TITLE:
Zomplog File Upload Two Vulnerabilities

SECUNIA ADVISORY ID:
SA27028

VERIFY ADVISORY:
http://secunia.com/advisories/27028/

CRITICAL:
Highly critical

IMPACT:
System access, Security Bypass

WHERE:
>From remote

SOFTWARE:
Zomplog 3.x
http://secunia.com/product/5963/

DESCRIPTION:
InATeam has discovered two vulnerabilities in Zomplog, which can be
exploited by malicious people to bypass certain security restrictions
and to compromise a vulnerable system.

1) An error exists in the file upload functionality due to
admin/upload_files.php not checking file extensions properly. This
can be exploited to upload files with arbitrary extensions (e.g.
".php") and execute arbitrary PHP code on the server.

2) The problem is that admin/upload_files.php does not properly check
for authentication. This can be exploited to access the file upload
functionality by accessing the script directly.

The vulnerabilities are confirmed in version 3.8.1. Other versions
may also be affected.

SOLUTION:
Restrict access to admin/upload_files.php (e.g. with a ".htaccess"
file).
