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

| <description> |
| <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> |
| <p> |
| All TWiki users should upgrade to the latest version: |
| </p> |
| <code> |
| # emerge --sync |
| # emerge --ask --oneshot --verbose ">=www-apps/twiki-20040902"</code> |
| </resolution> |
