README

go-msfdb

This is a tool for searching CVEs in Metasploit-Framework modules from msfdb-list. Metasploit modules are inserted at sqlite database(go-msfdb) can be searched by command line interface. In server mode, a simple Web API can be used.

Docker Deployment

There's a Docker image available docker pull vuls/go-msfdb. When using the container, it takes the same arguments as the normal command line.

Installation for local deployment

Search Modules by CVE(eg. CVE-2014-0160)

$ go run main.go search --type CVE --param CVE-2014-0160

Results: CVE-Metasploit Record
---------------------------------------

[*] CVE: CVE-2014-0160
  Name: openssl_heartbleed.rb
  Title: OpenSSL Heartbeat (Heartbleed) Information Leak
  Description: This module implements the OpenSSL Heartbleed attack. The problem exists in the handling of heartbeat requests, where a fake length can be used to leak memory data in the response. Services that support STARTTLS may also be vulnerable.  The module supports several actions, allowing for scanning, dumping of memory contents to loot, and private key recovery.  The LEAK_COUNT option can be used to specify leaks per SCAN or DUMP.  The repeat command can be used to make running the SCAN or DUMP many times more powerful. As in: repeat -t 60 run; sleep 2 To run every two seconds for one minute.

[*] CVE: CVE-2014-0160
  Name: openssl_heartbeat_client_memory.rb
  Title: OpenSSL Heartbeat (Heartbleed) Client Memory Exposure
  Description: This module provides a fake SSL service that is intended to leak memory from client systems as they connect. This module is hardcoded for using the AES-128-CBC-SHA1 cipher.

    "Description": "The RDP termdd.sys driver improperly handles binds to internal-only channel MS_T120, allowing a malformed Disconnect Provider Indication message to cause use-after-free. With a controllable data/size remote nonpaged pool spray, an indirect call gadget of the freed channel is used to achieve arbitrary code execution.  Windows 7 SP1 and Windows Server 2008 R2 are the only currently supported targets.  Windows 7 SP1 should be exploitable in its default configuration, assuming your target selection is correctly matched to the system's memory layout.  HKLM\\SYSTEM\\CurrentControlSet\\Control\\TerminalServer\\Winstations\\RDP-Tcp\\fDisableCam *needs* to be set to 0 for exploitation to succeed against Windows Server 2008 R2. This is a non-standard configuration for normal servers, and the target will crash if the aforementioned Registry key is not set!  If the target is crashing regardless, you will likely need to determine the non-paged pool base in kernel memory and set it as the GROOMBASE option.",
