Multiple MetaDot Vulnerabilities
|
January 12, 2022
|
| Vendor |
: Metadot Corporation |
| URL |
:
http://www.metadot.com
|
| Version |
: MetaDot Portal 5.6.5.4b5 && Earlier [ All Versions ] |
| Risk |
: Multiple Vulnerabilities |
Description:
Metadot is a popular open source portal software (GPL) recognized for its revolutionary
ease-of-use. It provides content management like file, page and link management, collaboration
features like discussion forums and polls and personalization like My Yahoo. It is powered by
Perl && MySQL. Users range from home users to government, banks, universities and even NASA ;)

SQL Injection Vulnerability:
It may be possible for an attacker to influence SQL queries by passing unexpected data to
certain variables including the "id" and "key" variable. Even if an attacker is not successful
with influencing an SQL query he can cause the outputted error message to execute script into
an unsuspecting users browser thus causing a Cross Site Scripting attack. Also, the SQL error
messages reveal a great deal of data about the server. Below is an example error message. The
URI used to create this error was index.pl?isa=Session&op;=auto_login&new;_user=&key;='[Problem]
--[ Begin Error Message ]--------------------------------------------------------------------

::handler('Apache=SCALAR(0xb421470)') called at /dev/null line 0 eval {...} called at /dev/null line 0
---------------------------------------------------------------------------------------------
Below are some examples URI's that will allow an attacker to influence queries, gather info or XSS.
/index.pl?id=[Evil_Query]
/index.pl?iid=[Evil_Query]
/index.pl?isa=Session&op;=auto_login&new;_user=&key;=[Evil_Query]
|
Information Disclosure && Path Disclosure:
There is a great deal of information given up by interrupting the SQL query, but can also be caused
in other ways than the previously mentioned. Lets look at /index.pl?iid=[ValidID]&isa;=Discussion&op;=
Where [ValidID] is should be a valid id number such as 1000 or whatever it may be.
--[ Begin Error Message ]--------------------------------------------------------------------
Software error:
must provide operation name at /home/sharem/metadot/metadot/Auditable.pm line 196
Auditable::is_allowed_to_do('Discussion=HASH(0xae19218)', '', 'Metadot::User::FlexUser=HASH(0xb414f70)', 1)

Apache::Registry::handler('Apache=SCALAR(0xacf893c)') called at /dev/null line 0
eval {...} called at /dev/null line 0
---------------------------------------------------------------------------------------------
As you can see that will give you the server path, perl version and several other interesting bits of
information. Path can also be disclosed by a bogus value in the "isa" variable. /index.pl?isa=blah

Cross Site Scripting:
Cross Site Scripting:
There are a number of potential cross site scripting issues in MetaDot. Below are some examples
/index.pl?isa=XSS<iframe%20src=http://www.gulftech.org>
/userchannel.pl?id=435&isa;=NewsChannel&redirect;=1&op;="><iframe>
/index.pl?iid='"><iframe%20src=http://www.gulftech.org>
|

The MetaDot team have addressed this issue and an update was supposed to be released on Thursday the
8th of January. Users of the MetaDot portal system are encouraged to upgrade immediately. Users can
