EUVD-2025-204762

Comprehensive Technical Analysis of EUVD-2025-204762

1. Vulnerability Assessment and Severity Evaluation

The vulnerability described in EUVD-2025-204762 is an authentication bypass issue in Xiongmai XM530 IP cameras running Firmware V5.00.R02.000807D8.10010.346624.S.ONVIF 21.06. This vulnerability allows unauthenticated remote attackers to access sensitive device information and live video streams due to the failure of the ONVIF implementation to enforce authentication on 31 critical endpoints.

Severity Evaluation:

• Base Score: 9.8 (Critical)
• Base Score Version: CVSS:3.1
• Base Score Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H

The CVSS score of 9.8 indicates a critical vulnerability. The high confidentiality, integrity, and availability impact, combined with the low attack complexity and network vector, make this a severe threat.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Unauthenticated Access: Attackers can exploit the lack of authentication on critical endpoints to access sensitive information and live video streams without any credentials.
• Network-Based Attacks: Given the network vector (AV:N), attackers can remotely exploit this vulnerability over the internet.

Exploitation Methods:

• Direct Access: Attackers can directly access the unauthenticated endpoints to retrieve live video feeds and device information.
• Automated Scripts: Malicious actors can use automated scripts to scan for vulnerable devices and exploit them en masse.
• Man-in-the-Middle (MitM) Attacks: Attackers can intercept and manipulate the data being transmitted, further compromising the integrity and confidentiality of the information.

3. Affected Systems and Software Versions

Affected Systems:

• Xiongmai XM530 IP cameras

Affected Software Versions:

• Firmware V5.00.R02.000807D8.10010.346624.S.ONVIF 21.06

4. Recommended Mitigation Strategies

Immediate Mitigation:

• Network Segmentation: Isolate vulnerable devices from the public internet and place them on a separate, restricted network segment.
• Firewall Rules: Implement strict firewall rules to block unauthorized access to the vulnerable endpoints.
• Monitoring: Increase monitoring and logging of network traffic to detect any suspicious activity.

Long-Term Mitigation:

• Firmware Update: Apply the latest firmware updates provided by the vendor to address the vulnerability.
• Authentication Enforcement: Ensure that all endpoints enforce proper authentication mechanisms.
• Regular Audits: Conduct regular security audits and vulnerability assessments to identify and mitigate similar issues.

5. Impact on European Cybersecurity Landscape
