CVE-2024-25850

Comprehensive Technical Analysis of CVE-2024-25850

1. Vulnerability Assessment and Severity Evaluation

CVE ID: CVE-2024-25850 CVSS Score: 9.8

The CVSS score of 9.8 indicates that this vulnerability is critical. The high score is likely due to the potential for complete system compromise, ease of exploitation, and the lack of user interaction required for exploitation. Command injection vulnerabilities are particularly dangerous because they allow attackers to execute arbitrary commands on the affected system, potentially leading to full control over the device.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Remote Exploitation: An attacker can exploit this vulnerability remotely by sending crafted requests to the device.
• Network-Based Attacks: Given that the vulnerability is in a network device, attackers can leverage network access to send malicious payloads.

Exploitation Methods:

• Command Injection: The attacker can inject malicious commands through the wps_ap_ssid5g parameter, which the device will execute without proper sanitization.
• Payload Delivery: The attacker can deliver payloads that execute commands to gain unauthorized access, escalate privileges, or disrupt services.

3. Affected Systems and Software Versions

Affected Systems:

• Netis WF2780 v2.1.40144

Software Versions:

• Firmware version 2.1.40144

It is crucial to note that other versions of the Netis WF2780 or similar devices might also be affected if they share the same codebase or have not been patched for this specific vulnerability.

4. Recommended Mitigation Strategies

Immediate Actions:

• Firmware Update: Ensure that the device firmware is updated to the latest version provided by the vendor.
• Network Segmentation: Isolate the affected device from critical network segments to limit potential damage.
