PySCTChecker

PySCTChecker 설명 도메인이 인증서 투명성Certificate Transparency을 제대로 구현하고 있는지 확인하기 위한 빠르고 간단한 Python 스크립트입니다. 구현되어 있다면 서버 측에서 인증서 투명성이 어떻게 구현되었는지 관찰할 수 있습니다. 서버가 인증서 투명성을 구현할 때, 적어도 하나의 SCT서버 TLS 인증서가 투명성 로그에 포함되었다는 증명를 제공해야 합니다. SCT는 인증서에 포함, TLS 확장, OCSP Stapling의 세 가지 방식으로 제공될 수 있습니다. PySCTChecker를 사용하면...

openssl: Double-free When Checking OCSP Stapled Response

A flaw was found in OpenSSL. A malicious server can exploit the TLS Online Certificate Status Protocol OCSP stapling feature by sending a specially crafted response. This can trigger a double-free vulnerability in the client's certificate verification process, potentially leading to a Denial of...

Astra Linux – Vulnerability in curl

When curl is instructed to use the Certificate Status Request TLS extension, also known as OCSP stapling, to verify that the server certificate is valid, it may fail to detect certain OCSP issues and instead incorrectly consider the response to be fine. If the returned status reports an error oth...
