RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Doc Type: Bug Fix
Doc Text:
Directory Server no longer logs sensitive information Previously, when the "Trace function calls" option was enabled in the "nsslapd-errorlog-level" parameter, Directory Server logged all attributes into the error log file, including attributes containing sensitive information. A patch has been applied to filter out values of sensitive attributes. As a result, Directory Server no longer logs sensitive information.

Description Noriko Hosoi 2016-10-21 20:13:01 UTC 
This bug is created as a clone of upstream ticket:
https://fedorahosted.org/389/ticket/49009

If the logging level is set to debugging args the full mod apreations are logged, including prehashed data.
This is only accessible in the error log, and cannot be triggered or used by an external client, but should be hardended
Comment 3 Simon Pichugin 2016-12-06 18:16:23 UTC 
Build tested:
389-ds-base-1.2.11.15-85.el6.x86_64

Verification steps:
[1] Set up MMR.

[2] Add a user entry, - uid=tuser,dc=example,dc=com
[root@qeos-66 dirsrvtests]# ldapsearch -h localhost -p 38941 -D "cn=directory manager" -w password -b "uid=tuser,dc=example,dc=com"

dn: uid=tuser,dc=example,dc=com
cn: tuser
objectClass: inetorgperson
objectClass: organizationalPerson
objectClass: person
objectClass: top
sn: tuser
mail: tuser
uid: tuser
userPassword:: e1NTSEF9NXVya1cwcmt4MEliTnBDR0FtVUlGdmMrZnpnakdpdFJOL3dkTlE9PQ=
 =

[3] Enable the trace level error log on both masters. 
1 — Trace function calls. Logs a message when the server enters and exits a function.
4 — Heavy trace output debugging.
16384 — default

[root@qeos-66 dirsrvtests]# ldapmodify -h localhost -p 38941 -D "cn=directory manager" -w password
dn: cn=config
changetype: modify
replace: nsslapd-errorlog-level
nsslapd-errorlog-level: 16389

modifying entry "cn=config"

[root@qeos-66 dirsrvtests]# ldapmodify -h localhost -p 38942 -D "cn=directory manager" -w password
dn: cn=config
changetype: modify
replace: nsslapd-errorlog-level
nsslapd-errorlog-level: 16389

modifying entry "cn=config"

[4] Modify the userPassword of the user entry, uid=tuser,dc=example,dc=com
[root@qeos-66 dirsrvtests]# ldapmodify -h localhost -p 38941 -D "cn=directory manager" -w password
dn: uid=tuser,dc=example,dc=com
changetype: modify
delete: userpassword

modifying entry "uid=tuser,dc=example,dc=com"

dn: uid=tuser,dc=example,dc=com
changetype: modify
add: userpassword
userpassword: newpass

modifying entry "uid=tuser,dc=example,dc=com"

dn: uid=tuser,dc=example,dc=com
changetype: modify
replace: userpassword
userpassword: newnewpass

modifying entry "uid=tuser,dc=example,dc=com"

[5] Grep the error log with "unhashed#user#password" as well as the password string. 
[root@qeos-66 ds]# grep "unhashed#user#password" /var/log/dirsrv/slapd-master_2/errors
[06/Dec/2016:12:42:21 -0500] -  add: unhashed#user#password

[06/Dec/2016:12:42:26 -0500] -    replace: unhashed#user#password
[06/Dec/2016:12:42:26 -0500] - removing entire attribute unhashed#user#password

[root@qeos-66 ds]# grep "unhashed#user#password" /var/log/dirsrv/slapd-master_1/errors
[06/Dec/2016:12:42:21 -0500] -    add: unhashed#user#password

[06/Dec/2016:12:42:26 -0500] - => index_addordel_values_ext_sv( "unhashed#user#password", 12 )
ce: unhashed#user#password

There is no plain text password. Marking as VERIFIED.
