Comprehensive Technical Analysis of EUVD-2025-16220
1. Vulnerability Assessment and Severity Evaluation
Vulnerability Description: The vulnerability EUVD-2025-16220 affects multiple Sony network cameras, specifically the administrative interface, which allows the use of default credentials. This vulnerability is classified as critical with a CVSS base score of 9.2.
Severity Evaluation:
- CVSS Base Score: 9.2
- CVSS Version: 4.0
- CVSS Vector: CVSS:4.0/AV:N/AC:H/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N
The high base score indicates a severe vulnerability due to the potential for high confidentiality, integrity, and availability impacts. The attack complexity is high, and the attack vector is network-based, meaning it can be exploited remotely.
2. Potential Attack Vectors and Exploitation Methods
Attack Vectors:
- Remote Exploitation: The vulnerability can be exploited remotely, making it a significant threat.
- Default Credentials: Attackers can use default credentials to gain unauthorized access to the administrative interface.
Exploitation Methods:
- Credential Stuffing: Attackers may use automated tools to attempt default credentials across multiple devices.
- Brute Force Attacks: Although the complexity is high, brute force methods could be employed to guess the default credentials.
- Phishing: Social engineering techniques could be used to trick administrators into revealing default credentials.
3. Affected Systems and Software Versions
Affected Models and Versions:
- SNC-M1 (versions 1.0 to 1.30)
- SNC-M3 (versions 1.0 to 1.30)
- SNC-RZ25N (versions 1.0 to 1.30)
- SNC-RZ30N (versions 1.0 to 1.30)
