(CVE-2012-2333) Impact Remote attackers may be able to cause a denial-of-service (DoS). Status F5 Product Development has assigned ID 376840 (BIG-IP and Enterprise Manager) and ID 410742 (ARX) 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 be vulnerable Versions known to be not vulnerable Vulnerable component or feature BIG-IP LTM 11.0.0 - 11.2.1 11.3.0 - 11.5.1 Configuration utility 10.1.0 - 10.2.4 COMPAT SSL ciphers BIG-IP AAM None 11.4.0 - 11.5.1 None BIG-IP AFM None 11.3.0 - 11.5.1 None BIG-IP 11.0.0 - 11.2.1 11.3.0 - 11.5.1 Configuration utility Analytics COMPAT SSL ciphers BIG-IP APM 11.0.0 - 11.2.1 11.3.0 - 11.5.1 Configuration utility 10.1.0 - 10.2.4 COMPAT SSL ciphers BIG-IP ASM 11.0.0 - 11.2.1 11.3.0 - 11.5.1 Configuration utility 10.1.0 - 10.2.4 COMPAT SSL ciphers BIG-IP 11.0.0 - 11.2.1 11.3.0 Configuration utility Edge Gateway 10.1.0 - 10.2.4 COMPAT SSL ciphers BIG-IP GTM 11.0.0 - 11.2.1 11.3.0 - 11.5.1 Configuration utility 10.1.0 - 10.2.4 COMPAT SSL ciphers BIG-IP Link 11.0.0 - 11.2.1 11.3.0 - 11.5.1 Configuration utility Controller 10.1.0 - 10.2.4 COMPAT SSL ciphers BIG-IP PEM None 11.3.0 - 11.5.1 None BIG-IP PSM 11.0.0 - 11.2.1 11.3.0 - 11.4.1 Configuration utility 10.1.0 - 10.2.4 COMPAT SSL ciphers BIG-IP 11.0.0 - 11.2.1 11.3.0 Configuration utility WebAccelerator 10.1.0 - 10.2.4 COMPAT SSL ciphers BIG-IP WOM 11.0.0 - 11.2.1 11.3.0 Configuration utility 10.1.0 - 10.2.4 COMPAT SSL ciphers ARX 6.0.0 - 6.4.0 None ARX GUI Enterprise 3.0.0 3.1.0 - 3.1.1 Configuration utility Manager 2.1.0 - 2.3.0 FirePass None 7.0.0 None 6.0.0 - 6.1.0 BIG-IQ Cloud None 4.0.0 - 4.3.0 None BIG-IQ Device None 4.2.0 - 4.3.0 None BIG-IQ Security None 4.0.0 - 4.3.0 None Recommended action You can eliminate this vulnerability by running a version listed in the Versions known to be not vulnerable column in the previous table. If the Versions known to be not vulnerable column does not list a version that is higher than the version you are running, then no upgrade candidate currently exists. Mitigating this vulnerability To mitigate this vulnerability, you should consider the following recommendations: Consider denying access to the Configuration utility and using only the command line and tmsh utility until the BIG-IP system is updated. If that is not possible, F5 recommends that you access the Configuration utility over only a secure network. If SSL profiles are configured to use COMPAT ciphers, consider reconfiguring the profiles to use ciphers from the NATIVE SSL stack. For information about the NATIVE and COMPAT ciphers, refer to the following articles: SOL13163: SSL ciphers supported on BIG-IP platforms (11.x) SOL13171: Configuring the cipher strength for SSL profiles (11.x) SOL13187: COMPAT SSL ciphers are no longer included in standard cipher strings ARX 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 table does not list any version in the column, then no upgrade candidate currently exists. To mitigate this vulnerability, you should permit access to the ARX GUI only over a secure network.
