Vulnerability: SSL Server Spoofing in cURL and libcurl

CVE-2013-4545 · MEDIUM Severity

AV:N/AC:M/AU:N/C:N/I:P/A:N

cURL and libcurl 7.18.0 through 7.32.0, when built with OpenSSL, disables the certificate CN and SAN name field verification (CURLOPT_SSL_VERIFYHOST) when the digital signature verification (CURLOPT_SSL_VERIFYPEER) is disabled, which allows man-in-the-middle attackers to spoof SSL servers via an arbitrary valid certificate.
