[原文]The File Check Utility (fcheck.exe) in ASG-Sentry Network Manager 7.0.0 and earlier allows remote attackers to cause a denial of service (CPU consumption) or overwrite arbitrary files via a query string that specifies the -b option, probably due to an argument injection vulnerability.


[CNNVD]ASG-Sentry Network Manager 拒绝服务攻击漏洞(CNNVD-200803-217)

        ASG-Sentry Network Manager 7.0.0 及其早期版本中的File Check Utility (fcheck.exe)远程攻击者通过一个详细说明-b 选择的查询字符串,来造成一个拒绝服务(CPU消耗)或写满任意文件。该问题可能源于一个变量注入漏洞。

===============
1) Introduction
===============


>From vendor's website:
"The ASG-Sentry family of products is a suite of tools strategically
engineered to control, monitor, manage, and enhance your network.
Sentry's tools provide you with full visibility to your network from
any Web browser. Sentry also allows you to fully instrument your
company's applications, CPUs, disk space, memory, files, Windows and
UNIX platforms, and more."

=======
2) Bugs
=======

---------------------------
A] arbitrary files deleting
---------------------------

The fcheck.exe (File Check Utility) CGI available in ASG is used for
handling some index files which contain a list of filenames and
checksums.

The -b option of this utility allows the creation of these index files
and is possible to specify both the name of the output file and,
optionally, the folder which will be scanned recursively for finding
and reading the various files to add to the list.

The first vulnerability is in the possibility for an external attacker
to use this CGI for overwriting existent files with no data (specifying
a new folder which will be created by the same program) or with the
list of filenames described before.
Naturally is possible to specify both files on the local disks or on
network shares.

The second effect instead is the possibility of occupying CPU and disk
for the scanning of any file in the disk simply specyfing, for example,
c:\ as folder.


---------------------------
B] heap-overflow in FxAgent
---------------------------

The FxAgent process running on UDP port 6161 is used for handling the
various SNMP requests.
A community field longer than 64 bytes can be used by an attacker to
exploit a heap-overflow.


--------------------------
C] termination of FxIAList
--------------------------

FxIAList is a service which runs on the TCP port 6162 and is used for
the logging operations which include the commands "exit", "trace on"
"verbose", "trace off" and the name of the log file to create
(xxxx.xx.xx) and its content.
The main problem is that the server doesn't require authentication so
anyone can send the "exit" command and the service will just terminate.


------------------------------
D] buffer-overflow in FxIAList
------------------------------

The same service described before is affected also by a stack based
buffer-overflow which happens during the copying of the data we want
to write to the log file (max 1023 bytes) in a buffer of only 500.

3) The Code
===========


http://aluigi.org/poc/asgulo.zip
http://exploit-db.com/sploits/2008-asgulo.zip

A]
  http://SERVER:6161/snmx-cgi/fcheck.exe?-b+..\../..\boot.ini
  http://SERVER:6161/snmx-cgi/fcheck.exe?-b+c:\windows\win.ini
  http://SERVER:6161/snmx-cgi/fcheck.exe?-b+c:\file.txt+c:\
  http://SERVER:6161/snmx-cgi/fcheck.exe?-b+\host\document.txt
    this link for the network share is correct because Apache converts
    any backslash to double so that one becomes \\host\\document.txt

B]
  nc SERVER 6161 -v -v -u < asgulo_fxagent.txt

C]
  nc SERVER 6162 -v -v -w 1 < asgulo-ialist1.txt

D]
  nc SERVER 6162 -v -v -w 1 < asgulo-ialist2.txt
