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.

    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)

    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)

    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)

    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)

    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)

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

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

According to the version of the 389-ds-base packages installed, the EulerOS installation on the remote host is affected by the following vulnerability :

  - 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.

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.
