CVE-2009-1723: Apple Mac OS X

Medium severity, CVSS 4.3. EPSS: 1.4% chance of exploitation in the next 30 days.

CFNetwork in Apple Mac OS X 10.5 before 10.5.8 places an incorrect URL in a certificate warning in certain 302 redirection scenarios, which makes it easier for remote attackers to trick a user into visiting an arbitrary https web site by leveraging an open redirect vulnerability, a different issue than CVE-2009-2062.
