Metasploit modules for CVE-2017-0143

  • MS17-010 EternalRomance/EternalSynergy/EternalChampion SMB Remote Windows Code Execution
    Disclosure Date: 2017-03-14
    First seen: 2020-04-26
    exploit/windows/smb/ms17_010_psexec
    This module will exploit SMB with vulnerabilities in MS17-010 to achieve a write-what-where primitive. This will then be used to overwrite the connection session information with as an Administrator session. From there, the normal psexec payload code execution is done.

    This module will exploit SMB with vulnerabilities in MS17-010 to achieve a write-what-where primitive. This will then be used to overwrite the connection session information with as an Administrator session. From there, the normal psexec command execution is done.
  • MS17-010 SMB RCE Detection
    First seen: 2020-04-26
    auxiliary/scanner/smb/smb_ms17_010
    Uses information disclosure to determine if MS17-010 has been patched or not. Specifically, it connects to the IPC$ tree and attempts a transaction on FID 0. If the status returned is "STATUS_INSUFF_SERVER_RESOURCES", the machine does not have the MS17-010 patch.
