CVE-2019-25561 in Lyric Maker
Summary
by MITRE • 03/21/2026
Lyric Maker 2.0.1.0 contains a buffer overflow vulnerability that allows local attackers to crash the application by supplying an excessively long string in the Title field. Attackers can paste a 5000-byte buffer into the Title input field and save the file to trigger a denial of service condition.

The vulnerability identified as CVE-2019-25561 resides within Lyric Maker version 2.0.1.0, a software application designed for creating and managing lyric content. This particular flaw represents a classic buffer overflow condition that occurs when the application fails to properly validate input length before processing user-supplied data. The vulnerability specifically manifests in the Title field handling mechanism where the software does not enforce reasonable limits on string length, creating an exploitable condition that can be leveraged by local attackers with system access.
The technical implementation of this buffer overflow occurs when an attacker supplies an input string exceeding the allocated buffer space in the application's memory management structure. The vulnerability is triggered when a 5000-byte string is pasted into the Title field and subsequently saved as part of a file operation. This excessive input causes the program to write beyond the boundaries of the allocated memory buffer, resulting in memory corruption that leads to application instability and eventual crash. The flaw operates at the application layer where input validation mechanisms fail to prevent oversized data from being processed, making it a direct violation of secure coding practices.
From an operational perspective, this vulnerability presents a significant denial of service risk to users of Lyric Maker 2.0.1.0. The local nature of the attack means that an attacker must already have system access or be able to execute code on the target machine, but the impact remains severe as it can disrupt legitimate user workflows and potentially provide a foothold for further exploitation. The vulnerability affects the application's ability to function properly and can cause complete application failure, requiring manual restart and potentially data loss if the crash occurs during active file operations. This type of vulnerability can be particularly problematic in environments where the application is used for critical content creation tasks.
The vulnerability aligns with CWE-121, which describes stack-based buffer overflow conditions, and represents a failure in input validation and memory management practices. From an ATT&CK framework perspective, this vulnerability could be leveraged as part of a broader attack chain where initial access is gained through other means, and then used to establish persistence or escalate privileges. The local execution requirement suggests this vulnerability might be utilized as a post-exploitation tool rather than an initial access vector, but its potential for causing application instability makes it a valuable target for attackers seeking to disrupt operations. Organizations should implement immediate mitigations including software updates, input validation enforcement, and monitoring for unusual file creation patterns that might indicate exploitation attempts.
Security practitioners should consider this vulnerability as part of a comprehensive vulnerability management program, particularly focusing on applications that handle user input in untrusted environments. The lack of proper bounds checking in the Title field processing represents a fundamental security flaw that could potentially be extended to other input fields within the application. Regular security assessments of similar applications should be conducted to identify and remediate analogous buffer overflow conditions. The vulnerability demonstrates the critical importance of implementing robust input validation mechanisms and proper memory management practices in software development lifecycle processes, as these issues can be easily prevented through adherence to secure coding standards and thorough testing procedures.
