389-ds-base before versions 1.3.8.5, 1.4.0.12 is vulnerable to a Cleartext Storage of Sensitive Information. By default, when the Replica and/or retroChangeLog plugins are enabled, 389-ds-base stores passwords in plaintext format in their respective changelog files. An attacker with sufficiently high privileges, such as root or Directory Manager, can query these files in order to retrieve plaintext passwords.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - 389-ds-base before versions 1.3.8.5, 1.4.0.12 is vulnerable to a Cleartext Storage of Sensitive     Information. By default, when the Replica and/or retroChangeLog plugins are enabled, 389-ds-base stores     passwords in plaintext format in their respective changelog files. An attacker with sufficiently high     privileges, such as root or Directory Manager, can query these files in order to retrieve plaintext     passwords. (CVE-2018-10871)

Note that Nessus relies on the presence of the package as reported by the vendor.

The remote Oracle Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2019-3401 advisory.

  - In 389-ds-base up to version 1.4.1.2, requests are handled by workers threads. Each sockets will be waited     by the worker for at most 'ioblocktimeout' seconds. However this timeout applies only for un-encrypted     requests. Connections using SSL/TLS are not taking this timeout into account during reads, and may hang     longer.An unauthenticated attacker could repeatedly create hanging LDAP requests to hang all the workers,     resulting in a Denial of Service. (CVE-2019-3883)

  - A flaw was found in the 'deref' plugin of 389-ds-base where it could use the 'search' permission to     display attribute values. In some configurations, this could allow an authenticated attacker to view     private attributes, such as password hashes. (CVE-2019-14824)

An attacker with sufficiently high     privileges, such as root or Directory Manager, can query these files in order to retrieve plaintext     passwords. (CVE-2018-10871)

  - A flaw has been found in 389-ds-base versions 1.4.x.x before 1.4.1.3. When executed in verbose mode, the     dscreate and dsconf commands may display sensitive information, such as the Directory Manager password. An     attacker, able to see the screen or record the terminal standard error output, could use this flaw to gain     sensitive information. (CVE-2019-10224)

The remote CentOS Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the CESA-2019:3401 advisory.

  - 389-ds-base: using dscreate in verbose mode results in information disclosure (CVE-2019-10224)

  - 389-ds-base: Read permission check bypass via the deref plugin (CVE-2019-14824)

The version of 389-ds-base installed on the remote host is prior to 1.3.9.1-12.65. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS-2020-1334 advisory.

    It was found that encrypted connections did not honor the 'ioblocktimeout' parameter to end blocking     requests. As a result, an unauthenticated attacker could repeatedly start a sufficient number of encrypted     connections to block all workers, resulting in a denial of service.(CVE-2019-3883)

This update for 389-ds to version 1.4.0.26 fixes the following issues :

Security issues fixed :

CVE-2016-5416: Fixed an information disclosure where a anonymous user could read the default ACI (bsc#991201).

CVE-2018-1054: Fixed a denial of service via search filters in SetUnicodeStringFromUTF_8() (bsc#1083689).

CVE-2018-1089: Fixed a buffer overflow via large filter value (bsc#1092187).

CVE-2018-10871: Fixed an information disclosure in certain plugins leading to the disclosure of plaintext password to an privileged attackers (bsc#1099465).

CVE-2018-14638: Fixed a denial of service through a crash in delete_passwdPolicy () (bsc#1108674).

CVE-2018-14648: Fixed a denial of service caused by malformed values in search queries (bsc#1109609).

CVE-2018-10935: Fixed a denial of service related to ldapsearch with server side sort (bsc#1105606).

CVE-2019-3883: Fixed a denial of service caused by hanging LDAP requests over TLS (bsc#1132385).

CVE-2018-10871

By default nsslapd-unhashed-pw-switch was set to 'on'. So a copy of the unhashed password was kept in modifiers and was possibly logged in changelog and retroCL.

Unless it is used by some plugin it does not require to keep unhashed passwords. The nsslapd-unhashed-pw-switch option is now 'off' by default.

CVE-2018-10935

It was discovered that any authenticated user doing a search using ldapsearch with extended controls for server side sorting could bring down the LDAP server itself.

The fix is to check if we are able to index the provided value. If we are not, then slapd_qsort returns an error (LDAP_OPERATION_ERROR) .

For Debian 8 'Jessie', these problems have been fixed in version 1.3.3.5-4+deb8u2.

We recommend that you upgrade your 389-ds-base packages.
