Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
Loop with Unreachable Exit Condition ('Infinite Loop') vulnerability in datavane tis (tis-console/src/main/java/com/qlangtech/tis/runtime/module/action modules). This vulnerability is associated with program files ChangeDomainAction.Java. This issue affects tis: before v4.3.0.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · moderate confidence

An infinite loop vulnerability exists in the ChangeDomainAction.java file within the tis-console module of datavane tis. The loop lacks a reachable exit condition, causing the application to hang or become unresponsive when this code path is triggered.

MitigationUpgrade to tis v4.3.0 or later which contains the fix for this infinite loop vulnerability. If immediate upgrade is not possible, review and modify the loop logic in ChangeDomainAction.java to ensure proper exit conditions are reachable.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Locate the tis-console module
    Search for the tis-console module in your tis installation directory or source code repository. Look for the file ChangeDomainAction.java within the module.
    Affected if The tis-console module with ChangeDomainAction.java is present in your environment
  2. Identify the installed tis version
    Check your tis installation for the version number - typically found in a version file, pom.xml, or the application's startup logs. Common locations include the root directory's version.properties or the tis-console module's pom.xml.
    Affected if Your installed version is earlier than v4.3.0 (the fixed version)
  3. Inspect the loop logic in ChangeDomainAction.java
    Open ChangeDomainAction.java and locate any while/for loops. Examine the loop condition and any break/return statements inside the loop to determine if there is a reachable exit condition.
    Affected if The loop lacks a reachable exit condition - the loop can iterate indefinitely based on the condition logic
  4. Verify the vulnerable code path is reachable
    Review the code to determine if ChangeDomainAction is invoked by your application. Check if there are any authentication checks or conditions that prevent the infinite loop code path from being triggered.
    Affected if The ChangeDomainAction can be triggered without proper guards preventing the infinite loop execution

Your environment is affected if you are running tis versions earlier than v4.3.0 and the ChangeDomainAction.java file contains an unreachable exit condition in its loop logic that can be triggered by your application.
