to provide consistent support for various exploits and OS SMB Commands.
Reintroduces smb_cmd_trans_query_path_info_network for use with the Struts2 JSP injection vulnerability.
Reintroduces smb_cmd_trans_query_file_info_basic for common use with rundll32.
Corrects some issues with filename formatting and pattern matching for file requests (can still be improved).
This commit adds several constants for TRANS2, QUERY_PATH_INFO, MAX_DATA_COUNT,
and NT2 FLAG2 Bits to smb/constants.rb, which have then been utilised in smb/server.rb
to reduce the use of magic values.
This will fix issue #4119. A bug in the find_first method in rex
SMB.
When the SMB client requests a TRANS2_FIND_FIRST2 for retriving
information about what items a directory has, the server returns
a response that contains an SID - a search identifier for the
transaction. If the SMB client wants more data, it must send a
TRANS2_FIND_NEXT2 request with the same SID. And then the server
will continue sending more until it runs out.
The root cause of this bug is that after the TRANS2_FIND_FIRST2
request is sent, our SMB's find_first method forgets the SID at
the end of the loop (out of scope).
This commit adds support for the TRANS2 request 'query file info
network' (smb_cmd_trans_query_file_info_network) used in some SMB client
requests. This adds specific support for functions used by Apache Tomcat
in the Struts2 JSP injection exploit (CVE-2014-0094).
These additions queue up support for the SMB functions used by the
ms13_071_theme expoit developed by Juan Vazquez, including support for
the FIND_FIRST2 functions:
* Find File Both Directory Info
* Find File Names Info
Additionally this commit fixes a few bugs in how the client SMB payload
is handled to determine whether a file, directory or "not found"
response needs to be returned and allows metasploit to serve arbitrary
files directly over SMB in addition to files being loaded in runtime
processes calling "LoadLibrary".
