CVE-2018-25274: InfraRecorder DoS Vulnerability

CVE-2018-25274 Overview

CVE-2018-25274 is a denial of service vulnerability affecting InfraRecorder version 0.53. The vulnerability allows local attackers to crash the application by importing a maliciously crafted text file. Specifically, attackers can create a text file containing 6000 bytes of data and import it through the Edit menu's Import function to trigger an application crash.

Critical Impact

Local attackers can cause application crash and denial of service by importing specially crafted text files through InfraRecorder's import functionality.

Affected Products

• InfraRecorder 0.53

Technical Details for CVE-2018-25274

Vulnerability Analysis

This vulnerability is classified under CWE-789 (Memory Allocation with Excessive Size Value), indicating that the application fails to properly validate or limit the size of imported data before processing. When a user imports a text file through the Edit menu's Import function, InfraRecorder does not adequately handle files with large data payloads, leading to resource exhaustion or memory corruption that causes the application to crash.

The attack requires local access to the system running InfraRecorder and user interaction to import the malicious file. While the vulnerability does not allow for remote exploitation or code execution, it effectively renders the application unusable, disrupting any disc burning workflows in progress.

Root Cause

The root cause of this vulnerability lies in improper input validation during the text file import process. InfraRecorder version 0.53 does not implement adequate bounds checking or memory allocation limits when processing imported text files. When a file containing approximately 6000 bytes of data is imported, the application's memory handling routines fail to properly manage the data, resulting in an unhandled exception and subsequent application crash.

Attack Vector

The attack vector is local, requiring an attacker to either have direct access to the target system or convince a user to import a malicious text file. The attack can be executed through the following steps:

1. Attacker creates a text file containing approximately 6000 bytes of data
2. The malicious file is placed on the target system or delivered to the victim
3. The victim opens InfraRecorder and navigates to Edit > Import
4. Upon selecting and importing the malicious text file, the application crashes

The vulnerability does not require elevated privileges and can be exploited by any user running InfraRecorder. Technical details and proof-of-concept information are available in the Exploit-DB #45413 advisory.

Detection Methods for CVE-2018-25274

Indicators of Compromise

• Unexpected InfraRecorder application crashes during file import operations
• Presence of suspiciously sized text files (approximately 6000 bytes) in user directories or temp folders
• Windows Event Log entries showing InfraRecorder process termination errors

Detection Strategies

• Monitor for repeated application crashes of InfraRecorder.exe process
• Implement file integrity monitoring to detect unusual text files being introduced to the system
• Review application error logs for unhandled exception events related to InfraRecorder

Monitoring Recommendations

• Configure endpoint monitoring to alert on InfraRecorder crash events
• Monitor file system activity for creation of text files with specific size patterns (around 6000 bytes) in locations commonly accessed by InfraRecorder

How to Mitigate CVE-2018-25274

Immediate Actions Required

• Avoid importing text files from untrusted sources in InfraRecorder version 0.53
• Consider using alternative disc burning software until the vulnerability is addressed
• Implement application whitelisting to control which files can be imported

Patch Information

No vendor patch information is currently available for this vulnerability. InfraRecorder is an open-source project, and users should monitor the project repository for potential updates. For additional technical details, refer to the VulnCheck Advisory.

Workarounds

• Disable or restrict access to the Import function if not required for your workflow
• Train users to only import files from trusted, verified sources
• Use file scanning solutions to inspect text files before importing them into InfraRecorder
• Consider migrating to actively maintained disc burning software alternatives

# Configuration example
# No specific mitigation configuration available
# Consider restricting file associations or using application control policies
# to limit import functionality on affected systems
