CVE-2019-25657: AnyBurn 4.3 DOS Vulnerability

CVE-2019-25657 Overview

CVE-2019-25657 is a denial of service vulnerability affecting AnyBurn 4.3 x86, a CD/DVD/Blu-ray burning software. The vulnerability allows local attackers to crash the application by supplying an excessively long string to the image conversion function. Attackers can exploit this flaw by pasting a large buffer into the source or destination image file fields and clicking the Convert Now button, which triggers an application crash.

Critical Impact

Local attackers can cause denial of service by crashing the AnyBurn application through buffer manipulation in the image conversion functionality, disrupting user workflows and potentially causing data loss during burning operations.

Technical Details for CVE-2019-25657

Vulnerability Analysis

This denial of service vulnerability stems from improper input validation in the AnyBurn application's image conversion feature. The x86 version of AnyBurn 4.3 fails to properly validate the length of user-supplied input in the source and destination image file path fields before processing. When an attacker provides an excessively long string to these input fields, the application cannot handle the oversized data properly, resulting in an unhandled exception and subsequent application crash.

The vulnerability is classified under CWE-226 (Sensitive Information in Resource Not Removed Before Reuse), though the primary impact is availability rather than confidentiality. The attack requires local access and user interaction, as the attacker must paste the malicious buffer and initiate the conversion process.

Root Cause

The root cause of CVE-2019-25657 is insufficient input validation and boundary checking in the image conversion functionality of AnyBurn 4.3 x86. The application does not enforce proper length restrictions on user-supplied file path strings, allowing attackers to submit buffers that exceed expected boundaries. This lack of input sanitization causes the application to crash when attempting to process the oversized input data.

Attack Vector

The attack vector for CVE-2019-25657 is local, requiring the attacker to have access to the system running AnyBurn. The exploitation method involves the following steps:

1. The attacker launches the AnyBurn 4.3 x86 application
2. The attacker navigates to the image conversion functionality
3. A large buffer (excessively long string) is pasted into either the source image file field or destination image file field
4. The attacker clicks the "Convert Now" button to initiate the conversion
5. The application fails to handle the oversized input and crashes

The vulnerability requires user interaction in the sense that the malicious action must be triggered through the application's interface. For detailed technical information about this vulnerability, refer to the Exploit-DB #46289 entry and the VulnCheck Advisory on AnyBurn.

Detection Methods for CVE-2019-25657

Indicators of Compromise

• Unexpected AnyBurn application crashes, particularly during image conversion operations
• Process crash logs showing AnyBurn.exe terminating with access violation or buffer-related exceptions
• Unusually large strings in application memory dumps or crash reports related to file path handling

Detection Strategies

• Monitor for repeated AnyBurn application crashes on endpoints through endpoint detection and response (EDR) solutions
• Implement application crash monitoring to detect patterns of denial of service attempts
• Review Windows Event Logs for Application Error events (Event ID 1000) associated with AnyBurn.exe

Monitoring Recommendations

• Deploy SentinelOne agents to monitor for anomalous application behavior and crash patterns
• Configure alerts for repeated crashes of AnyBurn.exe within short time periods
• Monitor system stability metrics on endpoints where AnyBurn is installed

How to Mitigate CVE-2019-25657

Immediate Actions Required

• Upgrade AnyBurn to a patched version if available from the AnyBurn Official Website
• Restrict access to the AnyBurn application to trusted users only
• Consider using alternative CD/DVD burning software if no patch is available
• Implement application control policies to limit who can execute the vulnerable application

Patch Information

Users should check the AnyBurn Official Website for the latest version of the software that may contain fixes for this vulnerability. Review the vendor's release notes to confirm whether CVE-2019-25657 has been addressed in newer releases.

Workarounds

• Limit access to systems with AnyBurn installed to trusted users only
• Implement application whitelisting to prevent unauthorized execution of the vulnerable application
• Monitor and restrict clipboard operations in high-security environments where the application is used
• Consider using alternative disc burning utilities until a patch is confirmed available

Organizations should evaluate the necessity of AnyBurn in their environment and consider removing it if the image conversion feature is not essential to operations.
