I. BACKGROUND
MapInfo Discovery is an enterprise browser-driven map catalog and map
viewer application. It functions as an extension to MapInfo
Professional®.
II. DESCRIPTION
Multiple vulnerabilities have been found in MapInfo Discovery which
allow remote attackers to gain administrative access to MapInfo
Discovery, obtain database credentials, and execute arbitrary scripting
code.
***** ISSUE 1: Information Disclosure *****
Insecure storage of log files can lead to confidential information being
disclosed.
http://<hostname>/midiscovery
/ErrLog/mi3errors.log
***** ISSUE 2: Cross-site Scripting *****
Failure to filter scripting characters in the mapID value passed to
Mapfram.asp can lead to execution of arbitrary scripting code.
MapFrame.asp?mapID=5&mapname=<script>
***** ISSUE 3: Cleartext Passwords *****
MapInfo Discovery passes login credentials and SQL database credentials
to forms in plaintext. Remote attackers can use a network sniffer to
recover credentials to both MapInfo Discovery and the SQL database
associated with it.
http://<hostname>/midiscovery/as
plib/SignIn.asp passes login credentials
in plaintext.
Database Credentials
<INPUT TYPE="text" size="30" maxlength="50" NAME="DatabaseName" Value="MIDiscovery" >
<INPUT TYPE="text" size="30" maxlength="50" NAME="DatabaseServerName" Value="10.0.0.2" >
<INPUT TYPE="text" size="30" maxlength="70" NAME="DatabaseUserName" Value="midiscovery" >
<INPUT TYPE="password" size="21" maxlength="20" NAME="DatabaseUserPassword1" Value="lirumisu69" >
<INPUT TYPE="password" size="21" maxlength="20" NAME="DatabaseUserPassword2" Value="lirumisu69" >
***** ISSUE 4: Administrative Login Bypass *****
MapInfo Discovery does not store session information securely.
Authentication is simply tracked by checking the value of a variable
passed in the URL. Attackers can bypass this check by changing the value
and gain access to administrative pages.
Only the value of 'ps' is checked to authenticate administrative users.

//<hostname>/midiscovery/asplib/MapPassword.asp?id=140&ps=0&
amp;Wrong=1
III. ANALYSIS
Any remote attacker with access to a server running MapInfo Discovery
can exploit the above-described vulnerabilities. Successful exploitation
could lead to administrative access and compromise of the SQL database.
IV. DETECTION
MapInfo Discovery 1.0 and 1.1 for Windows are known to be vulnerable.
V. CVE INFORMATION
