Security readout for executives and security teams
Plain-English summary
CVE-2016-1000271 is an SQL injection in the Joomla DT Register extension. If a vulnerable site exposes this extension to the web, an attacker who can reach the web server may be able to manipulate database queries. This matters because event-registration sites may store attendee, payment, or contact data.
Executive priority
Prioritize quickly if DT Register is installed on any public Joomla site, especially where registration data is sensitive. If the extension is absent, no action is needed beyond documenting that validation.
Technical view
The issue affects DT Register versions before 3.1.12 on Joomla 3.x and before 2.8.18 on Joomla 2.5. The CVE describes SQL injection in the calendar raw events functionality involving the category parameter. No CVSS score, CWE, or CISA KEV listing is provided in the source bundle.
Likely exposure
Exposure is most likely for internet-facing Joomla sites running DT Register below the fixed version for their Joomla branch. Organizations without Joomla extension inventory may miss this because the CVE affected-product metadata is sparse.
Exploitation context
The CVE states exploitation appears possible when the attacker can reach the web server. Packet Storm is referenced as a public disclosure source. The provided sources do not establish active exploitation in the wild, and the CVE is not listed as KEV.
Researcher notes
The public record is thin: no CVSS, no CWE, and generic affected-product metadata. The strongest facts are the affected DT Register version ranges, Joomla branch mapping, reachability requirement, and Packet Storm reference. Treat impact assessment as environment-specific.
Mitigation direction
- Inventory Joomla sites for the DT Register extension.
- Upgrade DT Register to 3.1.12 or later on Joomla 3.x.
- Upgrade DT Register to 2.8.18 or later on Joomla 2.5.
- Restrict public access to vulnerable Joomla sites until updated.
- Check vendor or maintainer guidance for any additional hardening.
Validation and detection
- Confirm the installed DT Register version on each Joomla site.
- Verify whether affected sites are reachable from the internet.
- Review web logs for suspicious calendar raw event requests.
- Check database and application logs for unusual query errors.
- Retest after upgrade to confirm the vulnerable version is removed.
