Overview
CVE-2025-63214 describes a critical vulnerability discovered in BridgeTech VBC Server & Element Manager, specifically affecting firmware versions 6.5.0-10 and 6.5.0-9. This vulnerability allows unauthorized attackers to create and delete arbitrary user accounts, potentially leading to significant security breaches and system compromise.
Technical Details
The vulnerability stems from a broken access control issue within the BridgeTech VBC Server & Element Manager. Insufficient authorization checks allow attackers to bypass normal authentication mechanisms and directly manipulate user account data. The exact method of exploitation may involve crafted HTTP requests or other methods of injecting commands to the server.
According to publicly available information, the vulnerability was reported and analyzed by researchers who identified and demonstrated the ability to create and delete accounts without proper authentication.
CVSS Analysis
Currently, a CVSS score and severity rating are not available for CVE-2025-63214 (N/A). However, given the ability to create and delete user accounts, the vulnerability should be considered high severity. A CVSS score would likely be assigned once a formal analysis is conducted.
Factors contributing to a potentially high CVSS score include:
- Attack Vector: Network
- Attack Complexity: Low (likely)
- Privileges Required: None
- User Interaction: None
- Scope: Changed
- Confidentiality Impact: High
- Integrity Impact: High
- Availability Impact: High
Based on these factors, a CVSS v3.x score is likely to fall within the 8.0 – 10.0 range, indicating a critical vulnerability.
Possible Impact
The exploitation of CVE-2025-63214 can have severe consequences:
- Unauthorized Access: Attackers can create administrator accounts, granting them full control over the affected system.
- Data Breach: Attackers can access sensitive data stored on the server.
- Denial of Service: Attackers can delete legitimate user accounts, disrupting service for authorized users.
- System Compromise: Attackers can use compromised accounts to further compromise the entire system and potentially the network it is connected to.
- Reputational Damage: A successful attack can damage the reputation of BridgeTech and the organizations using their products.
Mitigation or Patch Steps
The primary mitigation step is to update the BridgeTech VBC Server & Element Manager to a patched version that addresses the vulnerability. Contact BridgeTech directly or visit their website for the latest firmware updates and security advisories.
In the meantime, consider the following temporary mitigation steps:
- Network Segmentation: Isolate the VBC Server & Element Manager from other critical systems to limit the potential impact of a breach.
- Access Control Lists (ACLs): Implement strict ACLs to restrict access to the VBC Server & Element Manager from unauthorized networks or IP addresses.
- Web Application Firewall (WAF): Deploy a WAF with rules that can detect and block malicious requests targeting the vulnerability. This may require custom rule creation based on the vulnerability details.
- Monitor Logs: Closely monitor server logs for suspicious activity, such as unauthorized account creation or deletion attempts.
