Summary

CVE-2026-102428 is a critical, unauthenticated SQL injection vulnerability in the OrdaSoft Joomla CCK extension (component com_os_cck) for Joomla. The flaw stems from improper validation of a user-supplied "order column" parameter used in record sorting, allowing attackers to inject arbitrary SQL without any authentication. The issue is rated 9.3 (Critical) and is remotely exploitable over the network.

Technical details

  • Root cause: The parameter controlling the sort/order column for CCK records is accepted from user input and passed into a SQL query without proper sanitization or parameterization (CWE-89).
  • Trigger conditions: An attacker sends a crafted request to a Joomla site running the vulnerable OrdaSoft CCK component, manipulating the order-column parameter to inject SQL syntax.
  • Attack vector: Network-based; no authentication and no user interaction required.
  • Impact: Successful exploitation can allow reading, modifying, or exfiltrating database contents, and may lead to full compromise of data confidentiality, integrity, and availability depending on database permissions and site configuration.

Affected software

  • OrdaSoft Joomla CCK extension (com_os_cck), versions 1.0.0 through 8.3.15
  • Fixed in version 8.3.16

Severity

  • CVSS v4.0 Base Score: 9.3 (Critical)
  • Vector: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N

Mitigation and recommended actions

  • Immediate: Upgrade the OrdaSoft Joomla CCK extension to version 8.3.16 or later, where the order-column input is properly validated.
  • If immediate patching is not possible:
    • Restrict or disable public access to the affected CCK component’s front-end endpoints until the update can be applied.
    • Deploy a web application firewall (WAF) rule to detect and block SQL injection patterns targeting CCK sorting/order parameters.
    • Monitor web server and database logs for anomalous queries or errors referencing the CCK component.
    • Review database accounts used by Joomla/CCK for least-privilege access to limit the impact of any successful injection.

How IONIX’s External Exposure Management Platform Detects and Validates
Zero-Days to Shrink MTTR

1

Map your entire attack surface (continously)

IONIX uses multi-factor discovery methods, including DNS analysis, certificate mapping, metadata inspection, and more, to automatically map every internet-facing asset across your environment. This includes cloud instances, third-party platforms, shadow IT, and even forgotten infrastructure that traditional tools miss.

2

Monitor for new CVEs

Dozens of threat intel feeds using agentic technology are continuously analyzed to detect the appearance of proof-of-concept code, exploit kits, and indicators of active targeting. IONIX goes further by applying AI to proactively evaluate whether emerging vulnerabilities are likely to be exploited, even before PoCs go public.

3

Identify Potential External Exposures

Not all CVEs matter. IONIX filters vulnerabilities by asking attacker-centric questions: Can it be reached from the internet? Does it require authentication? Is it being exploited in the wild? This dramatically reduces noise and focuses teams on threats that can actually be weaponized.

4

Create Safe, Scalable Exploit Validations

IONIX transforms real-world PoCs into safe, non-intrusive test payloads that can be run in production environments without disruption. These simulations are precisely targeted to the systems that are vulnerable, ensuring rapid validation without unnecessary load.

5

Execute Exploit Validations

By combining context about software stack, versioning, exposure status, and reachability, IONIX ensures that only the right payloads are executed against the right assets, maximizing efficiency and minimizing risk.

6

Drive Fast and Actionable Remediation

Results are routed through integrations with ticketing, SOAR, and SIEM tools. Issues are written in plain language, bundled into remediation clusters, and prioritized based on asset criticality, exploitability, and blast radius. This shortens mean time to remediation (MTTR) and empowers teams to act with confidence.
