CVE-2019-25560: Lyric Video Creator DoS Vulnerability

CVE-2019-25560 Overview

CVE-2019-25560 is a denial of service vulnerability affecting Lyric Video Creator version 2.1. The application fails to properly validate MP3 files when processing them through the Browse song functionality, allowing attackers to crash the application by providing a specially crafted malformed MP3 file containing an oversized buffer.

Critical Impact

Attackers can remotely trigger an application crash by tricking users into opening a malicious MP3 file, leading to denial of service and potential data loss for unsaved projects.

Affected Products

• Lyric Video Creator 2.1
• Windows-based systems running vulnerable versions

Technical Details for CVE-2019-25560

Vulnerability Analysis

This vulnerability is classified under CWE-226 (Sensitive Information in Resource Not Removed Before Reuse). The core issue stems from improper handling of MP3 file metadata when users attempt to browse and select audio files within the application. When Lyric Video Creator 2.1 processes an MP3 file, it allocates a buffer to store file data but fails to adequately validate the size of incoming data before processing.

An attacker can craft a malicious MP3 file with an oversized buffer that exceeds expected boundaries. When a user opens this file through the application's "Browse song" feature, the application attempts to process the malformed data, leading to an unhandled exception and subsequent application crash.

Root Cause

The root cause of this vulnerability lies in insufficient input validation during MP3 file parsing. The application does not properly verify the size and structure of MP3 file headers and metadata before allocating memory buffers. This allows malformed files with excessively large data segments to trigger buffer-related errors, resulting in denial of service conditions.

Attack Vector

The attack requires user interaction—specifically, the victim must open a malicious MP3 file using the Lyric Video Creator application's file browsing functionality. The attack vector is network-based, as the malicious file can be distributed via email attachments, file sharing platforms, or malicious websites. Once the victim opens the crafted MP3 file, the application crashes immediately without proper error handling.

The exploitation mechanism involves creating an MP3 file with manipulated header fields that specify an oversized buffer. Technical details and a proof-of-concept are documented in the Exploit-DB #46816 advisory.

Detection Methods for CVE-2019-25560

Indicators of Compromise

• Unexpected crashes of Lyric Video Creator application when opening MP3 files
• Presence of unusually large or malformed MP3 files in user download directories
• Application crash logs indicating buffer-related exceptions during file parsing operations

Detection Strategies

• Monitor for abnormal termination events related to LyricVideoCreator.exe process
• Implement file integrity monitoring for MP3 files with abnormal header structures
• Deploy endpoint detection rules that flag applications crashing when processing media files
• Analyze crash dumps for patterns consistent with buffer overflow or memory allocation failures

Monitoring Recommendations

• Configure application crash monitoring on endpoints running Lyric Video Creator
• Enable logging of file access events for media file directories
• Implement behavioral analysis to detect repeated application crashes from the same source file
• Monitor network traffic for distribution of suspicious MP3 files to users

How to Mitigate CVE-2019-25560

Immediate Actions Required

• Avoid opening MP3 files from untrusted or unknown sources in Lyric Video Creator
• Consider using alternative software until a patched version is available
• Implement strict file source policies for multimedia content
• Educate users about the risks of opening files from untrusted sources

Patch Information

No official vendor patch has been identified in the available CVE data. Users should check the Lyric Video Creator Homepage for any security updates or newer versions that may address this vulnerability. The VulnCheck Advisory provides additional technical details about the vulnerability.

Workarounds

• Use endpoint protection solutions to scan and quarantine malicious MP3 files before they reach users
• Implement email filtering to block or sandbox MP3 attachments from external sources
• Configure download policies to prevent automatic execution of media files
• Consider application whitelisting to prevent execution of vulnerable software versions

# Example: Block MP3 files from untrusted locations using Windows AppLocker
# Create a rule to prevent Lyric Video Creator from opening files outside trusted directories
# PowerShell script to audit MP3 file access
