CVE-2025-48695 is a privilege escalation vulnerability identified in CyberDAVA versions prior to 1.1.20. The vulnerability arises due to improper access control on a specific API endpoint: /api/v2/users/user/<user id>/role/ROLE/<Target role>. This endpoint allows modification of user roles without adequate verification of the requesting user's privileges. Consequently, a low-privileged user can exploit this flaw to escalate their privileges, potentially achieving administrative access. The vulnerability is categorized under CWE-266, which refers to incorrect privilege assignment, indicating that the system fails to enforce proper authorization checks before allowing role changes. The CVSS v3.1 base score is 6.4 (medium severity), with an attack vector of network (AV:N), low attack complexity (AC:L), requiring low privileges (PR:L), no user interaction (UI:N), and a scope change (S:C). The impact affects confidentiality and integrity but not availability. No known exploits have been reported in the wild yet, and no patches are currently linked, suggesting that organizations using affected versions should prioritize mitigation. The vulnerability's exploitation could allow unauthorized users to gain administrative control, leading to unauthorized data access, modification, or further compromise of the CyberDAVA environment.

For European organizations using CyberDAVA, this vulnerability poses a significant risk to internal security and data integrity. Given that CyberDAVA is likely used for digital asset or data management, unauthorized privilege escalation could lead to exposure or manipulation of sensitive information, violating GDPR and other data protection regulations. The ability to gain admin access without proper authorization could facilitate lateral movement within networks, data exfiltration, or sabotage of critical systems. This risk is heightened in sectors with stringent compliance requirements such as finance, healthcare, and government institutions. Additionally, the scope change in the vulnerability means that the attacker’s privileges extend beyond their initial scope, increasing the potential damage. The absence of known exploits does not diminish the threat, as the vulnerability is straightforward to exploit over the network without user interaction. European organizations must consider the reputational, financial, and regulatory consequences of a successful attack leveraging this flaw.

Organizations should immediately audit their CyberDAVA deployments to identify affected versions prior to 1.1.20. Until an official patch is released, implement strict network segmentation and access controls to limit access to the vulnerable API endpoint only to trusted administrators. Employ Web Application Firewalls (WAFs) with custom rules to detect and block unauthorized role modification attempts targeting the /api/v2/users/user/*/role/ROLE/* endpoint. Conduct thorough user privilege reviews to ensure no unnecessary low-privileged accounts exist that could be exploited. Monitor logs for suspicious API calls related to role changes. If possible, disable or restrict the vulnerable API endpoint temporarily. Additionally, enforce multi-factor authentication (MFA) for administrative accounts to reduce the impact of compromised credentials. Once a patch is available, prioritize its deployment and validate the fix through penetration testing focused on privilege escalation vectors.
