CVE-2019-18629Network attack vector

Arbitrary code execution via signed clone import

Published Mar 4, 2021 · Updated Aug 5, 2024

Code injection in Xerox AltaLink B80xx and C80xx firmware before 101.00X.099.28200 allows attackers to execute an unwanted binary via clone installation. The IP Tables Custom Rules configuration accepts executable content from a manipulated clone DLM instead of rejecting it during installation. Exploitation requires a crafted clone file signed with a compromised private key and results in attacker-supplied code running on the printer.
