CVE-2024-1064Network attack vector

Service interruption via malformed Host header

Published Feb 3, 2024 · Updated Aug 29, 2024

Host header injection in Crafty Controller 4.0.0 through 4.2.2 allows remote attackers to interrupt the service via a crafted Host header. The HTTP handler invokes HTTPHandlerPage.get with an unexpected positional argument, repeatedly raising a TypeError while the process remains running. No authentication or user interaction is required, and the observed result is an unresponsive web interface rather than data access or modification.
