Pembaruan keamanan Windows baru merusak network printing

September 17, 2021 by Winnie the Pooh

Administrator Windows melaporkan masalah pencetakan (printing) jaringan skala luas setelah menginstal pembaruan keamanan Patch Tuesday September 2021 minggu ini.

Pada hari Selasa, Microsoft merilis enam puluh pembaruan keamanan dan perbaikan untuk banyak bug sebagai bagian dari pembaruan Patch Tuesday bulanan mereka, termasuk perbaikan untuk kerentanan PrintNightmare terakhir yang dilacak sebagai CVE-2021-36958.

Kerentanan ini sangat penting untuk diperbaiki karena digunakan oleh banyak geng ransomware dan pelaku ancaman untuk segera mendapatkan hak istimewa SISTEM pada perangkat yang rentan, seperti yang ditunjukkan di bawah ini.

Namun, banyak administrator sistem Windows sekarang melaporkan bahwa komputer mereka tidak dapat lagi mencetak ke printer jaringan setelah menginstal perbaikan PrintNightmare di server cetak mereka.

Dalam percakapan dengan beberapa admin Windows yang menangani masalah ini, mereka semua memberi tahu BleepingComputer bahwa pembaruan merusak pencetakan jaringan mereka, dan mereka hanya dapat memperbaikinya dengan menghapus pembaruan.

Masalah ini juga tampaknya memengaruhi semua printer jaringan, termasuk HP, Canon, Konica Minolta, dan printer label, serta untuk driver printer Tipe 3 dan Tipe 4. Mereka yang memiliki printer USB yang terhubung langsung ke komputer mereka tidak mengalami masalah apa pun.

Sayangnya, untuk memperbaiki kerentanan PrintNightmare, Microsoft harus membuat perubahan signifikan selama dua bulan terakhir pada fitur Windows Point and Print dan bagaimana driver dapat diinstal dari server print.

Perubahan ini termasuk mewajibkan hak administrator untuk menginstal driver printer melalui fitur Point and Print.

Setelah Microsoft membuat perubahan ini, pengguna Windows mulai menerima kesalahan saat mencoba mencetak, atau Windows akan meminta kata sandi administratif untuk memperbarui driver printer.
