FreeBSD : twiki -- arbitrary shell command execution (b4af3ede-36e9-11d9-a9e7-0001020eed82)

This script is Copyright (C) 2009-2013 Tenable Network Security, Inc.


Synopsis :

The remote FreeBSD host is missing a security-related update.

Description :

Hans Ulrich Niedermann reports :

The TWiki search function uses a user-supplied search string to
compose a command line executed by the Perl backtick (``) operator.

The search string is not checked properly for shell metacharacters and
is thus vulnerable to search string containing quotes and shell
commands.

IMPACT: An attacker is able to execute arbitrary shell commands with
the privileges of the TWiki process.
