Description: Several vulnerabilities were reported in OTRS. A remote user can inject SQL commands and conduct cross-site scripting attacks.
The software does not properly validate user-supplied input. A remote user can supply specially crafted parameter values to execute
SQL commands on the underlying database. The 'User' parameter in the 'Login' function is affected. The 'TicketID' and 'ArticleID'
parameters in the 'AgentTicketPlain' function are also affected.
Some demonstration exploit URLs are provided:
[OTRS_BaseURI]/index.pl?Action=Login&User=%27[SQL_HER
E]
[OTRS_BaseURI]/admin/index.pl?Action=AgentTicketPlain&ArticleID=1&TicketID=1%20[SQL_HERE]
[OTRS_BaseURI]/admin/index.pl?Action=AgentTicketPlain&TicketID=1&Articl
eID=1%20[SQL_HERE]
Several scripts do not properly filter HTML code from user-supplied input before displaying the input. A
remote user can create a specially crafted HTML e-mail that, when processed by a target queue moderator user via the attachment
download button, will cause arbitrary scripting code to be executed by the target user's browser. The code will originate from
the site running the OTRS software and will run in the security context of that site. As a result, the code will be able to access
the target user's cookies (including authentication cookies), if any, associated with the site, access data recently submitted by
the target user via web form to the site, or take actions on the site acting as the target user.
The 'QueueID' and 'Action' parameters
are not properly filtered. A remote user can create a specially crafted URL that, when loaded by a target authenticated user, will
cause arbitrary scripting code to be executed by the target user's browser.
Some demonstration exploit URLs are provided:
[OTRS_BaseURI]/index.pl?QueueID=%22%3E%3Cs
cript%3Ealert('[XSS_HERE]')%3B%3C/script%3E%3Cx%20y=%22
[OTRS_BaseURI]/index.pl?Action="><script>alert(document.title);</script><x%20"

vendor credits Moritz Naumann (Naumann IT Consulting & Services) with discovering these vulnerabilities.
