CVE-2026-30283: NIS Animal Sounds & Ringtones RCE Flaw

CVE-2026-30283 Overview

An arbitrary file overwrite vulnerability exists in PEAKSEL D.O.O. NIS Animal Sounds and Ringtones v1.3.0 that allows attackers to overwrite critical internal files via the file import process. This path traversal vulnerability (CWE-22) can lead to arbitrary code execution or information exposure when exploited.

Critical Impact

Attackers can leverage the insecure file import functionality to overwrite arbitrary system files, potentially achieving remote code execution or exposing sensitive information on affected devices.

Affected Products

• PEAKSEL D.O.O. NIS Animal Sounds and Ringtones v1.3.0
• Android mobile devices running the vulnerable application

Technical Details for CVE-2026-30283

Vulnerability Analysis

This vulnerability is classified as a path traversal issue (CWE-22) that manifests during the file import process within the NIS Animal Sounds and Ringtones mobile application. The application fails to properly sanitize user-controlled input when handling imported files, allowing attackers to specify directory traversal sequences that escape the intended file storage location.

The network-based attack vector indicates that remote exploitation is possible without requiring any user privileges or interaction. An attacker can craft malicious file names containing path traversal sequences (such as ../) to navigate outside the application's designated storage directory and overwrite arbitrary files on the device.

Root Cause

The root cause of this vulnerability lies in improper input validation within the file import functionality. The application does not adequately sanitize file path components during the import process, failing to strip or neutralize directory traversal sequences. This allows attackers to construct file paths that reference locations outside the application's sandboxed storage area.

When a user imports a file with a specially crafted filename, the application blindly accepts the path without validation, writing the file to an attacker-controlled location. This lack of proper path canonicalization and boundary enforcement is a classic manifestation of CWE-22 (Improper Limitation of a Pathname to a Restricted Directory).

Attack Vector

The attack can be executed remotely over the network, requiring no authentication or user interaction. An attacker could exploit this vulnerability by:

1. Crafting a malicious file with a path traversal sequence embedded in the filename
2. Tricking the application into processing this file through the import mechanism
3. The malicious filename causes the application to write content outside its designated directory
4. Overwriting critical application files or system configuration files
5. Achieving arbitrary code execution when the overwritten file is subsequently loaded or executed

The vulnerability allows for complete confidentiality, integrity, and availability compromise of the affected system.

Detection Methods for CVE-2026-30283

Indicators of Compromise

• Unexpected file modifications in system directories outside the application's data folder
• Presence of files with path traversal patterns (e.g., ../) in application logs or file system metadata
• Unusual application behavior following file import operations
• Modified or corrupted application configuration files

Detection Strategies

• Monitor file system operations for write attempts to directories outside the application sandbox
• Implement file integrity monitoring on critical system and application files
• Analyze application logs for import operations with suspicious filename patterns containing traversal sequences
• Deploy endpoint detection rules to identify path traversal attempts in mobile application contexts

Monitoring Recommendations

• Enable file system auditing to track file creation and modification events
• Configure alerts for write operations to sensitive system directories from the affected application
• Implement network traffic monitoring for potentially malicious file transfers to mobile devices
• Review application storage directories for unexpected file structures or content

How to Mitigate CVE-2026-30283

Immediate Actions Required

• Uninstall or disable PEAKSEL D.O.O. NIS Animal Sounds and Ringtones v1.3.0 until a patched version is available
• Restrict the application's file system permissions to the minimum required scope
• Avoid importing files from untrusted sources into the affected application
• Implement network-level controls to prevent malicious file delivery to affected devices

Patch Information

No official patch information has been released by the vendor at this time. Users should monitor the Peaksel official website for security updates and new application versions. Additional technical details regarding this vulnerability can be found in the GitHub Issue on CVEs maintained by SecSys FDU.

Workarounds

• Remove the vulnerable application from devices until a security update is available
• Use mobile device management (MDM) solutions to block installation of the affected application version
• Implement application sandboxing or containerization to limit file system access
• Avoid importing files from external or untrusted sources into the application

# Android ADB command to check if vulnerable app is installed
adb shell pm list packages | grep -i "animal"

# Remove the vulnerable application
adb uninstall com.peaksel.animalsounds
