CVE-2025-28200

Comprehensive Technical Analysis of CVE-2025-28200

1. Vulnerability Assessment and Severity Evaluation

CVE ID: CVE-2025-28200 Description: Victure RX1800 EN_V1.0.0_r12_110933 utilizes a weak default password that includes the last 8 digits of the MAC address. CVSS Score: 9.8

The CVSS score of 9.8 indicates a critical vulnerability. This high score is due to the ease of exploitation and the significant impact on confidentiality, integrity, and availability. The use of a weak default password, especially one derived from a predictable source like the MAC address, makes the device highly susceptible to unauthorized access.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Network Scanning: Attackers can scan the network to identify devices with the Victure RX1800 MAC address.
• Brute Force Attacks: Given the predictable nature of the password, brute force attacks can be highly effective.
• Default Credential Exploitation: Attackers can use the known default password scheme to gain unauthorized access.

Exploitation Methods:

• Remote Access: Attackers can remotely access the device using the default credentials.
• Lateral Movement: Once access is gained, attackers can move laterally within the network to compromise other devices.
• Data Exfiltration: Sensitive information can be exfiltrated from the compromised device.

3. Affected Systems and Software Versions

Affected Systems:

• Victure RX1800 Wi-Fi routers running firmware version EN_V1.0.0_r12_110933.

Software Versions:

• EN_V1.0.0_r12_110933

4. Recommended Mitigation Strategies

Immediate Actions:

• Change Default Passwords: Immediately change the default password to a strong, unique password.
• Firmware Update: Apply any available firmware updates that address this vulnerability.
• Network Segmentation: Implement network segmentation to limit the potential impact of a compromised device.

Long-Term Strategies:

• Regular Audits: Conduct regular security audits to identify and mitigate vulnerabilities.
• User Education: Educate users on the importance of changing default credentials and maintaining strong passwords.
• Intrusion Detection Systems (IDS): Deploy IDS to monitor for suspicious activity and potential exploitation attempts.
