PassTheCert

PassTheCert Sometimes, Domain Controllers do not support PKINIT. This can be because their certificates do not have the Smart Card Logon EKU. However, several protocols, including LDAP, support Schannel, thus authentication through TLS. We created a small Proof-of-Concept tool that allows...

Curl 8.21.0 < 8.23.0 Multiple Connection Reuse Vulnerabilities

The version of curl installed on the remote host is 8.21.0 prior to 8.23.0. It is, therefore, affected by multiple connection reuse vulnerabilities: - libcurl's connection cache match function never considers the automatic client certificate option, so a cached, already authenticated Schannel...

curl: CVE-2026-115529: Schannel TLS auto client session resumption

Summary: In curl 8.23.0 with Schannel, TLS session resumption preserves an authenticated client certificate identity across a cross-origin redirect even after automatic client certificate selection is disabled. This appears to be an incomplete fix for CVE-2026-86415, where the original fix...

CVE-2026-86415

A vulnerability in libcurl (specifically versions prior to 8.23.0) allows a cached, already authenticated Schannel connection to be reused for a transfer redirected to a different origin. The root cause is that the connection cache match function fails to account for the automatic client certific...
