Last modified

CVE-2013-4545 is a vulnerability of currently unknown severity. 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.. EPSS estimates a 3.08% chance of exploitation in the next 30 days.
