CVE-2025-44083

Comprehensive Technical Analysis of CVE-2025-44083

1. Vulnerability Assessment and Severity Evaluation

CVE ID: CVE-2025-44083 CISA Vulnerability Name: CVE-2025-44083 Description: An issue in D-Link DI-8100 16.07.26A1 allows a remote attacker to bypass administrator login authentication. CVSS Score: 9.8

The CVSS score of 9.8 indicates a critical vulnerability. This high score is due to the potential for unauthorized access to administrative functions, which can lead to complete compromise of the affected device. The severity is amplified by the remote nature of the attack, meaning an attacker does not need physical access to exploit the vulnerability.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Remote Exploitation: The vulnerability allows remote attackers to bypass the authentication mechanism, gaining unauthorized access to the device's administrative interface.
• Network-Based Attacks: Attackers can exploit this vulnerability over the network, making it a significant threat for devices connected to the internet.

Exploitation Methods:

• Credential Bypass: The attacker can send specially crafted requests to the device's web interface, circumventing the login process.
• Automated Scripts: Attackers may use automated scripts to scan for vulnerable devices and exploit them en masse.

3. Affected Systems and Software Versions

Affected Systems:

• D-Link DI-8100 devices running firmware version 16.07.26A1.

Software Versions:

• Firmware version 16.07.26A1 for D-Link DI-8100.
