Attack Chain

1. An unauthenticated attacker sends a malicious HTTP request to the WordPress site.
2. The request targets an endpoint that utilizes the JoomSport plugin.
3. The attacker crafts the request to include a ‘sortf’ parameter containing a time-based blind SQL injection payload.
4. The JoomSport plugin processes the request without properly sanitizing the ‘sortf’ parameter.
5. The unsanitized input is incorporated into an SQL query executed against the WordPress database.
6. The injected SQL code leverages time-based delays to infer information about the database structure and content.
7. The attacker analyzes the response times to determine the results of the injected SQL queries.
8. Through repeated requests, the attacker extracts sensitive information, such as usernames, passwords, or other confidential data stored in the database.

Impact

Successful exploitation of this vulnerability allows unauthenticated attackers to extract sensitive data from the WordPress database. This could include usernames, passwords, email addresses, and other confidential information. The impact ranges from data breaches and compromised user accounts to potential defacement of the website and further malicious activities. If the database contains sensitive financial data, the consequences could be even more severe.

Recommendation

• Upgrade the JoomSport – for Sports: Team & League, Football, Hockey & more plugin to the latest version to patch CVE-2026-6929.
• Deploy the Sigma rule “Detect CVE-2026-6929 Exploitation Attempt via JoomSport SQL Injection” to your SIEM to identify potential exploitation attempts.
• Monitor web server logs for suspicious requests containing SQL injection payloads in the ‘sortf’ parameter to identify and block malicious activity.
