twiki -- arbitrary shell command execution


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.
