TITLE:
Limbo Multiple Vulnerabilities

SECUNIA ADVISORY ID:
SA21944

VERIFY ADVISORY:
http://secunia.com/advisories/21944/

CRITICAL:
Highly critical

IMPACT:
System access

WHERE:
>From remote

SOFTWARE:
Limbo 1.x
http://secunia.com/product/4445/

DESCRIPTION:
HACKERS PAL has discovered some vulnerabilities in Limbo, which can
be exploited by malicious people to compromise a vulnerable system.

1) Input passed to the "classes_dir" parameter in
classes/adodbt/sql.php isn't properly verified, before it is used to
include files. This can be exploited to include arbitrary files from
external and local resources.

Successful exploitation requires that "register_globals" is enabled.

2) Input passed to the "lm_absolute_path" and "install_dir"
parameters in admin/components/com_fm/fm.install.php and
components/com_fm/fm.install.php isn't properly verified before being
used to delete or copy files. This can be exploited to delete
arbitrary files or manipulate the content of the fm.english.php PHP
script.

Successful exploitation allows execution of arbitrary PHP code, but
requires that "register_globals" is enabled.

It has also been reported that it is possible to create directories
and empty files, and disclose the full path to certain scripts.

The vulnerabilities have been confirmed in version 1.0.4.2. Other
versions may also be affected.

SOLUTION:
Edit the source code to ensure that input is properly verified.

Set "register_globals" to "Off".
