(CVE-2015-4910) Impact This vulnerability may allow remote authenticated users to affect availability by way of unknown vectors. However, Enterprise Manager systems have default mitigations in place through local user authentication requirements and iptables (EM 3.x) that downgrade the access vector for these vulnerabilities limited to local and authenticated users. Security Issue Status F5 Product Development has assigned ID 556684 (Enterprise Manager) 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 to Versions known to Severity Vulnerable component be vulnerable be not vulnerable or feature Enterprise Manager 3.0.0 - 3.1.1 None Medium None Vulnerability Recommended Actions If you are running a version listed in the Versions known to be vulnerable column, you can eliminate this vulnerability by upgrading to a version listed in the Versions known to be not vulnerable column.
