CVE-2023-28370
Open redirect vulnerability in Tornado versions 6.3.1 and earlier allows a remote unauthenticated attacker to redirect a user to an arbitrary web site and conduct a phishing attack by having user access a specially crafted URL.
GHSA-qppv-j76h-2rpx
Summary
Tornado interprets
-
,+
, and_
in chunk length andContent-Length
values, which are not allowed by the HTTP RFCs. This can result in request smuggling when Tornado is deployed behind certain proxies that interpret those non-standard characters differently. This is known to apply to older versions of haproxy, although the current release is not affected.Details
Tornado uses the
int
constructor to parse the values ofContent-Length
headers and chunk lengths in the following locations:tornado/http1connection.py:445
tornado/http1connection.py:621
tornado/http1connection.py:671
Because
int("0_0") == int("+0") == int("-0") == int("0")
, using theint
constructor to parse and validate strings that should contain only ASCII digits is not a good strategy.Release Notes
