Threat & Defense at a Glance

What attackers do: exploitation maps to Data from Local System (T1005). What defenders deploy: see the NIST 800-53 controls recommended below.

Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

CM-6 Configuration Settings good match

prevent

Enforces secure configuration settings such as setting android:allowBackup="false" in AndroidManifest.xml to prevent unauthorized backup extraction of sensitive data.

SC-28 Protection of Information at Rest good match

prevent

Implements cryptographic protection for sensitive information at rest, ensuring data remains confidential even if accessed via enabled Android backup functionality.

AC-19 Access Control for Mobile Devices good match

prevent

Establishes usage restrictions and access controls for mobile devices, including disabling unnecessary backup features and encrypting sensitive app data.

MITRE ATT&CK Enterprise TechniquesAI

T1005 Data from Local System Collection

Adversaries may search local system sources, such as file systems, configuration files, local databases, virtual machine files, or process memory, to find files of interest and sensitive data prior to Exfiltration.

Why these techniques?

The vulnerability's allowBackup=true setting combined with cleartext storage of sensitive data directly enables extraction of application data from local storage via Android backup, facilitating T1005 Data from Local System for collection of sensitive information.

NVD Description

An issue in KukuFM Android v1.12.7 (11207) allows attackers to access sensitive cleartext data via the android:allowBackup="true" in the ANdroidManifest.xml

Deeper analysisAI

CVE-2025-25758, published on 2025-03-20, affects the KukuFM Android application version 1.12.7 (build 11207). The vulnerability arises from the android:allowBackup="true" attribute in the AndroidManifest.xml file, which enables attackers to access sensitive data stored in cleartext. It is classified under CWE-312 (Cleartext Storage of Sensitive Information) with a CVSS v3.1 base score of 7.5 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N), indicating high severity due to significant confidentiality impact.

Any network-accessible attacker can exploit this issue without authentication, privileges, or user interaction. By leveraging Android's backup functionality, they can extract and access the application's sensitive cleartext data, potentially exposing user information or other confidential content stored locally.
