Vulnerability overview/description:
Voxlog professional suffers from multiple critical vulnerabilities. The
flaws have been confirmed at two independent installations. As only a
very short test has been performed, many more flaws are to be expected:

1) Unauthenticated file disclosure vulnerability
The "get.php" functionality of the web interface of voxlog professional
allows an attacker to read arbitrary files from the operating system,
such as config files or other sensitive voxlog files and voice

A valid web interface user account is _not_ necessary to exploit this

2) Unauthenticated SQL injection & command execution
The web interface suffers from multiple SQL injection flaws, e.g. in
As the voxlog professional installations use Microsoft SQL server with
"sa" account, command execution through the "xp_cmdshell" stored
procedure is possible.

An attacker gains access to all stored sensitive voice recordings
and is able to take over the whole OS with "SYSTEM" rights.

A valid web interface user account is _not_ necessary to exploit this

3) Weak default accounts for OS and web interface
Two independent installations have been tested and the same standard
user accounts were found.

The operating system, where voxlog professional comes preinstalled,
has three different accounts with very weak passwords, at least one
of them with local administrative rights.

The web interface has a default administrator account with a very weak

An attacker gains access to all stored sensitive voice recordings
through either that web interface or the OS accounts and is able
to take over the whole OS with admin rights.

Proof of concept:
1) File disclosure, retrieve C:\boot.ini

Voxlog also uses a "session" and "user" parameter (besides the "file"
parameter) base64-encoded within the "v" parameter for "GET.PHP",
but those values are not checked and can be removed for exploitation.

2) SQL injection
waitfor delay '0:0:5' --+
exec master..xp_cmdshell 'xxxxx' --+

3) Default user accounts, usernames:
OS: voxctadmin, voxctsystem, voxctuser
Web interface: admin, user

Vulnerable / tested versions:
voxlog professional v3.7.2.729 (version of webclient)
voxlog professional v3.7.0.633 (version of webclient)

It is assumed that older or also newer versions are affected. Further
version numbers couldn't be verified.

Vendor contact timeline:
2011-02-03: Contacting vendor through office@voxtronic.com, asking for
security contact, attaching responsible disclosure policy
2011-02-11: Sent another email as no one replied. Proposing public
disclosure date
2011-02-12: Vendor replied
2011-02-14: Sending security advisory to given contact
2011-02-15: Vendor reply: checking vulnerabilities in latest version
2011-03-18: Meeting
2011-04-21: Contacting via telephone again
2012-02-20: Release of advisory as vendor is not responsive

Customers of Voxlog should contact the vendor regarding security
patches as they are not publicly available.

Restrict access to the whole server as much as possible. Only allow
trusted IP addresses and users in order to minimise attack surface.

Change the default accounts immediately and implement a strict
password policy.
