<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.
</p>
</description>
<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>
</impact>
<workaround>
<p>
There is no known workaround at this time.
</p>
</workaround>
<resolution>

<code>
# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=www-apps/twiki-20040902&quot;</code>
