Comprehensive Technical Analysis of EUVD-2025-205697
1. Vulnerability Assessment and Severity Evaluation
The vulnerability identified as EUVD-2025-205697, also known as CVE-2025-15102, pertains to a password protection bypass in the DVP-12SE11T device. The CVSS (Common Vulnerability Scoring System) base score of 9.1 indicates a critical severity level. The CVSS vector CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:H breaks down as follows:
- Attack Vector (AV): Network (N) - The vulnerability is exploitable over the network.
- Attack Complexity (AC): Low (L) - The attack requires minimal skill or resources.
- Privileges Required (PR): None (N) - No privileges are required to exploit the vulnerability.
- User Interaction (UI): None (N) - No user interaction is required.
- Scope (S): Unchanged (U) - The vulnerability does not change the security scope.
- Confidentiality (C): None (N) - There is no impact on confidentiality.
- Integrity (I): High (H) - There is a high impact on integrity.
- Availability (A): High (H) - There is a high impact on availability.
This high severity score underscores the critical nature of the vulnerability, which can lead to significant disruptions and potential data integrity issues.
2. Potential Attack Vectors and Exploitation Methods
Given the CVSS vector, the primary attack vector is network-based. Potential exploitation methods include:
- Remote Exploitation: An attacker can exploit the vulnerability over the network without needing physical access to the device.
- Automated Scripts: Due to the low attack complexity, automated scripts can be developed to scan for and exploit vulnerable devices.
- Man-in-the-Middle (MitM) Attacks: If the device communicates over unsecured channels, an attacker could intercept and manipulate data, bypassing password protections.
3. Affected Systems and Software Versions
The vulnerability affects the DVP-12SE11T device manufactured by Delta Electronics. Specifically, versions of the device software below 2.16 are impacted. Organizations using these versions are at risk and should prioritize updates or mitigation strategies.
