This vulnerability requires valid user account credentials and access to the Configuration utility. This flaw exists when APM is configured, and exposes session details within the access logs. If the BIG-IP APM system is not in use, the vulnerability still exists; however, there is no data stored in the log files in question when the BIG-IP APM system is not actively in use. (CVE-2016-1497) Impact An unauthorized user might gain access to APM access logs. Security Issue Status F5 Product Development has assigned ID 539923 to this vulnerability, and has evaluated the currently supported releases for potential vulnerability.

The settings of the anonymous IPsec IKE peer object allow an arbitrary peer to establish IKE phase 1 without certificate validation or a pre-shared key which may expose phase 2 negotiations to a brute force attack. (CVE-2016-5736) Impact For BIG-IP systems configured with IPsec tunnels, the default anonymous IPsec IKE peer configuration can allow a remote attacker to cause a denial-of-service (DoS) attack or inject traffic into local networks.

If the table lists only an older version than what you are currently running, or does not list a non-vulnerable version, then no upgrade candidate currently exists. To mitigate this vulnerability, you can disable the anonymous IPsec IKE peer listener (if not in use). However, if you want to use the anonymous listener, you should ensure that the Verify Certificate option is enabled, or configure the Authentication Method option to use the Preshared Key method if certificates are not in use. To do so, perform the following procedures: Disabling the anonymous IPsec IKE peer listener Enabling the Verify Certificate option for the anonymous IPsec IKE peer listener Configuring the Authentication Method option to use the Preshared Key method for the anonymous IPsec IKE peer listener Disabling the anonymous IPsec IKE peer listener Impact of action: The BIG-IP system will no longer listen for IPsec IKE peers unless another peer listener has been configured. 1. Log in to the Configuration utility. 2. Navigate to Network > IPsec > IKE Peers. 3. Select the anonymous IKE peer. 4. For the State option, select Disabled. 5. Click Update. Enabling the Verify Certificate option for the anonymous IPsec IKE peer listener Impact of action: IPsec IKE peers will be required to provide a valid certificate or negotiation will fail. 1. Log in to the Configuration utility. 2. Navigate to Network > IPsec > IKE Peers. 3. Select the anonymous IKE peer. 4. In the IKE Phase 1 Credentials section, select the Verify Peer Certificate check box. Enabling the Verify Peer Certificate option allows you to configure the following: - - Trusted Certificate Authorities - - Certificate Revocation List (CRL) - - Peer Certificate 5. Click Update. Configuring the Authentication Method option to use the Preshared Key method for the anonymous IPsec IKE peer listener Impact of action: IPsec IKE peers will be required to provide the specified preshared key or negotiation will fail. 1. Log in to the Configuration utility. 2. Navigate to Network > IPsec > IKE Peers. 3. Select the anonymous IKE peer. 4. In the IKE Phase 1 Credentials section, select Preshared Key for the Authentication Method option. Selecting the Preshared Key method provides following fields: - - Preshared Key - - Verify Preshared Key 5. In the Preshared Key field, enter the string that IKE peers will share for authenticating each other. 6. In the Verify Preshared Key field, re-enter the string that IKE peers will share for authenticating each other. 7. Click Update.

F5 is still researching the issue for the products indicated, and will update this article with the most current information as soon as it has been confirmed. F5 Technical Support does not have any additional information on this issue. 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. If the table lists only an older version than what you are currently running, or does not list a non-vulnerable version, then no upgrade candidate currently exists. This vulnerability exists regardless of the provisioning level configured for BIG-IP APM and is only exploitable by an authenticated user. To mitigate this vulnerability, you should permit management access to F5 products only over a secure network and limit shell access to only trusted users. For more information, refer to SOL13309: Restricting access to the Configuration utility by source IP address (11.x - 12.x) and SOL13092: Overview of securing access to the BIG-IP system.
