CVE-2026-12593 in Axivion
Summary
by MITRE • 07/09/2026
The implementation of an internal and undocumented Dashboard API endpoint (POST /api/users/~/{user}/tokens) forgot to ensure an HTTP request for creating an API Token for another user had sufficient permission to do so.
Precondition for successful exploitation was a preexisting internal user (with more privileges than the attacker), the attacker knowing its login name and the attacker being able to authenticate to the Dashboard via OAuth/OIDC. The attacker would then have had to forge a token creation API request on behalf of the other user and could have authenticated and finalized the token creation with their own OAuth/OIDC credentials. In the worst case, this would mean an attacker could have become Dashboard Administrator and been able to perform all administrative actions if the preexisting internal user had administrative privileges. In combination with a separate weakness, this could have further led to code execution on the host system running the Dashboard with the privileges of the OS-User running the Dashboard server.

This vulnerability represents a critical authorization flaw in the dashboard application's api token management system where the implementation failed to properly validate user permissions when creating tokens for other users through an undocumented endpoint. The specific api endpoint POST /api/users/~/{user}/tokens lacks proper access control checks that should verify whether the authenticated user has sufficient privileges to create tokens on behalf of another user account. This oversight creates a privilege escalation vector that directly violates fundamental security principles of least privilege and principle of least authority.
The vulnerability stems from a design flaw where the system assumes all authenticated users can create tokens for any other user based on the endpoint's path structure without implementing proper authorization logic. The precondition requirements indicate that an attacker must already possess a valid oauth/oidc session and knowledge of a target user's login name, but once these conditions are met, the system fails to validate whether the requesting user has appropriate administrative rights to perform such actions. This represents a classic case of insufficient authorization checks that can be categorized under cwe-285: permissions, privileges, and access control flaws.
The operational impact of this vulnerability extends beyond simple privilege escalation into potential full system compromise when combined with other weaknesses present in the system architecture. If the preexisting internal user account possesses administrative privileges, an attacker could effectively assume complete administrative control over the dashboard application, enabling them to perform any administrative action including user management, configuration changes, data manipulation, and potentially accessing sensitive system information. The severity classification aligns with attack technique t1078: valid accounts, as it exploits legitimate authentication mechanisms while leveraging authorization bypass.
When combined with a separate underlying weakness that allows code execution on the host system, this vulnerability could enable attackers to achieve remote code execution with the privileges of the operating system user running the dashboard server. The exploitation chain demonstrates how authorization flaws can compound into critical system compromise scenarios, making this vulnerability particularly dangerous from an operational security perspective. Mitigation strategies should include implementing proper access control validation for all api endpoints, enforcing strict permission checks before token creation, and ensuring comprehensive audit logging of token creation activities to detect unauthorized attempts.
The vulnerability highlights the importance of applying principle of least privilege at every layer of application architecture and demonstrates how undocumented features can create unexpected security gaps. Security controls should be validated against attack techniques such as t1548.003: legitimate credentials, which specifically addresses abuse of privileged accounts through legitimate access mechanisms. Organizations should implement comprehensive authorization testing including privilege escalation scenarios during security assessments to identify such gaps in their api implementations and ensure proper enforcement of access control policies across all system interfaces.
The technical implementation failure represents a breakdown in defense in depth principles where multiple security controls should have prevented unauthorized token creation for other users. Proper solution would involve implementing role-based access control checks that validate the requesting user's permissions against target user accounts, ensuring that only users with appropriate administrative privileges can create tokens for other users. Additionally, all internal api endpoints should undergo rigorous security review processes to identify and remediate similar authorization flaws before deployment in production environments.
