Description
BIG-IP configurations using Active Directory, LDAP, or Client Certificate LDAP for management authentication with multiple servers are exposed to a vulnerability which allows an authentication bypass. This can result in a complete compromise of the system. This issue only impacts specific engineering hotfixes using the aforementioned authentication configuration. NOTE: This vulnerability does not affect any of the BIG-IP major, minor or maintenance releases you obtained from downloads.f5.com. The affected Engineering Hotfix builds are as follows: Hotfix-BIGIP-14.1.0.3.0.79.6-ENG.iso, Hotfix-BIGIP-14.1.0.3.0.97.6-ENG.iso, Hotfix-BIGIP-14.1.0.3.0.99.6-ENG.iso, Hotfix-BIGIP-14.1.0.5.0.15.5-ENG.iso, Hotfix-BIGIP-14.1.0.5.0.36.5-ENG.iso, Hotfix-BIGIP-14.1.0.5.0.40.5-ENG.iso, Hotfix-BIGIP-14.1.0.6.0.11.9-ENG.iso, Hotfix-BIGIP-14.1.0.6.0.14.9-ENG.iso, Hotfix-BIGIP-14.1.0.6.0.68.9-ENG.iso, Hotfix-BIGIP-14.1.0.6.0.70.9-ENG.iso, Hotfix-BIGIP-14.1.2.0.11.37-ENG.iso, Hotfix-BIGIP-14.1.2.0.18.37-ENG.iso, Hotfix-BIGIP-14.1.2.0.32.37-ENG.iso, Hotfix-BIGIP-14.1.2.1.0.46.4-ENG.iso, Hotfix-BIGIP-14.1.2.1.0.14.4-ENG.iso, Hotfix-BIGIP-14.1.2.1.0.16.4-ENG.iso, Hotfix-BIGIP-14.1.2.1.0.34.4-ENG.iso, Hotfix-BIGIP-14.1.2.1.0.97.4-ENG.iso, Hotfix-BIGIP-14.1.2.1.0.99.4-ENG.iso, Hotfix-BIGIP-14.1.2.1.0.105.4-ENG.iso, Hotfix-BIGIP-14.1.2.1.0.111.4-ENG.iso, Hotfix-BIGIP-14.1.2.1.0.115.4-ENG.iso, Hotfix-BIGIP-14.1.2.1.0.122.4-ENG.iso, Hotfix-BIGIP-15.0.1.0.33.11-ENG.iso, Hotfix-BIGIP-15.0.1.0.48.11-ENG.iso
