| "MG-SOFT Net Inspector is a powerful fault management application with alarming subsystem that complies with the international alarm reporting recommendations (ITU X.733). The software lets you effectively monitor the status of network devices and manage alarms associated with devices in the supervised TCP/IP network." Multiple vulnerabilities have been discovered in MG-SOFT Net Inspector, these vulnerabilities allow attackers to crash the system, as well as cause it potentially execute arbitrary code. |

Vulnerable systems:
* MG-SOFT Net Inspector version 6.5.0.828
Format string in mghttpd:
mghttpd is a simple HTTP daemon running on port 5228 used to allow the clients to download the Net Inspector Java Client. This server is affected by a format string vulnerability located in the function which logs the clients requests in the log file.
Directory traversal in mghttpd:
This service is also affected by a classical directory traversal vulnerability using both the slash and backslash plain delimiters which can be exploited to download files from the disk on which is located the server.
Crash in MgWTrap3:
The SNMP Trap Service other than binding the local TCP port 8888 and the UDP 162 for collecting SNMP queries, binds also an additional UDP port which changes each time the service is executed (uses the first free available port).
Sending a packet (empty or with any desired content since it's not important) directly to this port raises an exception which terminates the service immediately.
This service is the core of almost all the MG-SOFT products which so result all vulnerable.
Denial of Service in niengine:
The Net Inspector Fault Management server (niengine) can be easily freezed with CPU at 100% and full memory consumption through a malformed packet.
Exploits:
Format string in mghttpd
GET /%n%n%s%s%n%n%n%s HTTP/1.0
Directory traversal in mghttpd
GET ../../../../boot.ini HTTP/1.0
GET \../..\../..\windows/win.ini HTTP/1.0
Crash in MgWTrap3
echo|nc SERVER PORT -v -v -u
Denial of Service in niengine
echo -n -e \x2a\x45\x67\xf2\x00\x00\x00\x00|nc SERVER 5221 -v -v -w 1
