CVE-2022-28080

What it actually does

Royal Event Management System v1.0 contains a SQL injection vulnerability in the todate parameter. Because the vulnerable input is incorporated into backend SQL queries without sufficient validation or parameterization, an authenticated low-privileged remote attacker can alter query logic. Successful exploitation can allow unauthorized database reads, modification or deletion of records, authentication bypass depending on query context, extraction of sensitive event/user data, and potentially database-level denial of service. The CVSS vector indicates network exploitability, low attack complexity, no user interaction, and high confidentiality, integrity, and availability impact, but requires some level of application authentication.

Why it matters to the business

Exploitation can expose sensitive attendee, organizer, booking, payment-adjacent, or administrative data stored by the event management application and may allow attackers to alter or destroy operational records. This can disrupt event operations, damage trust, trigger incident response and notification obligations, and require database restoration or integrity review. Although it is not listed in CISA KEV, the EPSS score is elevated and exploit maturity is weaponized, so internet-exposed or lightly authenticated deployments should be treated as high priority.

How an attack unfolds

An attacker first obtains access to the Royal Event Management System application with any account level sufficient to reach the functionality using the todate parameter. They then submit crafted SQL syntax in the todate parameter instead of a normal date value. If the application concatenates this value into a SQL statement, the database interprets the attacker's payload as part of the query. The attacker can use error-based, boolean-based, time-based, or union-based SQL injection techniques to confirm exploitability, enumerate database structure, dump sensitive tables, modify application records, create or alter administrative users where database permissions permit, or issue destructive queries that impair availability. In automated attacks, a tool may iterate payloads against the vulnerable endpoint to enumerate schemas and extract data at scale.

How to fix it

Upgrade to a vendor-maintained or patched version if one is available. No fixed version was provided for the affected product, so organizations should contact the maintainer for a corrected release or apply code-level remediation before continued production use. The durable fix is to replace dynamic SQL string concatenation involving the todate parameter with parameterized queries or prepared statements, enforce strict server-side date validation using an allowlisted format, and ensure database errors are not exposed to users. Apply least-privilege database permissions so the application account cannot perform unnecessary administrative, schema modification, or bulk destructive operations. As interim mitigation, restrict access to the application and vulnerable workflow, require strong authentication, place the application behind a WAF or reverse proxy rule blocking SQL metacharacter patterns in todate, monitor suspicious requests, and back up the database before remediation activities.

How to confirm the fix worked

Confirm exposure by inventorying deployments of Royal Event Management System v1.0 and identifying any endpoint or request flow that accepts a todate parameter. In a test environment or an approved maintenance window, submit benign SQL injection probes such as a single quote, doubled quote, boolean comparison, or database-specific time-delay payload in the todate parameter and verify that the application returns only normal validation errors and does not produce SQL errors, altered results, or response delays. Review the application code to confirm the parameter is passed through a prepared statement with bound parameters and strict date parsing. Validate that database permissions are least privilege and that application logs do not reveal SQL exceptions to users. After remediation, run a targeted dynamic application security test against the date-filtering functionality and confirm no SQL injection finding remains.

Typical attack path

1. Identify a Royal Event Management System v1.0 instance and reach the application over the network.
2. Authenticate with a low-privileged account or otherwise obtain access to the vulnerable feature.
3. Locate the request parameter named todate, likely in an event, report, booking, or date-filtering workflow.
4. Send SQL injection probes in the todate parameter, such as quote characters, boolean conditions, UNION SELECT tests, or time-delay expressions.
5. Confirm injection through SQL errors, changed response content, abnormal result counts, or measurable database response delays.
6. Enumerate database type, table names, column names, and application user data.
7. Extract sensitive records or credentials, or modify records and privileges if database permissions allow.
8. Optionally cover tracks by deleting or altering relevant application/database records, or trigger heavy queries/destructive operations causing service disruption.

How to detect it

Look for evidence of SQL injection attempts in web server access logs, reverse proxy logs, WAF alerts, application logs, and database audit/query logs involving the todate parameter. Prioritize requests where todate contains quotes, SQL comments, boolean expressions, UNION SELECT, stacked query separators, time-delay functions, or database metadata references. Review application logs for SQL syntax errors or unhandled database exceptions occurring after requests with abnormal todate values. In database logs, look for unexpected SELECTs against metadata tables, unusually broad queries, failed syntax attempts, time-delay functions, record modifications from the web application account, or large result exports. Investigate abnormal authentication events, creation or modification of administrative users, unexplained event/booking data changes, and spikes in database CPU or long-running queries. If threat hunting retrospectively, search from the publication date forward, with priority on periods where the application was internet-accessible or logs show automated scanning.

What your security team should do

• Immediately identify whether Royal Event Management System v1.0 is deployed, especially on internet-accessible systems.
• Prioritize remediation due to weaponized exploit maturity, high CVSS impact, and elevated EPSS despite absence from CISA KEV.
• If no vendor patch is available, implement code-level parameterized queries and strict date validation for the todate parameter.
• Restrict access to the vulnerable application or workflow until remediation is verified.
• Deploy temporary WAF or reverse proxy rules to block SQL injection patterns in the todate parameter.
• Review application, web server, WAF, and database logs for historical exploitation attempts and successful data access anomalies.
• Rotate credentials stored in or used by the application if exploitation is suspected.
• Back up the database and verify restore procedures before patching or making code changes.
• Harden the application database account to least privilege and remove unnecessary write, delete, schema, or administrative rights.
• Perform post-remediation penetration testing or DAST focused on SQL injection in date filter parameters.
