Comprehensive Technical Analysis of EUVD-2025-199868
1. Vulnerability Assessment and Severity Evaluation
The vulnerability described in EUVD-2025-199868 pertains to a privilege escalation issue in the UsersController::edit function of the Cerebrate software before version 1.30. This vulnerability allows an authenticated, non-privileged user to elevate their privileges by manipulating the role_id or organisation_id fields in the user-edit endpoint request.
Severity Evaluation:
- Base Score: 9.4 (CVSS 4.0)
- Vector String: CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H
The high base score indicates a critical vulnerability due to the potential for significant impact on confidentiality, integrity, and availability. The attack complexity is low, and the attack vector is network-based, requiring high privileges but no user interaction.
2. Potential Attack Vectors and Exploitation Methods
Attack Vectors:
- Authenticated User Exploitation: An authenticated user with non-privileged access can exploit this vulnerability by crafting a malicious request to the user-edit endpoint.
- Internal Network Attacks: Attackers with access to the internal network can exploit this vulnerability to gain higher privileges, potentially leading to further compromise.
Exploitation Methods:
- Direct Manipulation: Modifying the
role_idororganisation_idfields in the edit request to assign higher privileges. - Automated Scripts: Using automated scripts to send crafted requests to the vulnerable endpoint, potentially allowing for mass privilege escalation.
3. Affected Systems and Software Versions
