sol15548: Rsync sender.c vulnerability - CVE-2007-4091 Security 
AdvisorySecurity Advisory

Original Publication Date: 09/04/2014

Description

Multiple off-by-one errors in the sender.c in rsync 2.6.9 might allow remote 
attackers to execute arbitrary code via directory names that are not properly
handled when calling the f_name function. (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

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.

sol15549: Rsync vulnerability - CVE-2007-6199 Security AdvisorySecurity 
Advisory

Original Publication Date: 09/04/2014

Description

rsync before 3.0.0pre6, when running a writable rsync daemon that is not using
chroot, allows remote attackers to access restricted files via unknown vectors
that cause rsync to create a symlink that points outside of the module's 
hierarchy. (CVE-2007-6199)

Impact

An attacker may be able to gain access to restricted files.

Status

F5 Product Development has assigned ID 476738, ID 477154, and ID 477153

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

List the default services allowed by the allow-service default setting by
typing the following command:

	list net self-allow
	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 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.
