# Exploit title: Sysax Multi Server 6.40 ssh component denial of service vulnerability
# Date: 29-8-2015
# Vendor homepage: http://www.sysax.com
# Software Link: http://www.sysax.com/download/sysaxserv_setup.msi
# Version: 6.40
# Author: 3unnym00n
# Details:
# ----------------------------------------------
# byte SSH_MSG_USERAUTH_REQUEST
# string user name
# string service
# string "password"
# boolean FALSE
# Sysax Multi ssh Server doesn't correctly handle SSH_MSG_USERAUTH_REQUEST packet , when the "user name" length malformed can lead dos
# Tested On: win7, xp
# operating steps:
1. install Sysax Multi Server
2. manage server setting > connection protocols confugure > ssh2 based secure shell and sftp/scp on port 22
3. restart the server to let the configuration take effect
4. modify the hostname in this py.
5. running the py, the py will raise exception: sock.recv(block_size) socket.error: [Errno 10054]
netstat -ano , the "22" disappeared.
running the py again, u will see connect failed socket.error: [Errno 10061]
# remark: u can also modify the user auth service request packet, to adjust different user, different password

Proof of Concept
1. Using the default username and password (admin/admin), it is
possible to obtain all credentials used for SMB file transfer. To obtain the
file access http://<printer url>/smb_serverList.csv.
2. The UserName and UserPassword fields are unencrypted and
visible using any text editor.

# byte SSH_MSG_CHANNEL_REQUEST
# uint32 recipient channel
# string "shell"
# boolean want reply
# freeSSHd doesn't correctly handle channel shell request, when the "shell" length malformed can lead crashing
# Tested On: win7, xp
# operating steps:
1. in the freeSSHd settings: add a user, named "root", password is "fuckinA"
2. restart the server to let the configuration take effect
3. modify the hostname in this py.
4. running the py, u will see the server crash
# remark: u can also modify the user auth service request packet, to adjust different user, different password

#For POC -
http://websecgeeks.com/wolf-cms-arbitrary-file-upload-to-command-execution/
1. Description
Every registered users who have access of upload functionality can upload
an Arbitrary File Upload To perform Command Execution
Vulnerable URL
http://targetsite.com/wolfcms/?/admin/plugin/file_manager/browse/
Vulnerable Parameter
"filename"
2. Proof of Concept
A)Login as regular user ( who have access upload functionality )
B)Go to this page -
http://targetsite.com/wolfcms/?/admin/plugin/file_manager/browse/
C)Select upload an file option to upload Arbitary File ( filename ex:
"hello.php" )
D)Now you can access the file by here -
http://targetsite.com/wolfcms/public/hello.php
3. Solution:
Update to version 0.8.3.1

Severity Level:
===============
Medium
Technical Details & Description:
================================
A remote denial of service vulnerability has been discovered in the official Photo Transfer 2 - v1.0 iOS mobile web-application.
The issue allows local attackers to crash or shutdown the software client by usage of special crafted payloads.
The vulnerability is located in the id value restriction of show module path context. Remote attacker can easily crash the application
remotly by including wrong and large id context in integer format. The attack vector is client-side and the request method to provoke
the mobile app crash is GET. The handling of the id path gets confused on negative integer values which results in a permanent app shutdown.
The security risk of the denial of service vulnerability is estimated as medium with a cvss (common vulnerability scoring system) count of 3.4.
Exploitation of the DoS vulnerability requires no privilege application user account or low user interaction. Successful exploitation of the
vulnerability results in an application crash or permanent app service shutdown.
Vulnerable Module(s):
[+] ../show/
Vulnerable Parameter(s):
[+] id
Proof of Concept (PoC):
=======================
The remote denial of service web vulnerability can be exploited by remote attackers without user interaction or privilege web-application user account.
For security demonstration or to reproduce the vulnerability follow the provided information and steps below to continue.

Axigen Mail Server is prone to a directory-traversal vulnerability because it fails to sufficiently sanitize user-supplied data.
A remote attacker could exploit this vulnerability using directory-traversal strings (such as '../') to obtain sensitive information, cause a denial of service condition, or execute arbitrary code with the privileges of the application. This could help the attacker launch further attacks.
