TITLE

Apple iOS of Multipeer Connectivity Vulnerability to retrieve plaintext multi-peer data in component convenience initializer

Trust: 0.8

sources: JVNDB: JVNDB-2015-004811

DESCRIPTION

The convenience initializer in the Multipeer Connectivity component in Apple iOS before 9 does not require an encrypted session, which allows local users to obtain cleartext multipeer data via an encrypted-to-unencrypted downgrade attack. Apple iOS is prone to multiple security vulnerabilities. Attackers can exploit these issues to bypass security restrictions, obtain sensitive information, execute arbitrary code, cause a denial-of-service condition, perform unauthorized actions and gain system privileges; this may aid in launching further attacks. Versions prior to iOS 9 are vulnerable. Apple iOS is an operating system developed by Apple (Apple) for mobile devices. Multipeer Connectivity is one of the components for creating applications that establish connections and exchange data at short distances via Wi-Fi or Bluetooth. The vulnerability is caused by the program not requiring session encryption
