RHEL 8 : pki-core:10.6 (RHSA-2021:2235)

high Nessus Plugin ID 150291

Language:

Synopsis

The remote Red Hat host is missing a security update for pki-core:10.6.

Description

The remote Redhat Enterprise Linux 8 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2021:2235 advisory.

 The Public Key Infrastructure (PKI) Core contains fundamental packages required by Red Hat Certificate System.

 Security Fix(es):

 * pki-server: Dogtag installer pkispawn logs admin credentials into a world-readable log file (CVE-2021-3551)

 The PKI installer pkispawn logs admin credentials into a world-readable log file. It also looks like the installer is passing the password as an insecure command line argument. The credentials are the 389-DS LDAP server's Directory Manager credentials. The Directory Manager is 389-DS' equivalent of unrestricted root account. The user bypasses permission checks and grants full access to data. In an IdM / FreeIPA installation the DM user is able to read and manipulate Kerberos KDC master password, Kerberos keytabs, hashed user passwords, and more.
 Any and all IdM and FreeIPA installations with PKI 10.10 should be considered compromised.

 For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux 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

Update the RHEL pki-core:10.6 package based on the guidance in RHSA-2021:2235.
