Description: The Ultimate Member – User Profile, Registration, Login, Member Directory, Content Restriction & Membership Plugin for WordPress is vulnerable to SQL Injection via the 'sorting' parameter in versions 2.1.3 to 2.8.2. This vulnerability arises due to insufficient escaping on the user-supplied parameter and lack of sufficient preparation on the existing SQL query.

CVSS Score: 9.8

Severity Evaluation:

• Critical: A CVSS score of 9.8 indicates a critical vulnerability. The high score is due to the potential for unauthenticated attackers to extract sensitive information from the database, leading to significant data breaches and potential loss of confidentiality, integrity, and availability.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Unauthenticated Access: The vulnerability can be exploited by unauthenticated attackers, meaning anyone with access to the web application can attempt to exploit it.
• SQL Injection: The primary attack vector is SQL Injection, where malicious SQL statements are inserted into an entry field for execution.

Exploitation Methods:

• Manipulating the 'sorting' Parameter: Attackers can manipulate the 'sorting' parameter to inject malicious SQL code. For example, they might append SQL commands to extract data or alter the database.
• Automated Tools: Attackers may use automated tools to scan for and exploit SQL Injection vulnerabilities, making it easier to target multiple sites.
