CVE: CVE-2010-0438
- --------------------------------------------------------------------------------
This Advisory covers a vulnerability discovered in the OTRS core system.
SQL Injection
Missing security quoting for SQL statements allows agents and customers to
manipulate SQL queries. So it's possible for authenticated users to inject
SQL queries via string manipulation of statements.
A malicious user may be able to manipulate SQL queries to read or modify
records in the database. This way it could also be possible to get access
to more permissions (e. g. administrator permissions).
To use this vulnerability the malicious user needs to have a valid Agent-
or Customer-session.
Affected by this vulnerability are all releases of OTRS 2.1.x up
to and including 2.4.6.
This vulnerability is fixed in OTRS 2.1.9, OTRS 2.2.9, OTRS 2.3.5
and OTRS 2.4.7.
Fixed OTRS releases can be found at:
o http://otrs.org/releases/
As a workaround it's also possible to replace the file
Kernel/System/Ticket.pm by a version that has been fixed.
o OTRS 2.1.x: v1.233.2.3
o OTRS 2.2.x: v1.275.2.19
o OTRS 2.3.x: v1.346.2.9
o OTRS 2.4.x: v1.416.2.10
(http://source.otrs.org/viewvc.cgi/otrs/Kernel/System/Ticket.pm?view=log).
