CVSS: 7.5EPSS: 0%CPEs: 1EXPL: 0CVE-2025-47287 – Tornado vulnerable to excessive logging caused by malformed multipart form data
https://notcve.org/view.php?id=CVE-2025-47287
15 May 2025 — Tornado is a Python web framework and asynchronous networking library. When Tornado's ``multipart/form-data`` parser encounters certain errors, it logs a warning but continues trying to parse the remainder of the data. This allows remote attackers to generate an extremely high volume of logs, constituting a DoS attack. This DoS is compounded by the fact that the logging subsystem is synchronous. All versions of Tornado prior to 6.5.0 are affected. • https://github.com/tornadoweb/tornado/commit/b39b892bf78fe8fea01dd45199aa88307e7162f3 • CWE-770: Allocation of Resources Without Limits or Throttling •
CVSS: 7.8EPSS: 0%CPEs: 1EXPL: 0CVE-2024-52804 – Tornado has HTTP cookie parsing DoS vulnerability
https://notcve.org/view.php?id=CVE-2024-52804
22 Nov 2024 — Tornado is a Python web framework and asynchronous networking library. The algorithm used for parsing HTTP cookies in Tornado versions prior to 6.4.2 sometimes has quadratic complexity, leading to excessive CPU consumption when parsing maliciously-crafted cookie headers. This parsing occurs in the event loop thread and may block the processing of other requests. Version 6.4.2 fixes the issue. A flaw was found in Tornado's HTTP cookie parsing algorithm. • https://github.com/advisories/GHSA-7pwv-g7hj-39pr • CWE-400: Uncontrolled Resource Consumption CWE-770: Allocation of Resources Without Limits or Throttling •

24 Jan 2020 — Tornado before 3.2.2 sends arbitrary responses that contain a fixed CSRF token and may be sent with HTTP compression, which makes it easier for remote attackers to conduct a BREACH attack and determine this token via a series of crafted requests.
