TWiki is a Web-based groupware tool based around the concept of wiki
|
|
pages that can be edited by anybody with a Web browser.

<p>
|
|
The TWiki search function, which uses a shell command executed via the
|
|
Perl backtick operator, does not properly escape shell metacharacters
|
|
in the user-provided search string.
|

<impact type="high">
|
|
<p>
|
|
An attacker can insert malicious commands into a search request,
|
|
allowing the execution of arbitrary commands with the privileges of the
|
|
user running TWiki (usually the Web server user).
|
|
</p>
|

|
<workaround>
|
|
<p>
|
|
There is no known workaround at this time.
|
|
</p>
|
|
</workaround>
|
|
<resolution>
|
|
<p>
|
|
All TWiki users should upgrade to the latest version:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=www-apps/twiki-20040902"</code>
