A flaw was found in the PKI-server, where the spkispawn command, when run in debug mode, stores admin credentials in the installation log file. This flaw allows a local attacker to retrieve the file to obtain the admin password and gain admin privileges to the Dogtag CA manager. The highest threat from this vulnerability is to confidentiality.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

    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.
