Vulnerability Information

Severity: Critical
Vulnerability Published: 2004-02-10
Patch Published: 2004-02-10
CVE [?]: CVE-2003-0818
CPE [?]: cpe:/o:microsoft:windows

Synopsis

Arbitrary code can be executed on the remote host.

Description

The remote Windows host has an ASN.1 library that could allow an attacker to execute arbitrary code on this host.

To exploit this flaw, an attacker would need to send a specially crafted ASN.1 encoded packet with improperly advertised lengths.

This particular check sent a malformed NTLM packet and determined that the remote host is not patched.

Solution

Microsoft has released patches for Windows NT, 2000, XP, and 2003.

Public Exploits

Target Network Port(s): 139, 445
Target Asset(s): N/A
Exploit Available: True (Metasploit Framework, Exploit-DB, Immunity Canvas, Core Impact)
Exploit Ease: Exploits are available

Here's the list of publicly known exploits and PoCs for verifying the MS04-007: ASN.1 Vulnerability Could Allow Code Execution (828028) (uncredentialed check) (NTLM) vulnerability:

Metasploit: exploit/windows/smb/ms04_007_killbill

How to Run

Here is how to run the MS04-007: ASN.1 Vulnerability Could Allow Code Execution (828028) (uncredentialed check) (NTLM) 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 Windows plugin family.
On the right side table select MS04-007: ASN.1 Vulnerability Could Allow Code Execution (828028) (uncredentialed check) (NTLM) plugin ID 12054.
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 windows_asn1_vuln_ntlm.nasl -t <IP/HOST>

Run the plugin with audit trail message on the console:

/opt/nessus/bin/nasl -a windows_asn1_vuln_ntlm.nasl -t <IP/HOST>

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

/opt/nessus/bin/nasl -T - windows_asn1_vuln_ntlm.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 windows_asn1_vuln_ntlm.nasl -t <IP/HOST>

Go back to menu.
