CVE-2014-2828 (GCVE-0-2014-2828)

Vulnerability from cvelistv5 – Published: 2014-04-15 14:00 – Updated: 2024-08-06 10:28

Summary

The V3 API in OpenStack Identity (Keystone) 2013.1 before 2013.2.4 and icehouse before icehouse-rc2 allows remote attackers to cause a denial of service (CPU consumption) via a large number of the same authentication method in a request, aka "authentication chaining."

Severity ?

Summary

Red Hat Security Advisory: openstack-keystone security and bug fix update

Notes

Topic

Updated openstack-keystone packages that fix two security issues and multiple bugs are now available for Red Hat Enterprise Linux OpenStack Platform 4.0. 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.

Details

The OpenStack Identity service (keystone) authenticates and authorizes OpenStack users by keeping track of users and their permitted activities. The Identity service supports multiple forms of authentication, including user name and password credentials, token-based systems, and AWS-style logins. A flaw was found in the keystone V3 API. An attacker could send a single request with the same authentication method multiple times, possibly leading to a denial of service due to generating excessive load with minimal requests. Only keystone setups with the V3 API enabled were affected by this issue. (CVE-2014-2828) A flaw was found in the keystone catalog URL replacement. A user with permissions to register an endpoint could use this flaw to leak configuration data, including the master admin_token. Only keystone setups that allow non-cloud-admin users to create endpoints were affected by this issue. (CVE-2014-3621) Red Hat would like to thank the OpenStack project for reporting CVE-2014-3621. Upstream acknowledges Brant Knudson from IBM as the original reporter of this issue. The openstack-keystone packages have been upgraded to upstream version 2013.2.4, which provides a number of bug fixes over the previous version. (BZ#1146083) This update fixes the following bugs: * When using an LDAP back end, the Identity service failed with a 'Bad search filter' error whenever a token request was made for a user whose ID contained a comma (for example, 'Doe, John'). However, if the user's ID contained no comma ('John Doe'), the Identity service grants token requests as expected. This was because the LDAP back end code of the Identity server did not properly escape special characters when creating search filters. This update adds the necessary escaping, thereby allowing the Identity server to perform LDAP search operations correctly. (BZ#1099628) * Previously, if the Identity service encountered a failed connection to a message broker, re-connection attempts kept failing as well. This was because the Identity service tried to reconnect to the same failing message broker, even if there were multiple hosts configured. This has been fixed by making the reconnect() implementation select the next broker in the list. As a result, when multiple broker hosts are provided, the Identity service will try the next one in the list at every connection attempt. This means that non-failure reconnect attempts will also switch from the current broker to the next in the list. Hence, users should not rely on any particular order when using brokers from the list. (BZ#1082669) * The Identity service now logs successful authentications of users. In previous releases, only authentication failures were logged. (BZ#1098635) * When using the LDAP back end and connecting to Active Directory anonymously, trying to use the top-level suffix as the user_tree_dn (or tenant/role_tree_dn) failed with a communication error. This is because the Identity service attempted to chase returned referrals, which is not allowed by default in Active Directory for security reasons. This update adds a new configuration option to disable referral chasing for LDAP search operations, namely chase_referrals. When this option is disabled, the Identity service will skip over any returned referrals without chasing them. (BZ#1093833) All openstack-keystone users are advised to upgrade to these updated packages, which correct these issues.

        "text": "The OpenStack Identity service (keystone) authenticates and authorizes\nOpenStack users by keeping track of users and their permitted activities.\nThe Identity service supports multiple forms of authentication, including\nuser name and password credentials, token-based systems, and AWS-style\nlogins.\n\nA flaw was found in the keystone V3 API. An attacker could send a single\nrequest with the same authentication method multiple times, possibly\nleading to a denial of service due to generating excessive load with\nminimal requests. Only keystone setups with the V3 API enabled were\naffected by this issue. (CVE-2014-2828)\n\nA flaw was found in the keystone catalog URL replacement. A user with\npermissions to register an endpoint could use this flaw to leak\nconfiguration data, including the master admin_token. Only keystone setups\nthat allow non-cloud-admin users to create endpoints were affected by this\nissue. (CVE-2014-3621)\n\nRed Hat would like to thank the OpenStack project for reporting\nCVE-2014-3621. Upstream acknowledges Brant Knudson from IBM as the original\nreporter of this issue.\n\nThe openstack-keystone packages have been upgraded to upstream version\n2013.2.4, which provides a number of bug fixes over the previous version.\n(BZ#1146083)\n\nThis update fixes the following bugs:\n\n* When using an LDAP back end, the Identity service failed with a \u0027Bad\nsearch filter\u0027 error whenever a token request was made for a user whose ID\ncontained a comma (for example, \u0027Doe, John\u0027). However, if the user\u0027s ID\ncontained no comma (\u0027John Doe\u0027), the Identity service grants token requests\nas expected. This was because the LDAP back end code of the Identity server\ndid not properly escape special characters when creating search filters.\nThis update adds the necessary escaping, thereby allowing the Identity\nserver to perform LDAP search operations correctly. (BZ#1099628)\n\n* Previously, if the Identity service encountered a failed connection to a\nmessage broker, re-connection attempts kept failing as well. This was\nbecause the Identity service tried to reconnect to the same failing message\nbroker, even if there were multiple hosts configured. This has been fixed\nby making the reconnect() implementation select the next broker in the\nlist. As a result, when multiple broker hosts are provided, the Identity\nservice will try the next one in the list at every connection attempt.\nThis means that non-failure reconnect attempts will also switch from the\ncurrent broker to the next in the list. Hence, users should not rely on any\nparticular order when using brokers from the list. (BZ#1082669)\n\n* The Identity service now logs successful authentications of users.\nIn previous releases, only authentication failures were logged.\n(BZ#1098635)\n\n* When using the LDAP back end and connecting to Active Directory\nanonymously, trying to use the top-level suffix as the user_tree_dn (or\ntenant/role_tree_dn) failed with a communication error. This is because the\nIdentity service attempted to chase returned referrals, which is not\nallowed by default in Active Directory for security reasons. This update\nadds a new configuration option to disable referral chasing for LDAP search\noperations, namely chase_referrals. When this option is disabled, the\nIdentity service will skip over any returned referrals without chasing\nthem. (BZ#1093833)\n\nAll openstack-keystone users are advised to upgrade to these updated\npackages, which correct these issues.",
