TITLE:
Softerra Time-Assistant "inc_dir" / "lib_dir" File Inclusion
Vulnerabilities

SECUNIA ADVISORY ID:
SA24729

VERIFY ADVISORY:
http://secunia.com/advisories/24729/

CRITICAL:
Highly critical

IMPACT:
System access

WHERE:
>From remote

SOFTWARE:
Softerra Time-Assistant
http://secunia.com/product/13833/

DESCRIPTION:
M.Hasran Addahroni has reported some vulnerabilities in
Time-Assistant, which can be exploited by malicious people to
compromise a vulnerable system.

Input passed to the "inc_dir" and "lib_dir" parameters in
lib/timesheet.class.php is not properly verified before being used to
include files. This can be exploited to include arbitrary files from
local or external resources.

Successful exploitation requires that "register_globals" is enabled.

The vulnerabilities are reported in Time-Assistant 6.2 Standard and
Enterprise, and Time-Assistant Light. Other versions may also be
affected.

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

Set "register_globals" to "Off".
