Comprehensive Technical Analysis of EUVD-2025-8764
1. Vulnerability Assessment and Severity Evaluation
The vulnerability EUVD-2025-8764, also known as CVE-2025-22941, is a command injection vulnerability in the web interface of Adtran 411 ONT L80.00.0011.M2. This vulnerability allows attackers to escalate privileges to root and execute arbitrary commands. The CVSS (Common Vulnerability Scoring System) base score of 9.8 indicates a critical severity level. The CVSS vector CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H breaks down as follows:
- AV:N (Attack Vector: Network): The vulnerability is exploitable over the network.
- AC:L (Attack Complexity: Low): The attack requires low complexity to exploit.
- PR:N (Privileges Required: None): No privileges are required to exploit the vulnerability.
- UI:N (User Interaction: None): No user interaction is required.
- S:U (Scope: Unchanged): The vulnerability does not change the security scope.
- C:H (Confidentiality: High): The vulnerability has a high impact on confidentiality.
- I:H (Integrity: High): The vulnerability has a high impact on integrity.
- A:H (Availability: High): The vulnerability has a high impact on availability.
Given these metrics, the vulnerability is highly critical and poses a significant risk to affected systems.
2. Potential Attack Vectors and Exploitation Methods
The primary attack vector for this vulnerability is through the web interface of the Adtran 411 ONT device. Attackers can exploit this vulnerability by injecting malicious commands into the web interface, which are then executed with root privileges. Potential exploitation methods include:
- Remote Command Execution: Attackers can send crafted HTTP requests to the web interface, injecting commands that are executed with root privileges.
- Privilege Escalation: Once an attacker gains initial access, they can escalate their privileges to root, allowing them to perform any action on the device.
- Data Exfiltration: With root access, attackers can exfiltrate sensitive data, including configuration files, logs, and other critical information.
- Denial of Service (DoS): Attackers can execute commands to disrupt the normal operation of the device, leading to a DoS condition.
3. Affected Systems and Software Versions
The vulnerability specifically affects Adtran 411 ONT devices running firmware version L80.00.0011.M2. It is crucial to identify all instances of this device within the network and ensure they are running a patched version of the firmware.
4. Recommended Mitigation Strategies
To mitigate the risk posed by this vulnerability, the following strategies are recommended:
- Firmware Update: Immediately update the firmware of all affected Adtran 411 ONT devices to a version that addresses this vulnerability.
- Network Segmentation: Implement network segmentation to isolate critical devices and limit the attack surface.
- Access Control: Enforce strict access controls to the web interface of the device, including the use of strong, unique passwords and multi-factor authentication (MFA).
- Monitoring and Logging: Implement robust monitoring and logging mechanisms to detect and respond to any suspicious activity on the device.
- Intrusion Detection/Prevention Systems (IDS/IPS): Deploy IDS/IPS to detect and prevent malicious traffic targeting the web interface of the device.
5. Impact on European Cybersecurity Landscape
The vulnerability poses a significant risk to the European cybersecurity landscape, particularly for organizations and individuals using Adtran 411 ONT devices. The potential for remote command execution and privilege escalation can lead to severe consequences, including data breaches, service disruptions, and unauthorized access to critical infrastructure.
