Comprehensive Technical Analysis of CVE-2024-6265

1. Vulnerability Assessment and Severity Evaluation

CVE ID: CVE-2024-6265 CVSS Score: 9.8

The vulnerability in the UsersWP plugin for WordPress is classified as a time-based SQL Injection (SQLi) vulnerability. The high CVSS score of 9.8 indicates a critical severity level, reflecting the potential for significant impact on affected systems. The vulnerability arises from insufficient escaping and preparation of SQL queries, specifically involving the uwp_sort_by parameter. This allows unauthenticated attackers to manipulate SQL queries, potentially leading to unauthorized data extraction.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Unauthenticated Access: Attackers can exploit this vulnerability without needing to authenticate, making it a high-risk vector.
• SQL Injection: By injecting malicious SQL code into the uwp_sort_by parameter, attackers can manipulate database queries to extract sensitive information.

Exploitation Methods:

• Time-Based SQL Injection: Attackers can use time-based techniques to infer the structure and content of the database by observing the time taken to execute queries.
• Data Exfiltration: By crafting specific SQL queries, attackers can extract user credentials, personal information, and other sensitive data stored in the database.

3. Affected Systems and Software Versions
