CVE-2019-25561 Overview
CVE-2019-25561 is a buffer overflow vulnerability affecting Lyric Maker 2.0.1.0 that allows local attackers to crash the application through a denial of service attack. The vulnerability is triggered when an attacker supplies an excessively long string in the Title field, specifically a 5000-byte buffer, and saves the file. This causes the application to crash due to improper boundary checking when processing user input.
Critical Impact
Local attackers can reliably crash Lyric Maker 2.0.1.0 by exploiting improper input validation in the Title field, causing complete denial of service to users of the application.

Technical Details for CVE-2019-25561
Vulnerability Analysis
This vulnerability is classified under CWE-787 (Out-of-bounds Write), indicating that the application writes data beyond the boundaries of allocated memory buffers. When a user inputs an excessively long string into the Title field, Lyric Maker fails to properly validate the length of the input before copying it to a fixed-size buffer. This results in memory corruption that causes the application to crash.
The attack requires local access to the system where Lyric Maker is installed. No special privileges are needed to exploit this vulnerability, and no user interaction beyond the attacker's own actions is required. While the vulnerability does not compromise data confidentiality or integrity, it provides a reliable mechanism to disrupt application availability.
Root Cause
The root cause of CVE-2019-25561 is improper input validation in the Title field handling code. The application allocates a fixed-size buffer for storing the title string but does not implement proper bounds checking when copying user-supplied data into this buffer. When a string exceeding the buffer's capacity (such as a 5000-byte payload) is provided, the application writes beyond the allocated memory region, corrupting adjacent memory and causing a crash.
Attack Vector
The attack vector for this vulnerability is local, requiring the attacker to have access to a system running Lyric Maker 2.0.1.0. The exploitation process involves:
- Opening Lyric Maker 2.0.1.0 on the target system
- Pasting an oversized string (approximately 5000 bytes) into the Title input field
- Saving the file to trigger the buffer overflow
This triggers an out-of-bounds write condition that corrupts the application's memory state, resulting in an unhandled exception and application crash. Technical details and proof-of-concept information are available in the Exploit-DB #46817 entry.
Detection Methods for CVE-2019-25561
Indicators of Compromise
- Application crashes of Lyric Maker.exe with access violation or memory corruption errors
- Crash dump files indicating buffer overflow in the title processing routines
- Abnormally large .lyr or related project files with oversized title metadata
Detection Strategies
- Monitor for repeated crashes of Lyric Maker application processes on endpoints
- Implement application crash monitoring to detect potential exploitation attempts
- Review Windows Event Logs for application error events related to Lyric Maker
Monitoring Recommendations
- Configure endpoint detection solutions to alert on Lyric Maker application faults
- Enable crash reporting and analysis for desktop applications in enterprise environments
- Monitor file system activity for suspicious project files with abnormal metadata sizes
How to Mitigate CVE-2019-25561
Immediate Actions Required
- Consider discontinuing use of Lyric Maker 2.0.1.0 if denial of service is a concern
- Restrict access to systems running Lyric Maker to trusted users only
- Avoid opening untrusted project files in Lyric Maker
Patch Information
No vendor patch information is currently available for this vulnerability. Users should refer to the JetAudio Official Website for any future updates or replacement software. Additional advisory information can be found in the VulnCheck Advisory on Lyric Maker.
Workarounds
