Description:

The remote host is affected by the vulnerability described in GLSA-200411-33
(TWiki: Arbitrary command execution)


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.

Solution:
All TWiki users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=www-apps/twiki-20040902"


Risk factor : High
