The Data Security component in Apple iOS before 5 and Apple TV before 4.4 does not properly restrict use of the MD5 hash algorithm within X.509 certificates, which makes it easier for man-in-the-middle attackers to spoof servers or obtain sensitive information via a crafted certificate.

Security readout for executives and security teams

Older Apple iOS and Apple TV versions accepted MD5-based X.509 certificates too loosely. That could let an attacker positioned between a user and a server impersonate that server and expose sensitive traffic. The issue matters mainly where very old Apple devices remain in use. Exposure is limited to Apple iOS versions before 5 and Apple TV versions before 4.4. Modern supported devices should not be affected based on the fixed-version wording in the CVE record. Treat this as a legacy-device risk. It is not supported by evidence of active exploitation here, but any remaining vulnerable devices create avoidable trust and data exposure risk on hostile networks. Mitigation focus: Upgrade affected iOS devices to iOS 5 or later where supported.; Upgrade affected Apple TV devices to 4.4 or later where supported.; Retire or isolate devices that cannot run fixed versions..
