CVE-2025-9102 Details
Description
A security vulnerability has been detected in 1&1 Mail & Media mail.com App 8.8.0 on Android. Affected is an unknown function of the file AndroidManifest.xml of the component com.mail.mobile.android.mail. The manipulation leads to improper export of android application components. It is possible to launch the attack on the local host. The exploit has been disclosed to the public and may be used. The vendor was contacted early about this disclosure but did not respond in any way.
A task hijacking vulnerability has been identified in the 1&1 Mail & Media mail.com App version 8.8.0 for Android. This issue arises from an improper export of application components in the AndroidManifest.xml file, specifically within the com.mail.mobile.android.mail component. The vulnerability allows malicious applications to inherit permissions from the affected app, potentially leading to phishing attacks by manipulating user interactions and stealing sensitive information. This vulnerability affects all Android versions prior to Android 11.
To mitigate this vulnerability, developers should set the taskAffinity property of application activities in the AndroidManifest.xml file to an empty string or enforce a randomly generated task affinity. This prevents activities from sharing a task stack with other applications, thereby blocking potential task hijacking attacks.
