request using the LDAP_AUTH_KRBV41 authentication method and long credential data.
CVE-2006-5779 High 2006-11-07 Not applicable Forecast only OpenLDAP before 2.3.29 allows remote attackers to cause a denial of service (daemon crash) via LDAP BIND requests with long authcid names, which triggers an assertion failure.
CVE-2006-4600 Low 2006-09-07 Not applicable No public exploit slapd in OpenLDAP before 2.3.25 allows remote authenticated users with selfwrite Access Control List (ACL) privileges to modify arbitrary Distinguished Names (DN).
CVE-2006-2754 Medium 2006-06-01 Not applicable No public exploit Stack-based buffer overflow in st.c in slurpd for OpenLDAP before 2.3.22 might allow attackers to execute arbitrary code via a long hostname.
