EUVD-2024-52660

Comprehensive Technical Analysis of EUVD-2024-52660

1. Vulnerability Assessment and Severity Evaluation

The vulnerability EUVD-2024-52660 pertains to the WAVLINK WN531P3 202383 device, which contains a hardcoded password in the /etc/shadow file. This allows attackers to log in as the root user, effectively granting them full administrative control over the device. The CVSS (Common Vulnerability Scoring System) base score of 9.8 indicates a critical severity level. The scoring 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 (Network Vector): The vulnerability is exploitable over the network.
• AC:L (Low Complexity): The attack requires low skill or resources.
• PR:N (No Privileges Required): No prior authentication is needed.
• UI:N (No User Interaction): No user interaction is required for exploitation.
• S:U (Unchanged Scope): The vulnerability does not change the security scope.
• C:H (High Confidentiality Impact): Complete loss of confidentiality.
• I:H (High Integrity Impact): Complete loss of integrity.
• A:H (High Availability Impact): Complete loss of availability.

This high severity score underscores the critical nature of the vulnerability, making it a top priority for immediate remediation.
