ChangYou Dolphin 12.0.2 for Android 12.0.2

The Backup and Restore feature in Mobotap Dolphin Browser for Android 12.0.2 suffers from an arbitrary file write vulnerability when attempting to restore browser settings from a malicious Dolphin Browser backup file. This arbitrary file write vulnerability allows an attacker to overwrite a specific executable in the Dolphin Browser's data directory with a crafted malicious executable. Every time the Dolphin Browser is launched, it will attempt to run the malicious executable from disk, thus executing the attacker's code.

The Dolphin Browser for Android 12.0.2 suffers from an insecure parsing implementation of the Intent URI scheme. This vulnerability could allow attackers to abuse this implementation through a malicious Intent URI, in order to invoke private Activities within the Dolphin Browser.
