Vulnerability Details : CVE-2011-1567 (1 public exploit)

Multiple stack-based buffer overflows in IGSSdataServer.exe 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.

- Metasploit Modules Related To CVE-2011-1567

7-Technologies IGSS IGSSdataServer.exe Stack Buffer Overflow
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.

7-Technologies IGSS 9 IGSSdataServer .RMS Rename Buffer Overflow
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.
