info:
  name: Quotes llama <= 3.1.5 - SQL Injection
  author: Abdullah Shahid (comradezephyr)
  severity: critical
  description: |
    Quotes llama 3.1.5 and earlier contains a time-based blind SQL injection vulnerability caused by improper control of a SQL identifier. The select_search() AJAX handler (registered for guests via wp_ajax_nopriv_select_search) reads the attacker-controlled 'sc' parameter from $_POST and substitutes it into the query through the malformed wpdb placeholder '%1s'.
  impact: |
    An unauthenticated attacker can extract sensitive data from the WordPress database, including user credentials and other stored information, through time-based blind SQL injection.
  remediation: |
    Update the Quotes llama plugin to version 3.1.6 or later.
