(CVE-2015-4637) Impact An attacker may be able to obtain an authentication token from the representational state transfer (REST) application programming interface (API) for known, or guessed, Lightweight Directory Access Protocol (LDAP) user accounts. Status F5 Product Development has assigned ID 527647 (BIG-IQ) to this vulnerability, and has evaluated the currently supported releases for potential vulnerability. To determine if your release is known to be vulnerable, the components or features that are affected by the vulnerability, and for information about releases or hotfixes that address the vulnerability, refer to the following table: Product Versions known Versions known to Severity Vulnerable component or feature to be vulnerable be not vulnerable BIG-IQ Cloud 4.4.0 - 4.5.0 4.5.0 HF2 Critical REST API 4.4.0 HF2 4.0.0 - 4.3.0 BIG-IQ Device 4.4.0 - 4.5.0 4.5.0 HF2 Critical REST API 4.4.0 HF2 4.2.0 - 4.3.0 BIG-IQ Security 4.4.0 - 4.5.0 4.5.0 HF2 Critical REST API 4.4.0 HF2 4.0.0 - 4.3.0 BIG-IQ ADC 4.5.0 4.5.0 HF2 Critical REST API Note: As of February 17, 2015, AskF5 Security Advisory articles include the Severity value. Security Advisory articles published before this date do not list a Severity value. Recommended Action If the previous table lists a version in the Versions known to be not vulnerable column, you can eliminate this vulnerability by upgrading to the listed version. If the listed version is older than the version you are currently running, or if the table does not list any version in the column, then no upgrade candidate currently exists. F5 responds to vulnerabilities in accordance with the Severity values published in the previous table. The Severity values and other security vulnerability parameters are defined in SOL4602: Overview of the F5 security vulnerability response policy. To mitigate this vulnerability, you can disable LDAP remote authentication on the BIG-IQ system, or disable anonymous binding for the LDAP server.
