CVE-2021-24458: Popup box < 2.3.4 - Authenticated Blind SQL Injections

The get_ays_popupboxes() and get_popup_categories() functions of the Popup box WordPress plugin before 2.3.4 did not use whitelist or validate the orderby parameter before using it in SQL statements passed to the get_results() DB calls, leading to SQL injection issues in the admin dashboard

Security readout for executives and security teams

Plain-English summary

This flaw affects the Popup box WordPress plugin before 2.3.4. An authenticated user in the admin dashboard could influence database queries through an unchecked sorting parameter, creating a blind SQL injection risk. The sources do not provide CVSS scoring or evidence of active exploitation.

Executive priority

Treat this as a targeted WordPress plugin risk, not a broad emergency. Prioritize sites with the vulnerable plugin, many admin users, or exposed admin portals. Patch during the next security maintenance window unless privileged-account compromise is suspected.

Technical view

The plugin functions get_ays_popupboxes() and get_popup_categories() used an unvalidated orderby parameter inside SQL passed to WordPress get_results() calls. This is CWE-89 SQL injection, described as authenticated blind SQL injection in the admin dashboard for Popup box versions before 2.3.4.

Likely exposure

Exposure is likely limited to WordPress sites running the Popup box plugin before 2.3.4, especially where multiple users can access plugin admin dashboard functions. Internet-facing WordPress admin access increases operational risk.

Exploitation context

The provided sources do not state active exploitation, and CISA KEV status is false. The vulnerability is authenticated and admin-dashboard scoped, but SQL injection can still threaten database confidentiality and integrity if reachable by a privileged or compromised account.

Researcher notes

Evidence is specific but limited: vulnerable functions and parameter are named, but no CVSS vector, proof-of-concept status, or detailed vendor advisory is included in the source bundle. Avoid assuming unauthenticated reachability or active exploitation from these sources.

Mitigation direction

  • Inventory WordPress sites for the Popup box plugin and its installed version.
  • Upgrade affected installations to 2.3.4 or later, following vendor guidance.
  • Restrict WordPress admin access to trusted users and networks where practical.
  • Review admin accounts for unnecessary plugin management privileges.
  • Monitor vendor and WordPress plugin advisories for any updated remediation guidance.

Validation and detection

  • Confirm no production site runs Popup box versions before 2.3.4.
  • Verify plugin admin access is limited to expected trusted roles.
  • Review recent WordPress admin activity for unexpected plugin-dashboard use.
  • Check database and application logs for unusual query errors tied to the plugin.
  • Confirm backups exist before remediation and after version changes.

Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')

Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
