CVE-2019-25624 Overview
CVE-2019-25624 is a denial of service vulnerability in Pixarra Liquid Studio version 2.17. The flaw allows a local attacker to crash the application by supplying malformed keyboard input during runtime. The application fails to validate arbitrary character sequences entered through its input interface, causing it to become unresponsive or terminate abnormally. The vulnerability is tracked under [CWE-606: Unchecked Input for Loop Condition] and affects availability only, with no impact on confidentiality or integrity.
Critical Impact
A local attacker with access to the running application can trigger an availability loss in Liquid Studio 2.17 by submitting malformed keyboard input, forcing the process to crash or hang.
Affected Products
- Pixarra Liquid Studio 2.17
- Windows installations using tbliquidstudio_install.exe
- Any workstation running the vulnerable Liquid Studio build

Technical Details for CVE-2019-25624
Vulnerability Analysis
The vulnerability resides in how Liquid Studio 2.17 handles user-supplied keyboard input. The application accepts arbitrary character sequences without enforcing length or content validation. When a local user enters malformed input, the program enters an unrecoverable state. The process either hangs indefinitely or terminates abnormally, producing a denial of service condition on the affected workstation.
The issue is classified under [CWE-606], which covers unchecked input used in loop or processing conditions. Because the attack vector is local and requires no privileges or user interaction beyond access to the running application, the impact is limited to availability of the Liquid Studio process itself. No code execution, privilege escalation, or data disclosure is possible through this flaw.
Root Cause
Liquid Studio 2.17 does not sanitize or bound-check characters supplied through its keyboard input handler. The lack of input validation allows malformed sequences to reach internal processing routines that cannot handle unexpected data. The result is an exception or processing loop that the application does not recover from.
Attack Vector
An attacker with local interactive access to a session running Liquid Studio 2.17 can trigger the crash. The attacker types or injects arbitrary characters into the application during runtime. No authentication, elevated privileges, or social engineering is required beyond access to the open application window.
No verified proof-of-concept code is reproduced here. Technical details are documented in Exploit-DB #46128 and the VulnCheck Denial of Service Advisory.
Detection Methods for CVE-2019-25624
Indicators of Compromise
- Unexpected termination of the tbliquidstudio.exe process on workstations running version 2.17
- Windows Application event log entries showing application hangs or faulting modules tied to Liquid Studio
- User reports of Liquid Studio becoming unresponsive shortly after typing in the application
Detection Strategies
- Inventory endpoints for installations of Pixarra Liquid Studio 2.17 using software asset management tooling
- Monitor for repeated crash events of the Liquid Studio process within short time windows on the same host
- Correlate local logon sessions with Liquid Studio crash events to identify potentially abusive interactive activity
Monitoring Recommendations
- Forward Windows Application and Reliability event logs to a centralized log platform for crash trend analysis
- Alert on Event ID 1000 (Application Error) and Event ID 1002 (Application Hang) referencing Liquid Studio binaries
- Track local user sessions on multi-user workstations where Liquid Studio is installed
How to Mitigate CVE-2019-25624
Immediate Actions Required
- Identify all hosts running Pixarra Liquid Studio 2.17 and prioritize remediation on shared or multi-user systems
- Restrict local access to systems running Liquid Studio to trusted users only
- Avoid running Liquid Studio in contexts where untrusted users have keyboard access to the active session
Patch Information
No vendor patch is referenced in the published CVE data. Consult the Pixarra Official Website for any updated builds. If no fixed version is available, treat the affected version as end-of-support for security purposes and consider migrating to an alternative product.
Workarounds
- Remove or uninstall Liquid Studio 2.17 from systems where it is not required
- Limit interactive logon rights on workstations hosting the vulnerable application
- Save work frequently to minimize data loss if the application is crashed by malformed input
# Configuration example: enumerate Liquid Studio installations via PowerShell
