(CVE-2007-4091) Impact An attacker may be able to execute arbitrary code using improperly handled directory names. Status F5 Product Development has assigned ID 476728, ID 477151, and ID 477150 (BIG-IP, BIG-IQ, and 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 be vulnerable Versions known to be not vulnerable Vulnerable component or feature BIG-IP LTM 11.0.0 - 11.5.1 10.0.0 - 10.2.4 11.6.0 rsync (ConfigSync) BIG-IP AAM 11.4.0 - 11.5.1 11.6.0 rsync (ConfigSync) BIG-IP AFM 11.3.0 - 11.5.1 11.6.0 rsync (ConfigSync) BIG-IP Analytics 11.0.0 - 11.5.1 11.6.0 rsync (ConfigSync) BIG-IP APM 11.0.0 - 11.5.1 10.1.0 - 10.2.4 11.6.0 rsync (ConfigSync) BIG-IP ASM 11.0.0 - 11.5.1 10.0.0 - 10.2.4 11.6.0 rsync (ConfigSync) BIG-IP Edge Gateway 11.0.0 - 11.3.0 10.1.0 - 10.2.4 None rsync (ConfigSync) BIG-IP GTM 11.0.0 - 11.5.1 10.0.0 - 10.2.4 11.6.0 rsync (ConfigSync) BIG-IP Link Controller 11.0.0 - 11.5.1 10.0.0 - 10.2.4 11.6.0 rsync (ConfigSync) BIG-IP PEM 11.3.0 - 11.5.1 11.6.0 rsync (ConfigSync) BIG-IP PSM 11.0.0 - 11.4.1 10.0.0 - 10.2.4 None rsync (ConfigSync) BIG-IP WebAccelerator 11.0.0 - 11.3.0 10.0.0 - 10.2.4 None rsync (ConfigSync) BIG-IP WOM 11.0.0 - 11.3.0 10.0.0 - 10.2.4 None rsync (ConfigSync) ARX None 6.0.0 - 6.4.0 None Enterprise Manager 3.0.0 - 3.1.1 2.1.0 - 2.3.0 None rsync FirePass None 7.0.0 6.0.0 - 6.1.0 None BIG-IQ Cloud 4.0.0 - 4.3.0 None rsync BIG-IQ Device 4.2.0 - 4.3.0 None rsync BIG-IQ Security 4.0.0 - 4.3.0 None rsync 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 table does not list any version in the column, then no upgrade candidate currently exists. To mitigate this vulnerability, you should ensure that the IP address used for ConfigSync is on a trusted network. Additionally, you should ensure TCP port 873 (tcp:873 or tcp:rsync) is disabled on self IP addresses. To do so, perform both of the following procedures: Ensuring that TCP port 873 is not allowed as a default service (allow-service default) Ensuring that your ConfigSync self IP is not configured with a Port Lockdown setting of Allow All (allow-service all) and does not specifically have TCP port 873 (tcp:rsync) enabled Ensuring that TCP port 873 is not allowed as a default service (allow-service default) Impact of procedure: Performing the following procedure should not have a negative impact on your system. Log in to the Traffic Management Shell (tmsh) by typing the following command: tmsh Output appears similar to the following example: net self-allow { defaults { ospf:any tcp:domain tcp:f5-iquery tcp:https tcp:snmp tcp:ssh udp:520 udp:cap udp:domain udp:f5-iquery udp:snmp } } If TCP port 873 (tcp:873 or tcp:rsync) is listed as a default allowed port, you should delete the entry by typing the following command: modify net self-allow defaults delete { tcp:rsync } Save the configuration by typing the following command: save sys config Ensuring that your ConfigSync self IP is not configured with a Port Lockdown setting of Allow All (allow-service all) and does not specifically have TCP port 873 (tcp:rsync) enabled Impact of procedure: Performing the following procedure should not have a negative impact on your system. Log in to the BIG-IP or Enterprise Manager Configuration utility. Navigate to Device Management> Devices. Select the device indicated as (Self). Navigate to Device Connectivity > ConfigSync. Note the IP address listed in Local Address. Navigate to Network > Self IPs. Click the self IP address that matches the Local Address from step 5. Ensure that the Port Lockdown setting is not set to Allow All, or Allow Custom with TCP port 873 (Rsync) added to the Custom List of allowed ports. For example, either delete TCP port 873 from the Custom List of allowed ports, or select Allow Default from the Port Lockdown menu. To save the configuration, click Update.
