Overview
CVE-2025-64063 identifies a significant security vulnerability in Primakon Pi Portal version 1.0.18. This flaw allows standard users to bypass UI restrictions and directly interact with administrative API endpoints. By crafting direct HTTP requests, attackers can manipulate data beyond their authorized scope, leading to unauthorized account modification, confidential data access, and ultimately, privilege escalation.
Technical Details
The core of the vulnerability lies in the insufficient authorization checks within the Pi Portal’s API. A standard user can send direct HTTP requests to administrative endpoints, effectively circumventing the intended user interface controls. Specific attack vectors include:
- Unauthorized Account Modification: Attackers can modify or delete arbitrary user accounts and change passwords by directly accessing the user management API.
- Confidential Data Access: Sensitive organizational documents can be accessed and downloaded by exploiting the document retrieval API.
- Privilege Escalation: By manipulating core system functions through direct API calls, attackers can elevate their privileges and gain complete control over the system.
CVSS Analysis
Unfortunately, a CVSS score and severity level have not yet been assigned to CVE-2025-64063. However, based on the potential impact described, it is highly likely that this vulnerability will receive a high to critical CVSS score upon evaluation, given the possibility of complete data compromise and privilege escalation.
Severity: N/A
CVSS Score: N/A
Possible Impact
The exploitation of CVE-2025-64063 can have severe consequences, including:
- Complete Data Breach: Unauthorized access to sensitive organizational documents and data.
- Data Manipulation and Corruption: Modification or deletion of critical data, leading to data integrity issues.
- Account Takeover: Malicious actors gaining control of user accounts, including administrative accounts.
- System Compromise: Complete control over the Pi Portal system, allowing attackers to perform any desired action.
- Reputational Damage: Loss of trust and damage to the organization’s reputation.
Mitigation and Patch Steps
Immediate action is required to mitigate the risk posed by CVE-2025-64063. The following steps are recommended:
- Apply the Patch: Check the Primakon website for an official patch or updated version of Pi Portal 1.0.18. Apply the patch as soon as it becomes available.
- Implement Network Segmentation: Isolate the Pi Portal system from other critical systems to limit the potential impact of a successful attack.
- Web Application Firewall (WAF): Deploy a WAF to filter malicious requests and prevent unauthorized access to the API endpoints. Configure the WAF to block direct access to administrative API endpoints from standard user sessions.
- Monitor System Logs: Carefully monitor system logs for suspicious activity, such as unusual API requests or unauthorized access attempts.
- Temporary Mitigation (if no patch available): As a temporary measure, implement strict access control rules at the network level to restrict access to the Pi Portal’s API endpoints. Only allow access from trusted sources and authorized users. This should only be considered as a short-term solution until a proper patch is available.
