Common Vulnerabilities and Exposures assigned an identifier <a href="https://access.redhat.com/security/cve/CVE-2007-5162">CVE-2007-5162</a> to the following vulnerability: The connect method in lib/net/http.rb in the (1) Net::HTTP and (2) Net::HTTPS libraries in Ruby 1.8.5 and 1.8.6 does not verify that the commonName (CN) field in a server certificate matches the domain name in an HTTPS request, which makes it easier for remote attackers to intercept SSL transmissions via a man-in-the-middle attack or spoofed web site.
