Synopsis ========
A bug in the TWiki search function allows an attacker to execute arbitrary commands with the permissions of the user running TWiki.
Background ==========
TWiki is a Web-based groupware tool based around the concept of wiki pages that can be edited by anybody with a Web browser.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 www-apps/twiki < 20040902 >= 20040902
Description ===========
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 ======
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).
Workaround ==========
There is no known workaround at this time.
Resolution ==========
All TWiki users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=www-apps/twiki-20040902"
