COMPLETE Summary
Multiple stack-based buffer overflows in IGSSdataServer.exe 9.00.00.11063 and earlier in 7-Technologies Interactive Graphical SCADA System (IGSS) allow remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via crafted (1) ListAll, (2) Write File, (3) ReadFile, (4) Delete, (5) RenameFile, and (6) FileInfo commands in an 0xd opcode; (7) the Add, (8) ReadFile, (9) Write File, (10) Rename, (11) Delete, and (12) Add commands in an RMS report templates (0x7) opcode; and (13) 0x4 command in an STDREP request (0x8) opcode to TCP port 12401.
Common Weakness Enumeration (CWE)
Common Attack Pattern Enumeration and Classification (CAPEC)
- Buffer Overflow via Environment Variables This attack pattern involves causing a buffer overflow through manipulation of environment variables. Once the attacker finds that they can modify an environment variable, they may try to overflow associated buffers. This attack leverages implicit trust often placed in environment variables.
- Overflow Buffers Buffer Overflow attacks target improper or missing bounds checking on buffer operations, typically triggered by input injected by an attacker. As a consequence, an attacker is able to write past the boundaries of allocated buffer regions in memory, causing a program crash or potentially redirection of execution as per the attackers' choice.
- Client-side Injection-induced Buffer Overflow This type of attack exploits a buffer overflow vulnerability in targeted client software through injection of malicious content from a custom-built hostile service.
- Filter Failure through Buffer Overflow In this attack, the idea is to cause an active filter to fail by causing an oversized transaction. An attacker may try to feed overly long input strings to the program in an attempt to overwhelm the filter (by causing a buffer overflow) and hoping that the filter does not fail securely (i.e. the user input is let into the system unfiltered).
- MIME Conversion An attacker exploits a weakness in the MIME conversion routine to cause a buffer overflow and gain control over the mail server machine. The MIME system is designed to allow various different information formats to be interpreted and sent via e-mail. Attack points exist when data are converted to MIME compatible format and back.

Metasploit
description This module exploits a vulnerability found on 7-Technologies IGSS 9. By supplying a long string of data to the 'Rename' (0x02), 'Delete' (0x03), or 'Add' (0x04) command, a buffer overflow condition occurs in IGSSdataServer.exe while handing an RMS report, which results arbitrary code execution under the context of the user. The attack is carried out in three stages. The first stage sends the final payload to IGSSdataServer.exe, which will remain in memory. The second stage sends the Add command so the process can find a valid ID for the Rename command. The last stage then triggers the vulnerability with the Rename command, and uses an egghunter to search for the shellcode that we sent in stage 1. The use of egghunter appears to be necessary due to the small buffer size, which cannot even contain our ROP chain and the final payload. id MSF:EXPLOIT/WINDOWS/SCADA/IGSS9_IGSSDATASERVER_RENAME last seen 2020-06-07 modified 2017-07-24 published 2011-06-09 references reporter Rapid7 source https://github.com/rapid7/metasploit-framework/blob/master//modules/exploits/windows/scada/igss9_igssdataserver_rename.rb title 7-Technologies IGSS 9 IGSSdataServer .RMS Rename Buffer Overflow description This module exploits a vulnerability in the igssdataserver.exe component of 7-Technologies IGSS up to version 9.00.00 b11063. While processing a ListAll command, the application fails to do proper bounds checking before copying data into a small buffer on the stack. This causes a buffer overflow and allows to overwrite a structured exception handling record on the stack, allowing for unauthenticated remote code execution. Also, after the payload exits, IGSSdataServer.exe should automatically recover. id MSF:EXPLOIT/WINDOWS/SCADA/IGSS9_IGSSDATASERVER_LISTALL last seen 2020-06-04 modified 2017-07-24 published 2011-05-16 references reporter Rapid7 source https://github.com/rapid7/metasploit-framework/blob/master//modules/exploits/windows/scada/igss9_igssdataserver_listall.rb title 7-Technologies IGSS IGSSdataServer.exe Stack Buffer Overflow
