UNKNOWN Summary
389 Directory Server 1.3.1.x, 1.3.2.x before 1.3.2.27, and 1.3.3.x before 1.3.3.9 stores "unhashed" passwords even when the nsslapd-unhashed-pw-switch option is set to off, which allows remote authenticated users to obtain sensitive information by reading the Changelog.
Vulnerable Configurations
Common Weakness Enumeration (CWE)
Common Attack Pattern Enumeration and Classification (CAPEC)
- Subverting Environment Variable Values The attacker directly or indirectly modifies environment variables used by or controlling the target software. The attacker's goal is to cause the target software to deviate from its expected operation in a manner that benefits the attacker.
- Footprinting An attacker engages in probing and exploration activity to identify constituents and properties of the target. Footprinting is a general term to describe a variety of information gathering techniques, often used by attackers in preparation for some attack. It consists of using tools to learn as much as possible about the composition, configuration, and security mechanisms of the targeted application, system or network. Information that might be collected during a footprinting effort could include open ports, applications and their versions, network topology, and similar information. While footprinting is not intended to be damaging (although certain activities, such as network scans, can sometimes cause disruptions to vulnerable applications inadvertently) it may often pave the way for more damaging attacks.
- Exploiting Trust in Client (aka Make the Client Invisible) An attack of this type exploits a programs' vulnerabilities in client/server communication channel authentication and data integrity. It leverages the implicit trust a server places in the client, or more importantly, that which the server believes is the client. An attacker executes this type of attack by placing themselves in the communication channel between client and server such that communication directly to the server is possible where the server believes it is communicating only with a valid client. There are numerous variations of this type of attack.
- Browser Fingerprinting An attacker carefully crafts small snippets of Java Script to efficiently detect the type of browser the potential victim is using. Many web-based attacks need prior knowledge of the web browser including the version of browser to ensure successful exploitation of a vulnerability. Having this knowledge allows an attacker to target the victim with attacks that specifically exploit known or zero day weaknesses in the type and version of the browser used by the victim. Automating this process via Java Script as a part of the same delivery system used to exploit the browser is considered more efficient as the attacker can supply a browser fingerprinting method and integrate it with exploit code, all contained in Java Script and in response to the same web page request by the browser.
- Session Credential Falsification through Prediction This attack targets predictable session ID in order to gain privileges. The attacker can predict the session ID used during a transaction to perform spoofing and session hijacking.

Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section. The 389 Directory Server is an LDAPv3 compliant server. The base packages include the Lightweight Directory Access Protocol (LDAP) server and command-line utilities for server administration.

Red Hat Product Security has rated this update as having Important security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section. The 389 Directory Server is an LDAPv3 compliant server. The base packages include the Lightweight Directory Access Protocol (LDAP) server and command-line utilities for server administration. An information disclosure flaw was found in the way the 389 Directory Server stored information in the Changelog that is exposed via the 'cn=changelog' LDAP sub-tree. An unauthenticated user could in certain cases use this flaw to read data from the Changelog, which could include sensitive information such as plain-text passwords. (CVE-2014-8105) It was found that when the nsslapd-unhashed-pw-switch 389 Directory Server configuration option was set to 'off', it did not prevent the writing of unhashed passwords into the Changelog. This could potentially allow an authenticated user able to access the Changelog to read sensitive information. (CVE-2014-8112) The CVE-2014-8105 issue was discovered by Petr Spacek of the Red Hat Identity Management Engineering Team, and the CVE-2014-8112 issue was discovered by Ludwig Krispenz of the Red Hat Identity Management Engineering Team. Enhancements : * Added new WinSync configuration parameters: winSyncSubtreePair for synchronizing multiple subtrees, as well as winSyncWindowsFilter and winSyncDirectoryFilter for synchronizing restricted sets by filters. (BZ# 746646) * It is now possible to stop, start, or configure plug-ins without the need to restart the server for the change to take effect. (BZ#994690) * Access control related to the MODDN and MODRDN operations has been updated: the source and destination targets can be specified in the same access control instruction. (BZ#1118014) * The nsDS5ReplicaBindDNGroup attribute for using a group distinguished name in binding to replicas has been added. (BZ#1052754) * WinSync now supports range retrieval. If more than the MaxValRange number of attribute values exist per attribute, WinSync synchronizes all the attributes to the directory server using the range retrieval. (BZ#1044149) * Support for the RFC 4527 Read Entry Controls and RFC 4533 Content Synchronization Operation LDAP standards has been added. (BZ#1044139, BZ# 1044159) * The Referential Integrity (referint) plug-in can now use an alternate configuration area. The PlugInArg plug-in configuration now uses unique configuration attributes. Configuration changes no longer require a server restart. (BZ#1044203) * The logconv.pl log analysis tool now supports gzip, bzip2, and xz compressed files and also TAR archives and compressed TAR archives of these files. (BZ#1044188) * Only the Directory Manager could add encoded passwords or force users to change their password after a reset. Users defined in the passwordAdminDN attribute can now also do this. (BZ#1118007) * The 'nsslapd-memberofScope' configuration parameter has been added to the MemberOf plug-in. With MemberOf enabled and a scope defined, moving a group out of scope with a MODRDN operation failed. Moving a member entry out of scope now correctly removes the memberof value. (BZ#1044170) * The alwaysRecordLoginAttr attribute has been addded to the Account Policy plug-in configuration entry, which allows to distinguish between an attribute for checking the activity of an account and an attribute to be updated at successful login. (BZ#1060032) * A root DSE search, using the ldapsearch command with the '-s base -b ''' options, returns only the user attributes instead of the operational attributes. The 'nsslapd-return-default' option has been added for backward compatibility. (BZ#1118021) * The configuration of the MemberOf plug-in can be stored in a suffix mapped to a back-end database, which allows MemberOf configuration to be replicated. (BZ#1044205) * Added support for the SSL versions from the range supported by the NSS library available on the system. Due to the POODLE vulnerability, SSLv3 is disabled by default even if NSS supports it.
