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.

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)

  - 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)

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

The remote Debian 10 host has packages installed that are affected by multiple vulnerabilities as referenced in the dla-3399 advisory.

  - 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)

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)

  - When using a sync_repl client in 389-ds-base, an authenticated attacker can cause a NULL pointer     dereference using a specially crafted query, causing a crash. (CVE-2021-3514)

  - A flaw was found in 389-ds-base. If an asterisk is imported as password hashes, either accidentally or     maliciously, then instead of being inactive, any password will successfully match during authentication.
    This flaw allows an attacker to successfully authenticate as a user whose password was disabled.
    (CVE-2021-3652)

  - A double-free was found in the way 389-ds-base handles virtual attributes context in persistent searches.
    An attacker could send a series of search requests, forcing the server to behave unexpectedly, and crash.
    (CVE-2021-4091)

  - A vulnerability was discovered in the 389 Directory Server that allows an unauthenticated attacker with     network access to the LDAP port to cause a denial of service. The denial of service is triggered by a     single message sent over a TCP connection, no bind or other authentication is required. The message     triggers a segmentation fault that results in slapd crashing. (CVE-2022-0918)

  - A vulnerability was found in the 389 Directory Server that allows expired passwords to access the database     to cause improper authentication. (CVE-2022-0996)

  - A flaw was found In 389-ds-base. When the Content Synchronization plugin is enabled, an authenticated user     can reach a NULL pointer dereference using a specially crafted query. This flaw allows an authenticated     attacker to cause a denial of service. This CVE is assigned against an incomplete fix of CVE-2021-3514.
