CVE-2019-10775Public exploitNetwork attack vector

Server crash via unencoded redirect header

Published Jan 2, 2020 · Updated Aug 4, 2024

Denial of service in Ecstatic Project ecstatic before 4.1.3 allows remote attackers to crash the server via a crafted URL. The directory-redirect path copied an unencoded form-feed character from the request URL into the HTTP Location header, causing Node.js setHeader to throw a TypeError. A reachable server and an existing directory path are sufficient; no authentication or user interaction is required, and the affected process terminates.
