CVE-2007-5162: Ruby-Lang Ruby

Medium severity, CVSS 4.3. EPSS: 1.7% chance of exploitation in the next 30 days.

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.

Affected products

• Ruby-Lang Ruby: version 1.8.5 only; version 1.8.6 only
