medium Nessus Plugin ID 179749

Language:

Synopsis

The remote Amazon Linux 2023 host is missing a security update.

Description

It is, therefore, affected by a vulnerability as referenced in the ALAS2023-2023-280 advisory.

A flaw was found in Bouncy Castle 1.73. This issue targets the fix of LDAP wild cards. Before the fix there was no validation for the X.500 name of any certificate, subject, or issuer, so the presence of a wild card may lead to information disclosure. This could allow a malicious user to obtain unauthorized information via blind LDAP Injection, exploring the environment and enumerating data. The exploit depends on the structure of the target LDAP directory as well as what kind of errors are exposed to the user.
(CVE-2023-33201)

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

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

Solution

Run 'dnf update bouncycastle --releasever 2023.1.20230809' to update your system.
