Overview
CVE-2025-64064 is a critical vulnerability affecting Primakon Pi Portal version 1.0.18. This vulnerability allows low-privileged users to escalate their privileges to administrator level by exploiting a weakness in the access control mechanism within the `/api/v2/pp_users` endpoint. Specifically, the application fails to properly validate user permissions before processing PATCH requests aimed at modifying the `PP_SECURITY_PROFILE_ID`.
Technical Details
The vulnerability lies in the insufficient access control checks performed when handling PATCH requests to the `/api/v2/pp_users` endpoint. A low-level user can craft a malicious request containing `PP_SECURITY_PROFILE_ID=2` within the request body. Due to the lack of proper validation, the application will incorrectly update the user’s security profile, granting them administrative privileges. This circumvents the intended authorization scheme, allowing unauthorized users to gain complete control over the Primakon Pi Portal system.
CVSS Analysis
Due to the nature of missing information provided in the prompt, the CVSS score is currently unavailable. However, given the ability for low-privileged users to achieve full administrator access, a high to critical CVSS score is anticipated. Factors that would influence the final CVSS score include attack vector, attack complexity, privileges required, user interaction, scope, confidentiality impact, integrity impact, and availability impact. A full CVSS calculation will require more detailed information and may be available from the NVD or Primakon in the future.
Possible Impact
The exploitation of CVE-2025-64064 can have severe consequences, including:
- Complete System Takeover: Attackers can gain full control over the Primakon Pi Portal, allowing them to modify configurations, access sensitive data, and disrupt services.
- Data Breach: Unauthorized access to sensitive data, potentially including personal information, financial records, or confidential business data.
- Service Disruption: Attackers can disable or manipulate the Primakon Pi Portal, leading to significant downtime and disruption of business operations.
- Malware Deployment: The compromised system can be used as a launchpad for further attacks, including the deployment of malware to other systems on the network.
Mitigation and Patch Steps
The primary mitigation for CVE-2025-64064 is to upgrade Primakon Pi Portal to a patched version that addresses the insufficient access control checks. Contact Primakon support or visit their website for the latest security updates and patches.
In the meantime, if patching is not immediately possible, consider the following temporary workarounds:
- Network Segmentation: Isolate the Primakon Pi Portal system on a separate network segment to limit the potential impact of a successful attack.
- Implement Web Application Firewall (WAF) Rules: Create WAF rules to detect and block malicious requests targeting the `/api/v2/pp_users` endpoint. Specifically, monitor for requests attempting to modify the `PP_SECURITY_PROFILE_ID`.
- Monitor User Activity: Closely monitor user activity for any suspicious behavior, such as unexpected privilege escalations.
