CVE-2021-22890

CVE-2021-22890 affects curl 7.63.0 through 7.75.0. When using TLS 1.3 with an HTTPS proxy, libcurl could confuse TLS session tickets from the proxy as if they came from the remote server, potentially causing the host’s session ticket to be resumed incorrectly and bypass server certificate checks,...

Ubuntu 16.04 LTS / 18.04 LTS / 20.04 LTS : curl vulnerabilities (USN-4898-1)

The remote Ubuntu 16.04 LTS / 18.04 LTS / 20.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-4898-1 advisory. Viktor Szakats discovered that curl did not strip off user credentials from referrer header fields. A remote attacker could...

CVE-2021-22890

A flaw was found in the way libcurl handled TLS 1.3 session tickets. A malicious HTTPS proxy could possibly use this flaw to make libcurl resume a TLS session it previously had with the proxy while intending to resume a TLS session with a target server, making it possible for the proxy to perform...

TLS 1.3 session ticket proxy host mix-up

Enabled by default, libcurl supports the use of TLS 1.3 session tickets to resume previous TLS sessions to speed up subsequent TLS handshakes. When using an HTTPS proxy and TLS 1.3, libcurl can confuse session tickets arriving from the HTTPS proxy but work as if they arrived from the remote serve...

Name of the Vulnerable Software and Affected Versions: curl versions 7.63.0 through 7.75.0 Description: The issue is related to the incorrect handling of TLS 1.3 session tickets, which can allow a malicious HTTPS proxy to perform a man-in-the-middle MITM attack. When using an HTTPS proxy and TLS...

GnuTLS 3.6.x before 3.6.14 uses incorrect cryptography for encrypting a session ticket (a loss of confidentiality in TLS 1.2 and an authentication bypass in TLS 1.3). The earliest affected version is 3.6.4 (2018-09-24) because of an error in a 2018-09-18 commit. Until the first key rotation the TLS server always uses wrong data in place of an encryption key derived from an application.
