FAUCET Score

CVE-2015-0205 describes a vulnerability in OpenSSL versions 1.0.0 before 1.0.0p and 1.0.1 before 1.0.1k, where the ssl3_get_cert_verify function incorrectly handles client authentication with Diffie-Hellman (DH) certificates. This flaw allows remote attackers to bypass authentication and gain unauthorized access to a server configured to recognize a DH-supporting Certification Authority, without needing the private key. The vulnerability has a CVSS score of 5.0 (Medium), indicating a network attack vector with low complexity and a partial integrity impact. There is no evidence of active exploitation, public exploit code, or significant community discussion surrounding this CVE.
