CVE-2025-24816 Overview
CVE-2025-24816 affects Nokia MantaRay, a network management platform used by telecommunications operators. The vulnerability stems from improper access control [CWE-284] within the product's API layer. Insufficient authorization checks allow an authenticated attacker to retrieve confidential information beyond their assigned privileges. The flaw does not require user interaction and is exploitable over the network with low privileges. Nokia published a security advisory documenting the issue and remediation guidance.
Critical Impact
An authenticated low-privileged user can access confidential data belonging to other tenants or administrative scopes through the MantaRay API, breaking role-based access control boundaries.

Technical Details for CVE-2025-24816
Vulnerability Analysis
The vulnerability is a Broken Access Control flaw in the Nokia MantaRay API. MantaRay exposes management endpoints that should enforce authorization checks tied to a caller's assigned role, scope, or tenant. The affected API endpoints fail to consistently validate whether the authenticated principal is permitted to access the requested resource. As a result, a user holding valid credentials can invoke API calls that return confidential data outside the boundaries of their assigned privileges.
The issue impacts confidentiality only. The advisory does not indicate integrity or availability effects, and successful exploitation does not modify system state. Because the flaw resides in server-side authorization logic, client-side controls in the MantaRay web console do not mitigate it. Attackers interact directly with the API, bypassing UI-driven role restrictions.
Root Cause
The root cause is insufficient authorization enforcement at the API layer, categorized under [CWE-284] Improper Access Control. The API validates authentication but does not adequately verify that the authenticated identity is authorized for the requested object or operation. This pattern is commonly referred to as a Broken Object Level Authorization (BOLA) or missing function-level access control issue in API security taxonomies.
Attack Vector
Exploitation requires network access to the MantaRay API and valid credentials for any account with low privileges. An attacker crafts API requests targeting endpoints or resource identifiers outside their assigned scope. The server processes these requests and returns data that should have been blocked. No user interaction is required, and the attacker does not need administrative privileges to trigger the flaw.
No verified proof-of-concept code is publicly available. Refer to the Nokia Security Advisory CVE-2025-24816 for vendor-supplied technical details.
Detection Methods for CVE-2025-24816
Indicators of Compromise
- API request logs showing authenticated users accessing resource identifiers, tenants, or object IDs outside their normal scope
- Unusual volumes of successful GET requests to MantaRay API endpoints from a single authenticated principal
- Access patterns where low-privileged accounts enumerate sequential or randomized object identifiers
Detection Strategies
- Enable verbose API access logging on MantaRay and forward logs to a centralized SIEM for correlation with user role assignments
- Baseline normal API usage per user role and alert on deviations, particularly requests to objects outside a user's expected scope
- Review authentication and authorization audit trails for anomalies during the exposure window prior to patching
Monitoring Recommendations
- Continuously ingest MantaRay API logs into a security data lake for retrospective hunting once indicators are known
- Correlate MantaRay account activity with identity provider logs to identify compromised or misused credentials
- Alert on privilege boundary violations by comparing requested resource ownership against the authenticated user's role
How to Mitigate CVE-2025-24816
Immediate Actions Required
- Consult the Nokia Security Advisory CVE-2025-24816 and apply the vendor-supplied fix for affected MantaRay versions
- Audit all MantaRay user accounts and remove or downgrade unnecessary privileged access
- Rotate credentials for any accounts suspected of misuse and review API access logs for unauthorized data retrieval
Patch Information
Nokia has published remediation guidance in the vendor advisory. Operators should coordinate with Nokia support to identify the fixed MantaRay release for their deployment and schedule the upgrade. No NVD CPE data is currently available to enumerate specific fixed versions.
Workarounds
- Restrict network access to the MantaRay API using firewall rules or management VLAN segmentation, limiting reachability to trusted operator workstations
- Enforce the principle of least privilege on MantaRay accounts to minimize the volume of data any single compromised account can retrieve
- Enable multi-factor authentication on upstream identity providers to reduce the risk of credential compromise
