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.

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.

According to the versions of the openldap packages installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :

  - A NULL pointer dereference was found in OpenLDAP server     and was fixed in openldap 2.4.55, during a request for     renaming RDNs. An unauthenticated attacker could     remotely crash the slapd process by sending a specially     crafted request, causing a Denial of     Service.(CVE-2020-25692)

  - 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-2020-15719)
