CVE-2019-25616: AnMing MP3 CD Burner Buffer Overflow Flaw

CVE-2019-25616 Overview

CVE-2019-25616 is a buffer overflow vulnerability in AnMing MP3 CD Burner 2.0 that allows local attackers to crash the application through a denial of service attack. The vulnerability exists in the registration name field input handling, where insufficient bounds checking permits an attacker to supply an oversized string that triggers an application crash.

Critical Impact

Local attackers can cause a denial of service condition by pasting a 6000-byte payload into the registration name field, leading to application crashes and potential service disruption.

Affected Products

• AnMing MP3 CD Burner version 2.0

Technical Details for CVE-2019-25616

Vulnerability Analysis

This buffer overflow vulnerability stems from improper input validation in the registration name field of AnMing MP3 CD Burner 2.0. The application fails to properly validate the length of user-supplied input before copying it into a fixed-size buffer, allowing attackers to overflow the allocated memory space.

When a user pastes an oversized string (approximately 6000 bytes) into the registration name field, the application attempts to store this data in a buffer that cannot accommodate the input size. This results in memory corruption that causes the application to crash, effectively creating a denial of service condition.

The vulnerability requires local access to the system, meaning an attacker must have the ability to interact with the application's user interface directly. While this limits the attack surface compared to remotely exploitable vulnerabilities, it still poses a risk in shared computing environments or scenarios where an attacker has limited local access.

Root Cause

The root cause is a classic buffer overflow due to insufficient input validation. The application's registration name field handler does not enforce proper length restrictions on user input before processing. When an attacker supplies an input string that exceeds the allocated buffer size, the excess data overwrites adjacent memory, corrupting the application's state and triggering a crash.

This vulnerability is classified under CWE-434 (Unrestricted Upload of File with Dangerous Type) in the CVE metadata, though the actual behavior aligns more closely with classic buffer overflow patterns (CWE-120/CWE-121). The lack of boundary checking in the input handling routine is the fundamental security flaw.

Attack Vector

The attack vector for CVE-2019-25616 is local, requiring the attacker to have direct access to the system running AnMing MP3 CD Burner 2.0. The exploitation process involves:

1. Opening the AnMing MP3 CD Burner application
2. Navigating to the registration dialog
3. Pasting an oversized payload (approximately 6000 bytes) into the registration name field
4. Triggering the buffer overflow when the application attempts to process the input

The vulnerability has a documented proof-of-concept available through Exploit-DB #46754. The attack does not require authentication or special privileges beyond the ability to run the application and interact with its interface.

Detection Methods for CVE-2019-25616

Indicators of Compromise

• Unexpected application crashes of AnMing MP3 CD Burner process
• Windows Event Log entries indicating application faults with exception code indicating buffer overrun
• Memory dump files generated from application crashes in the AnMing installation directory

Detection Strategies

• Monitor for repeated application crash events associated with AnMing MP3 CD Burner executables
• Implement endpoint detection rules that flag attempts to paste unusually large strings into application input fields
• Deploy application-level monitoring to detect anomalous memory access patterns

Monitoring Recommendations

• Enable Windows Error Reporting to capture crash dumps for forensic analysis
• Configure endpoint security solutions to alert on buffer overflow exploitation attempts
• Monitor process behavior for signs of memory corruption in multimedia applications

How to Mitigate CVE-2019-25616

Immediate Actions Required

• Consider removing or replacing AnMing MP3 CD Burner 2.0 with alternative software if the application is not essential
• Restrict local access to systems running the vulnerable application
• Implement application allowlisting to control which users can execute the software

Patch Information

No official patch has been identified for this vulnerability. The vendor, AnMing Software, has not released a security update addressing this buffer overflow issue. Users should consider the following alternatives:

• Contact the vendor through their homepage to inquire about security updates
• Review the VulnCheck Advisory for additional mitigation guidance
• Evaluate alternative CD burning software that is actively maintained and receives security updates

Workarounds

• Limit access to the AnMing MP3 CD Burner application to trusted users only
• Run the application in a sandboxed or isolated environment to contain potential crashes
• Disable or restrict access to the registration functionality if it is not required for normal operations
• Implement endpoint protection that can detect and prevent buffer overflow exploitation attempts
