CVE-2024-7957Network attack vector

Arbitrary file overwrite via unsanitized realm name

Published Mar 20, 2025 · Updated Mar 20, 2025

Path traversal in the Onyx Zulip connector affects the latest version and allows remote attackers to overwrite server files. ZulipConnector.load_credentials joins an unvalidated realm_name to the system temporary directory and writes attacker-supplied zuliprc_content to that path. Exploitation requires a matching zuliprc- directory in the temporary directory and can create or replace files writable by the service account.
