CVE-2013-5212Public exploitNetwork attack vector

Script execution via unsanitized Flash secret parameter

Published Feb 13, 2020 · Updated Aug 6, 2024

Cross-site scripting in EasyXDM before 2.4.18 allows remote attackers to execute script in an RPC endpoint through easyxdm.swf. The Flash createChannel callback accepts an unvalidated secret URI parameter, incorporates it into receivingChannelName, and passes the resulting debug text to ExternalInterface.call. Exploitation requires an exposed Socket or RPC page that can be forced to use Flash transport, attacker control of the secret parameter, and enabled debug logging.
