Overview
CVE-2025-66423 is a high-severity access control vulnerability affecting Tryton, an open-source enterprise resource planning (ERP) system. Specifically, versions 6.0 before 7.6.11 do not properly enforce access rights for the HTML editor route. This flaw allows unauthorized users to potentially access or manipulate sensitive data within the Tryton system via the HTML editor, bypassing intended security measures. Patches are available in versions 7.6.11, 7.4.21, 7.0.40, and 6.0.70.
Technical Details
The vulnerability lies in the lack of proper access control checks on the route responsible for handling requests to the HTML editor functionality within Tryton. This means that an attacker, potentially without proper authentication or authorization, could potentially access this route. This could lead to unauthorized access to resources or unintended modifications through manipulation of the HTML editor. The root cause is within the trytond (Tryton daemon) component, specifically in how it handles routing and permission checks for editor-related requests.
CVSS Analysis
This vulnerability has been assigned a CVSS score of 7.1, indicating a high severity. The CVSS vector highlights the following characteristics:
- Attack Vector: Network (AV:N)
- Attack Complexity: Low (AC:L)
- Privileges Required: None (PR:N)
- User Interaction: Required (UI:R) – Potentially requiring user interaction for exploitation.
- Scope: Changed (S:C)
- Confidentiality Impact: High (C:H)
- Integrity Impact: High (I:H)
- Availability Impact: None (A:N)
The high confidentiality and integrity impact, coupled with the network attack vector, makes this a serious vulnerability that should be addressed promptly.
Possible Impact
Exploitation of CVE-2025-66423 could have significant consequences for Tryton users:
- Data Breach: Unauthorized access to sensitive data, including customer information, financial records, and business-critical documents.
- Data Manipulation: Modification or deletion of data, leading to inaccurate records and potentially disrupting business operations.
- System Compromise: In some scenarios, successful exploitation could lead to further compromise of the Tryton system or the underlying infrastructure.
- Reputational Damage: A successful attack can severely damage an organization’s reputation and erode customer trust.
Mitigation and Patch Steps
