high Nessus Plugin ID 162523

Language:

Synopsis

The remote SUSE host is missing one or more security updates.

Description

The remote SUSE Linux SLES15 / SLES_SAP15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2022:2163-1 advisory.

- 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)

- An access control bypass vulnerability found in 389-ds-base. That mishandling of the filter that would yield incorrect results, but as that has progressed, can be determined that it actually is an access control bypass. This may allow any remote unauthenticated user to issue a filter that allows searching for database items they do not have access to, including but not limited to potentially userPassword hashes and other sensitive data. (CVE-2022-1949)

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

Solution

Update the affected packages.
