Synopsis

The remote host is affected by multiple vulnerabilities.

Description

According to its self-reported version, the remote SonicWall firewall is running a version of SonicOS that is affected by multiple vulnerabilities:

- Stack overflow in the parsing of IPv4 packets IP options. (CVE-2019-12256)

- TCP Urgent Pointer = 0 leads to integer underflow (CVE-2019-12255)

- TCP Urgent Pointer state confusion caused by malformed TCP AO option (CVE-2019-12260)

- TCP Urgent Pointer state confusion during connect to a remote host (CVE-2019-12261)

- TCP Urgent Pointer state confusion due to race condition (CVE-2019-12263)

- Heap overflow in DHCP Offer/ACK parsing in ipdhcpc (CVE-2019-12257)

- TCP connection DoS via malformed TCP options (CVE-2019-12258)

- Handling of unsolicited Reverse ARP replies (Logical Flaw) (CVE-2019-12262)

- Logical flaw in IPv4 assignment by the ipdhcpc DHCP client (CVE-2019-12264)

- DoS via NULL dereference in IGMP parsing (CVE-2019-12259)

- IGMP Information leak via IGMPv3 specific membership report (CVE-2019-12265)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Upgrade to the relevant fixed version referenced in the vendor security advisory.

How to Run

Here is how to run the SonicWall SonicOS Firewall Multiple Management Vulnerabilities (URGENT/11) as a standalone plugin via the Nessus web user interface (https://localhost:8834/):

Click to start a New Scan.
Select Advanced Scan.
Navigate to the Plugins tab.
On the top right corner click to Disable All plugins.
On the left side table select Firewalls plugin family.
On the right side table select SonicWall SonicOS Firewall Multiple Management Vulnerabilities (URGENT/11) plugin ID 127107.
Specify the target on the Settings tab and click to Save the scan.
Run the scan.

Here are a few examples of how to run the plugin in the command line. Note that the examples below demonstrate the usage on the Linux / Unix platform.

Basic usage:

/opt/nessus/bin/nasl sonicwall_SNWLID-2019-0009.nasl -t <IP/HOST>

Run the plugin with audit trail message on the console:

/opt/nessus/bin/nasl -a sonicwall_SNWLID-2019-0009.nasl -t <IP/HOST>

Run the plugin with trace script execution written to the console (useful for debugging):

/opt/nessus/bin/nasl -T - sonicwall_SNWLID-2019-0009.nasl -t <IP/HOST>

Run the plugin with using a state file for the target and updating it (useful for running multiple plugins on the target):

/opt/nessus/bin/nasl -K /tmp/state sonicwall_SNWLID-2019-0009.nasl -t <IP/HOST>

Go back to menu.
