Pling

Linux Marketplace rentan terhadap serangan RCE dan rantai pasokan

June 24, 2021 by Winnie the Pooh

Peneliti menemukan kerentanan keamanan stored cross-site-scripting (XSS) yang tidak ditambal yang memengaruhi Linux marketplace dan dapat memungkinkan serangan rantai pasokan yang dapat menyebar luas.

Bug tersebut ditemukan mempengaruhi pasar berbasis Pling oleh para peneliti di Positive Security, termasuk AppImage Hub, Gnome-Look, KDE Discover App Store, Pling.com dan XFCE-Look.

Aplikasi PlingStore dipengaruhi oleh kerentanan eksekusi kode jarak jauh (RCE) yang belum ditambal, yang menurut para peneliti dapat dipicu dari situs web mana pun saat aplikasi sedang berjalan – memungkinkan serangan drive-by.

PlingStore adalah penginstal dan aplikasi manajemen konten yang bertindak sebagai etalase digital terkonsolidasi untuk berbagai situs yang menawarkan perangkat lunak dan plugin Linux.

Tim Pling tidak dapat dihubungi, menurut Fabian Bräunlein dengan Positive Security, menulis dalam sebuah posting blog pada hari Selasa – “itulah sebabnya kami memutuskan untuk mempublikasikan kerentanan yang belum ditambal ini untuk memperingatkan pengguna,” katanya.

Bug Stored XSS pertama kali ditemukan mempengaruhi KDE Discover. Stored XSS, juga dikenal sebagai XSS persisten, terjadi ketika skrip berbahaya disuntikkan langsung ke aplikasi web yang rentan. Tidak seperti reflected XSS, serangan stored XSS hanya mengharuskan korban mengunjungi halaman web yang disusupi.

Pada dasarnya, salah satu aset yang dapat diunduh mungkin telah disusupi, jadi pengguna harus diperingatkan bahwa setiap daftar di salah satu pasar yang terpengaruh dapat membajak akun pengguna di platform melalui XSS, kata Bräunlein.
