Foundation<br>Citrix, Inc.</p><p>Versions Afffected:<br>Apache CloudStack 4.3, 4.4</p><p>Description:<br>Apache CloudStack may be configured to authenticate LDAP users. When so configured, it performs a simple LDAP bind with the name and password provided by a user. Simple LDAP binds are defined with three mechanisms (RFC 4513): 1) username and password; 2) unauthenticated if only a username is specified; and 3) anonymous if neither username or password is specified. Currently, Apache CloudStack does not check if the password was provided which could allow an attacker to bind as an unauthenticated user.</p><p>Mitigation:<br>Users of Apache CloudStack 4.4 and derivatives should update to the latest version (4.4.2)</p><p>An updated release for Apache CloudStack 4.3.2 is in testing. Until that is released, we recommend following the mitigation below:</p><p>By default, many LDAP servers are not configured to allow unauthenticated binds. If the LDAP server in use allow this behaviour, a potential interim solution would be to consider disabling unauthenticated binds.</p><p>Credit:<br>This issue was identified by the Citrix Security Team.</p></div><footer class="row docusaurus-mt-lg blogPostFooterDetailsFull_mRVl"><div class="col"><b>Tags:</b><ul class="tags_jXut padding--none margin-left--sm"><li class="tag_QGVx"><a class="tag_zVej tagRegular_sFm0" href="/blog/tags/announcement">announcement</a></li></ul></div><div class="col margin-top--sm"><a href="https://github.com/apache/cloudstack-www/tree/main/blog/2014-12-08-cve_2014_7807_apache_cloudstack.md" target="_blank" rel="noreferrer noopener" class="theme-edit-this-page"><svg fill="currentColor" height="20" width="20" viewBox="0 0 40 40" class="iconEdit_Z9Sw" aria-hidden="true"><g><path d="m34.5 11.7l-3 3.1-6.3-6.3 3.1-3q0.5-0.5 1.2-0.5t1.1 0.5l3.9 3.9q0.5 0.4 0.5 1.1t-0.5 1.2z m-29.5 17.1l18.4-18.5 6.3 6.3-18.4 18.4h-6.3v-6.2z"></path></g></svg>Edit this page</a></div></footer></article><nav class="pagination-nav docusaurus-mt-lg" aria-label="Blog post page navigation"><a class="pagination-nav__link pagination-nav__link--prev" href="/blog/announce_announcing_apache_cloudstack_4"><div class="pagination-nav__sublabel">Newer Post</div><div class="pagination-nav__label">[ANNOUNCE] Announcing Apache CloudStack 4.3.2</div></a><a class="pagination-nav__link pagination-nav__link--next" href="/blog/the_apache_cloudstack_project_announces1"><div class="pagination-nav__sublabel">Older Post</div><div class="pagination-nav__label">The Apache CloudStack Project Announces Apache™ CloudMonkey™ v5.3.0</div></a></nav></main></div></div></div><footer class="footer footer--dark"><div class="container container-fluid"><div class="footer__bottom text--center"><div class="margin-bottom--sm"><a href="https://cloudstack.apache.org/" rel="noopener noreferrer" class="footerLogoLink_BH7S"><img src="/img/ACS_logo_slogan.svg" alt="Apache CloudStack logo" class="themedImage_ToTc themedImage--light_HNdA footer__logo"><img src="/img/ACS_logo_slogan.svg" alt="Apache CloudStack logo" class="themedImage_ToTc themedImage--dark_i4oU footer__logo"></a></div><div class="footer__copyright"> |
