Address Book in Apple Mac OS X before 10.7.3 automatically switches to unencrypted sessions upon failure of encrypted connections, which allows remote attackers to read CardDAV data by terminating an encrypted connection and then sniffing the network.

Security readout for executives and security teams

This flaw could let an attacker read contact data if Address Book fell back from encrypted CardDAV to unencrypted communication. The issue affects Apple Mac OS X before 10.7.3. Business impact is mainly confidentiality of address book data, especially on hostile or shared networks. Exposure is likely limited to legacy Apple Mac OS X systems before 10.7.3 using Address Book with CardDAV accounts. Modern supported macOS estates are unlikely to be affected, but legacy devices should be checked. Treat this as a legacy confidentiality risk. Prioritize only if old Mac OS X systems still exist, especially where contact data is sensitive or devices use untrusted networks. Mitigation focus: Apply Apple Mac OS X 10.7.3 or later vendor-supported security updates.; Identify and retire unsupported Mac OS X systems before 10.7.3.; Avoid CardDAV address book synchronization on untrusted networks until upgraded..
