CVE-2019-25562: Jetaudio Buffer Overflow DOS Vulnerability

CVE-2019-25562 Overview

CVE-2019-25562 is a buffer overflow vulnerability affecting jetAudio version 8.1.7, specifically within the video converter component. This vulnerability allows local attackers to crash the application by supplying an oversized string in the File Naming field. An attacker can paste a malicious buffer of 512 bytes into the File Naming parameter and trigger the crash by clicking the Preview button, resulting in a denial of service condition.

Critical Impact

Local attackers can exploit this buffer overflow to cause application crashes and denial of service in jetAudio 8.1.7's video converter functionality.

Affected Products

• jetAudio 8.1.7
• jetAudio video converter component

Technical Details for CVE-2019-25562

Vulnerability Analysis

This vulnerability is classified as CWE-787 (Out-of-bounds Write), a type of memory corruption flaw that occurs when the software writes data past the end, or before the beginning, of the intended buffer. The jetAudio video converter component fails to properly validate the length of user-supplied input in the File Naming field before copying it into a fixed-size buffer.

The attack requires local access and user interaction, as the attacker must have the ability to input data into the application's File Naming field and then trigger the Preview functionality. While this limits the attack surface compared to network-exploitable vulnerabilities, it remains a significant concern in shared computing environments or scenarios where an attacker can convince a user to paste malicious content.

Root Cause

The root cause of this vulnerability is improper input validation in the video converter component's File Naming parameter handler. The application allocates a fixed-size buffer for the file naming string but does not enforce appropriate bounds checking when processing user input. When a string exceeding 512 bytes is supplied, the application writes beyond the allocated buffer boundaries, corrupting adjacent memory and causing the application to crash.

Attack Vector

The attack vector requires local access to the affected system with the ability to interact with the jetAudio application. The exploitation sequence involves:

1. Opening jetAudio 8.1.7 and accessing the video converter component
2. Pasting an oversized string (512+ bytes) into the File Naming field
3. Clicking the Preview button to trigger processing of the malicious input
4. The buffer overflow occurs during input processing, causing application crash

The vulnerability can be leveraged for denial of service attacks against the jetAudio application. Additional technical details are available in the Exploit-DB #46818 advisory and the VulnCheck Advisory.

Detection Methods for CVE-2019-25562

Indicators of Compromise

• Unexpected jetAudio application crashes, particularly when using the video converter component
• Windows Application event logs showing jetAudio.exe termination with access violation errors
• Crash dump files indicating memory corruption in the video converter module

Detection Strategies

• Monitor for repeated application crashes of jetAudio.exe with memory access violation exceptions
• Implement endpoint detection rules for applications crashing after processing unusually large input strings
• Use application whitelisting to restrict which users can execute jetAudio in sensitive environments

Monitoring Recommendations

• Enable Windows Error Reporting to capture crash telemetry from jetAudio
• Deploy endpoint protection solutions capable of detecting buffer overflow exploitation attempts
• Audit systems for the presence of vulnerable jetAudio version 8.1.7 installations

How to Mitigate CVE-2019-25562

Immediate Actions Required

• Identify all systems running jetAudio version 8.1.7 and assess their exposure
• Consider upgrading to a newer version of jetAudio if available, or evaluate alternative media applications
• Restrict access to the video converter functionality in shared computing environments
• Educate users about the risks of pasting untrusted content into application input fields

Patch Information

No vendor patch information is currently available in the CVE data. Organizations should monitor the JetAudio Official Website for security updates. If no patch is available, consider implementing the workarounds below or migrating to alternative software.

Workarounds

• Avoid using the video converter component in jetAudio 8.1.7 until a patch is available
• Implement application-level restrictions to prevent users from pasting large strings into input fields
• Use alternative media conversion software that does not contain this vulnerability
• Deploy endpoint protection solutions that can detect and block buffer overflow exploitation attempts
