Analyst readout for executives and security teams
Plain-English summary
A Joomla extension called User Bench version 1.0 has an unauthenticated SQL injection flaw. A remote attacker could query the site database and potentially expose credentials or configuration data. This matters most for organizations still running this old component on public Joomla sites.
Executive priority
Prioritize remediation for any public Joomla site using User Bench 1.0. The issue can expose sensitive database information without login, and public exploit information increases operational risk.
Technical view
CVE-2017-20254 is a CWE-89 SQL injection in Gegabyte User Bench 1.0 for Joomla. The reported vulnerable input is the userid parameter in the component’s detail view. The CVSS 4.0 score is 8.8, reflecting network access, low complexity, no privileges, and high confidentiality impact.
Likely exposure
Exposure is limited to Joomla sites with Gegabyte User Bench 1.0 installed, especially internet-facing sites. The provided sources do not confirm other versions, current maintenance status, or a vendor patch.
Exploitation context
A public ExploitDB reference exists, so proof-of-concept or exploit information is publicly available. The source bundle does not show CISA KEV listing or confirmed active exploitation in the wild.
Researcher notes
The record identifies User Bench 1.0 only. No safe fixed version is named in the provided sources. Treat remediation guidance as vendor-check, disable, or remove unless authoritative update information is found.
Mitigation direction
- Inventory Joomla sites for the User Bench component and version 1.0.
- If present, remove or disable the component if it is not business-critical.
- Check vendor or Joomla extension guidance for an updated fixed release.
- Restrict public access to affected component paths where feasible.
- Review database and application logs for suspicious access to the component.
Validation and detection
- Confirm whether User Bench is installed on each Joomla instance.
- Verify the installed component version from Joomla administration or extension records.
- Check web logs for requests targeting the User Bench detail view and userid input.
- Review database user privileges used by the Joomla application.
- Confirm compensating controls do not break required site functionality.

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.
