This article details a bug encountered in Kibana version 8.19.0 within the Security Solution. The issue arises when a user attempts to revert a prebuilt rule to its original state after it has been modified and re-imported. This bug results in an error message and the rule failing to revert, leading to a potentially inconsistent security configuration. This article aims to provide a comprehensive understanding of the bug, its impact, and steps to reproduce it, and discusses the expected behavior versus the current behavior. Addressing such issues is critical for maintaining the integrity and reliability of security solutions, ensuring users can confidently manage their security rules and configurations. Understanding the root cause of this bug is crucial for developers to implement a fix and for users to avoid potential misconfigurations while a solution is being developed.

Bug Description

When a user imports a modified prebuilt rule and subsequently tries to revert it to its original version, an error occurs. The preview drawer, which should display the original rule details, appears empty. Despite the error message, a revert confirmation toast notification is also displayed, creating conflicting feedback. This behavior is unexpected as the rule does not actually revert to its previous state. This issue was observed in Kibana version 8.19.0, specifically build 85276 with commit e8d39e03e54d31dd03a19f45f51d46a9e0e8e462. The bug was identified using Google Chrome Version 138.0.7204.158 (Official Build) (64-bit), indicating that the issue is not browser-specific. The implications of this bug are significant, as it can lead to users believing a rule has been reverted when it has not, potentially compromising the security posture of the system. It is essential to address this bug promptly to ensure users can reliably manage and revert their security rules as intended. The error undermines the reliability of the revert function, which is a critical feature for maintaining a stable and predictable security environment.

Steps to Reproduce

To replicate the bug, follow these steps:

  1. Ensure Kibana 8.19 is running.
  2. Install a prebuilt rule and modify its properties, such as its name, description, and fields. This modification is crucial to trigger the bug.
  3. After saving the changes, observe that the “Modified” badge is displayed next to the prebuilt rule, along with the specific modified fields. This confirms that the rule has been successfully altered.
  4. Export the modified rule. This step is important as the bug is triggered after re-importing the rule.
  5. Revert the same rule after exporting it. This action should, in theory, restore the rule to its original state.
  6. Import the previously exported modified rule, ensuring you override the existing rule ID. Overriding the rule ID is a key step in reproducing the bug.
  7. After the import is successful, open the rule. Verify that all the modified data is displayed on the rule detail page. This confirms that the modified rule has been correctly imported.
  8. Click on the three dots (More Actions) menu and select “Revert to Elastic version.” This is the action that triggers the bug.
  9. Observe the preview drawer that opens. It will be empty, indicating that the original rule data is not being displayed. This is the first sign of the bug.
  10. Click the “Revert” button. An error message will be displayed, but a revert confirmation toast notification will also appear. This conflicting feedback is a critical symptom of the bug. The successful reproduction of the bug using these steps highlights a clear issue within the rule reversion process.

Current Behavior

The current behavior exhibits a significant issue: an error message is displayed when attempting to revert a modified rule after it has been imported. This error contradicts the revert confirmation toast notification that also appears, creating confusion for the user. The preview drawer, which should display the original rule details before reversion, remains empty. This indicates that the system is failing to retrieve and display the original rule configuration, which is a critical part of the reversion process. The primary concern is that the rule does not actually revert to its previous version despite the confirmation message. This can lead to a false sense of security and potential misconfigurations, as users may believe the rule is in its original state when it is not. This behavior undermines the reliability of the revert functionality and poses a risk to the overall security posture of the system. The inconsistent feedback, with both an error and a confirmation, further exacerbates the issue by misleading the user about the actual state of the rule.

Expected Behavior

The expected behavior is that no error should be displayed when performing a revert action for an imported modified rule. When a user clicks the “Revert to Elastic version” button, the preview drawer should accurately display the original details of the rule, allowing the user to confirm the changes before proceeding. Upon clicking the “Revert” button, the rule should seamlessly revert to its original state without any errors or inconsistencies. A clear and accurate confirmation message should be displayed, indicating that the rule has been successfully reverted. This process should be reliable and predictable, ensuring that users can confidently restore rules to their original configurations as needed. The absence of errors is crucial for maintaining user trust and ensuring the integrity of the security solution. The revert functionality should serve as a safe and dependable mechanism for undoing changes, providing users with the assurance that they can easily correct any unintended modifications. The correct behavior of the revert action is essential for maintaining the stability and security of the system.

Impact and Implications

The bug described in this article has significant implications for users of Kibana's Security Solution. The primary impact is the unreliability of the revert action, a critical feature for managing security rules. When users cannot confidently revert modified rules to their original state, it introduces a risk of misconfiguration and potential security vulnerabilities. The conflicting feedback, with an error message accompanied by a confirmation toast, further complicates the situation by misleading users about the actual state of the rule. This confusion can lead to incorrect assumptions and actions, potentially compromising the security posture of the system. Moreover, the inability to revert rules can disrupt workflows and increase the time and effort required to manage security configurations. If users are unable to undo changes easily, they may be hesitant to experiment with new rules or modifications, limiting the flexibility and adaptability of the security solution. The overall impact of this bug is a reduced level of trust in the system's ability to manage and maintain security rules effectively.
