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.

The remote Redhat Enterprise Linux 7 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - openldap: ACL restrictions bypass due to sasl_ssf value being set permanently (CVE-2019-13565)

  - /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-2016-4984)

  - 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-2019-13057)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

This plugin has been deprecated as it does not adhere to established standards for this style of check.

The version of openldap installed on the remote host is prior to 2.4.40-16.36. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS-2023-1741 advisory.

  - 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-2021-27212)

The remote host is running a version of macOS / Mac OS X that is 10.13.x prior to 10.13.6 Security Update 2019-007, 10.14.x prior to 10.14.6 Security Update 2019-002, or 10.15.x prior to 10.15.2. It is, therefore, affected by multiple vulnerabilities :

  - 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-2012-1164)

  - 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-2012-2668)

  - 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-2013-4449)

  - 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-2015-1545)

  - tcpdump before 4.9.3 has a heap-based buffer over-read     related to aoe_print in print-aoe.c and lookup_emem in     addrtoname.c. (CVE-2017-16808)

  - The SMB parser in tcpdump before 4.9.3 has buffer over-     reads in print-smb.c:print_trans() for \MAILSLOT\BROWSE     and \PIPE\LANMAN. (CVE-2018-16451)

  - The SMB parser in tcpdump before 4.9.3 has stack     exhaustion in smbutil.c:smb_fdata() via recursion.

    This may open up an attack vector involving extra data     at the end of a request. (CVE-2019-15161)

  - rpcapd/daemon.c in libpcap before 1.9.1 on non-Windows     platforms provides details about why authentication     failed, which might make it easier for attackers to     enumerate valid usernames. (CVE-2019-15162)

This update for openldap2 fixes the following issues :

Security issues fixed :

CVE-2019-13565: Fixed ssf memory reuse that leads to incorrect authorization of another connection, granting excess connection rights (ssf) (bsc#1143194).

CVE-2019-13057: Fixed rootDN of a backend that may proxyauth incorrectly to another backend, violating multi-tenant isolation (bsc#1143273).

Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Several security vulnerabilities were discovered in openldap, a server and tools to provide a standalone directory service.

CVE-2019-13057

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-2019-13565

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.

For Debian 8 'Jessie', these problems have been fixed in version 2.4.40+dfsg-1+deb8u5.

We recommend that you upgrade your openldap packages.

The remote Ubuntu 16.04 LTS / 18.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-4078-1 advisory.

    It was discovered that OpenLDAP incorrectly handled rootDN delegation. A database administrator could use     this issue to request authorization as an identity from another database, contrary to expectations.
    (CVE-2019-13057)

    It was discovered that OpenLDAP incorrectly handled SASL authentication and session encryption. After a     first SASL bind was completed, it was possible to obtain access by performing simple binds, contrary to     expectations. (CVE-2019-13565)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
