    Allocation of Resources Without Limits or Throttling

    tornado is a Python web framework and asynchronous networking library, originally developed at FriendFeed.

    Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling through the multipart/form-data parser. An attacker can generate an extremely high volume of logs, leading to a denial of service by sending malformed multipart form data that triggers continuous error logging.

    Note:

    This is only exploitable if the logging subsystem is synchronous.

    How to fix Allocation of Resources Without Limits or Throttling?

    Upgrade tornado to version 6.5 or higher.

    Regular Expression Denial of Service (ReDoS)

    tornado is a Python web framework and asynchronous networking library, originally developed at FriendFeed.

    Affected versions of this package are vulnerable to Regular Expression Denial of Service (ReDoS) due to inefficient cookie parsing that results in quadratic performance. An attacker could cause tornado to consume excessive CPU resources and block the event loop through maliciously crafted cookies.

    How to fix Regular Expression Denial of Service (ReDoS)?

    Upgrade tornado to version 6.4.2 or higher.

    HTTP Request Smuggling

    tornado is a Python web framework and asynchronous networking library, originally developed at FriendFeed.

    Affected versions of this package are vulnerable to HTTP Request Smuggling due to the handling of multiple Transfer-Encoding: chunked headers. An attacker can desynchronize the connection and potentially bypass ACLs or poison caches by sending crafted requests with duplicate Transfer-Encoding: chunked headers.

    How to fix HTTP Request Smuggling?

    Upgrade tornado to version 6.4.1 or higher.

    Improper Neutralization of CRLF Sequences ('CRLF Injection')

    tornado is a Python web framework and asynchronous networking library, originally developed at FriendFeed.

    Affected versions of this package are vulnerable to Improper Neutralization of CRLF Sequences ('CRLF Injection') through the CurlAsyncHTTPClient headers. An attacker can manipulate HTTP headers and construct unauthorized requests by injecting CRLF sequences into header values.

    How to fix Improper Neutralization of CRLF Sequences ('CRLF Injection')?

    Upgrade tornado to version 6.4.1 or higher.
