ID: OSA-2005-01
Date: 2005-11-22
Title: Vulnerabilities in OTRS-Core allows
SQL-Injection and Cross-Site-Scripting
Severity: Critical

URL: http://otrs.org/advisory/OSA-2005-01-en/
-----------------------------------------------------------------------
This Advisory covers three vulnerabilities in the OTRS-System-Core.
SQL-Injection via UNION
Missing security quoting for SQL statements allows agents the
manipulation of SQL queries. So it's possible to inject SQL queries
via UNION statements.
A malicious user may be able to login successfully without valid
credentials. Authentication mechanisms other than the database
backend authentication are not affected.
Authenticated users can use this vulnerabilitiy to get records from
other OTRS database tables. This informations can be used for
other attacks like session hijacking.
Open attachment in new browser window
In default config setting OTRS opens attachments in new browser
windows if an agent clicks on the download symbole.
An attacker can exploit this vulnerabilitiy by sending manipulated
attachments with active script content which will be executed by
the browser with user privileges.
Input fields allows injection of script code
Missing HTML quoting allows an agent in a valid session the
injection of HTML tags.
This vulnerability allows an attacker to inject script code
into the OTRS webinterface which will be loaded and executed
in users browsers.
Affected by these vulnerabilities are all releases of OTRS 2.x up
to and including 2.0.3 and all releases of OTRS 1.x up to and
including 1.3.2.
These vulnerabilities are fixed in OTRS 2.0.4 and OTRS 1.3.3.
Fixed OTRS releases can be found at:
o ftp://ftp.otrs.org/
As a workaround for vulnerability #2 it's possible to disable the
'open attachments in a browser window' feature by changing the
config setting "AttachmentDownloadType = attachment".
