CVE-2020-12005Network attack vector

Unauthenticated service interruption via EDS decompression

Published Jun 15, 2020 · Updated Aug 4, 2024

Resource-exhaustion DoS in Rockwell Automation FactoryTalk Linx 6.00, 6.10, and 6.11 allows remote attackers to interrupt service. Its EDS-upload communication function accepts a rogue EDS.gz file whose bad compression drives decompression until all CPU resources are consumed. No authentication or user interaction is required, and successful exploitation exhausts processor capacity rather than exposing or modifying data.
