Status: ModifiedLow (2.6)—

CFNetwork in Apple Mac OS X 10.4 through 10.4.7 and 10.3.9 allows remote SSL sites to appear as trusted sites by using encryption without authentication, which can cause the lock icon in Safari to be displayed even when the site's identity cannot be trusted.

CVSS

Exploitation probability (EPSS)

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
