Remediation / Mitigation Strategy: CVE-2024-12368 - Odoo OAuth Token Export Vulnerability

This document outlines the remediation and mitigation strategy for CVE-2024-12368, an improper access control vulnerability in the Odoo auth_oauth module.

1. Vulnerability Description:

  • Vulnerability Name: CVE-2024-12368 - Improper Access Control in Odoo auth_oauth
  • Description: This vulnerability allows an authenticated, internal user to export the OAuth tokens of other users within the Odoo instance. This means an attacker with legitimate (but potentially low-privilege) access to the Odoo system can potentially steal the OAuth tokens of other users, including administrators or users with access to sensitive data.
  • Affected Versions: Odoo Community 15.0 and Odoo Enterprise 15.0.
  • Affected Module: auth_oauth

2. Severity Assessment:

  • CVSS Score: 8.1 (High)
    • CVSS v3.1 Vector: AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N
    • Explanation:
      • AV:N (Network): The vulnerability can be exploited over the network.
      • AC:L (Low): The attack requires no special access conditions.
      • PR:L (Low): An attacker requires low privileges to exploit the vulnerability.
      • UI:N (None): No user interaction is required.
      • S:U (Unchanged): The vulnerability doesn’t affect resources beyond the security scope of the vulnerable component.
      • C:H (High): There is a high impact to confidentiality. OAuth tokens can be used to impersonate users and access their data.
      • I:N (None): There is no impact to integrity.
      • A:N (None): There is no impact to availability.

3. Known Exploit:

  • While the specific exploit details might not be publicly available at the time of writing, the vulnerability description clearly indicates the attack vector: a low-privilege internal user can access and export OAuth tokens belonging to other users. This likely involves exploiting an improperly secured API endpoint or a flaw in the data access controls within the auth_oauth module. An attacker would likely leverage Odoo’s internal API to retrieve this data. PoC (Proof of Concept) exploits may emerge over time as security researchers analyze the vulnerability.

4. Remediation Strategy:

  • Primary Action: Upgrade to a Patched Version: The most effective remediation is to upgrade to a version of Odoo where this vulnerability has been addressed. Contact Odoo support or check the Odoo release notes for information on patched versions. This is the recommended approach.

  • Alternative/Temporary Mitigation (If Upgrade is Not Immediately Possible): These mitigations are provided with the understanding that they may not be complete and should not be considered a replacement for patching. Careful testing should be done to ensure these mitigations do not cause adverse effects to business operations.

    • Restrict auth_oauth Module Access: Where possible, restrict access to the auth_oauth module to only the necessary administrators. Review user roles and permissions to identify users who may have unnecessary access to this module. This reduces the attack surface. This might require custom access rules.

    • Monitor User Activity: Implement enhanced logging and monitoring to detect unusual activity related to the auth_oauth module, such as:

      • Excessive API calls related to OAuth token retrieval.
      • Unusual data exports from the auth_oauth module.
      • Login attempts from unusual locations after suspicious OAuth token activity.
      • Reviewing Odoo’s logs for suspicious activity is crucial.

    • Review OAuth Applications: Regularly review the OAuth applications configured within Odoo and remove any that are no longer needed or that have overly permissive access.

5. Mitigation Strategy:

  • Implementation: The remediation and mitigation steps should be implemented by qualified Odoo administrators or security professionals.
  • Testing: Thoroughly test the remediation steps in a staging environment before deploying them to production. Verify that the fixes do not introduce any new issues or break existing functionality.
  • Communication: Communicate the vulnerability and the remediation steps to all relevant stakeholders, including users, administrators, and management.
  • Documentation: Document the vulnerability, the remediation steps, and the testing results.
  • Timeline: Prioritize the implementation of the remediation steps based on the severity of the vulnerability and the potential impact to the organization. Upgrading to a patched version should be the top priority and done as quickly as possible. The other mitigation steps should be implemented immediately if upgrading is delayed.
  • Verification: After implementing the remediation, verify that the vulnerability has been successfully addressed by attempting to exploit it in a controlled environment. Consider using penetration testing or vulnerability scanning tools to confirm the effectiveness of the fix.

6. Post-Incident Review:

  • After the remediation has been completed, conduct a post-incident review to determine the root cause of the vulnerability and to identify any areas for improvement in the organization’s security practices.

Disclaimer: This remediation and mitigation strategy is based on the information provided and the general understanding of the vulnerability. It is not a substitute for professional security advice. Contact Odoo support or a qualified security consultant for assistance with implementing these steps.
