CVE-2019-18905Network attack vector

Image tampering via unchecked repository-key import

Published Apr 3, 2020 · Updated Sep 17, 2024

Insufficient data-authenticity verification in SUSE Linux Enterprise Server AutoYaST allows remote attackers to tamper with created images. Deprecated image-creation code passes --gpg-auto-import-keys to zypper, automatically trusting repository signing keys received through an intercepted connection. Exploitation requires the deprecated image workflow and a man-in-the-middle position, allowing attacker-controlled packages to enter the generated image.
