Details

It was discovered that MoinMoin did not properly sanitize its input when
processing AnyWikiDraw and TWikiDraw actions. A remote attacker with write
access could exploit this to overwrite arbitrary files and execute
arbitrary code with the priviliges of the web server (user 'www-data').

It was discovered that MoinMoin also did not properly sanitize its input
when processing the AttachFile action. A remote attacker could exploit
this to overwrite files via directory traversal.
