CVE-2019-25624: Pixarra Liquid Studio DOS Vulnerability

CVE-2019-25624 Overview

CVE-2019-25624 is a denial of service vulnerability affecting Pixarra Liquid Studio version 2.17. The vulnerability allows local attackers to crash the application by providing malformed input through the keyboard interface. When exploited, attackers can trigger the vulnerability by entering arbitrary characters during application runtime, causing the application to become unresponsive or terminate abnormally.

Critical Impact

Local attackers can cause application crashes and denial of service conditions in Pixarra Liquid Studio 2.17, potentially disrupting creative workflows and causing data loss for unsaved work.

Affected Products

• Pixarra Liquid Studio version 2.17

Technical Details for CVE-2019-25624

Vulnerability Analysis

This vulnerability is classified under CWE-606 (Unchecked Input for Loop Condition), indicating that the application fails to properly validate or sanitize user input before processing it. The local attack vector means an attacker must have access to the system where Liquid Studio is installed to exploit this vulnerability. While no authentication is required to trigger the condition, the impact is limited to availability—causing the application to crash without compromising confidentiality or integrity of data.

Root Cause

The root cause of this vulnerability lies in improper input validation within Pixarra Liquid Studio's keyboard input handling routines. When malformed or unexpected character sequences are entered during application runtime, the application fails to properly sanitize or handle these inputs. This lack of input validation can lead to unchecked loop conditions, causing the application to enter an unresponsive state or crash entirely.

Attack Vector

The attack vector for CVE-2019-25624 is local, requiring the attacker to have direct access to the system running Liquid Studio. The exploitation is straightforward:

1. The attacker opens or gains access to a running instance of Pixarra Liquid Studio 2.17
2. The attacker enters malformed or arbitrary characters through the keyboard interface
3. The application fails to properly handle the malformed input
4. The application becomes unresponsive or terminates abnormally

Since no proof-of-concept code is available from verified sources, technical details about specific character sequences that trigger the vulnerability can be found in the Exploit-DB entry #46128.

Detection Methods for CVE-2019-25624

Indicators of Compromise

• Unexpected application crashes or termination of Liquid Studio processes
• Application hang states where Liquid Studio becomes unresponsive to user input
• Windows Event Log entries indicating abnormal termination of TBLiquidStudio.exe
• Repeated application restarts in a short time period

Detection Strategies

• Monitor for abnormal process termination events related to Liquid Studio executables
• Implement application-level logging to detect input validation failures
• Use endpoint detection solutions to identify patterns of repeated application crashes
• Configure crash dump collection to analyze the root cause of application terminations

Monitoring Recommendations

• Enable Windows Application Event logging for crash events
• Deploy SentinelOne endpoint protection to detect and alert on application instability patterns
• Monitor system stability metrics for workstations running Liquid Studio
• Implement user behavior analytics to detect unusual interaction patterns with the application

How to Mitigate CVE-2019-25624

Immediate Actions Required

• Restrict access to systems running Pixarra Liquid Studio 2.17 to trusted users only
• Consider upgrading to a newer version of Liquid Studio if available from the vendor
• Implement application whitelisting to control what inputs can be processed
• Back up work frequently to minimize data loss in case of application crashes

Patch Information

No official patch information is available from Pixarra at this time. Users should check the Pixarra Official Website for any updated versions that may address this vulnerability. Additional advisory information is available from the VulnCheck Advisory.

Workarounds

• Limit local access to systems running the vulnerable software to trusted personnel only
• Implement process monitoring to automatically restart the application if it crashes
• Use application sandboxing technologies to isolate Liquid Studio from critical system resources
• Consider using alternative software until an official patch is released
• Deploy SentinelOne Singularity to monitor for and respond to application stability issues
