CVE-2025-6890 Overview
CVE-2025-6890 is a SQL injection vulnerability in code-projects Movie Ticketing System 1.0. The flaw resides in /ticketConfirmation.php where the Date parameter is passed unsanitized into a backend SQL query. Authenticated remote attackers can manipulate the parameter to inject arbitrary SQL statements. The exploit has been publicly disclosed, increasing the risk of opportunistic abuse against exposed deployments. The vulnerability is tracked under [CWE-74] (Improper Neutralization of Special Elements in Output Used by a Downstream Component).
Critical Impact
Remote attackers with low-privilege access can inject SQL through the Date parameter of /ticketConfirmation.php, exposing booking data and potentially modifying database contents.

Technical Details for CVE-2025-6890
Vulnerability Analysis
The vulnerability is a SQL injection flaw in the ticket confirmation workflow of Movie Ticketing System 1.0. The Date request parameter is concatenated into a SQL query without parameterization or input filtering. An attacker submitting crafted input through the Date argument can break out of the original query context and append additional SQL syntax. The application executes the injected statement against the backend database with the privileges of the web application's database user. Public proof-of-concept material has been linked from third-party trackers, which lowers the skill barrier for exploitation.
Root Cause
The root cause is improper neutralization of user-supplied input before it reaches the SQL interpreter. /ticketConfirmation.php treats the Date parameter as a trusted string and embeds it directly into a query. The application lacks prepared statements, parameter binding, and type validation, which would normally separate code from data.
Attack Vector
Exploitation occurs over the network against the HTTP endpoint serving /ticketConfirmation.php. The attacker needs low-privilege access to reach the page and then submits a tampered Date value containing SQL metacharacters. Successful injection can disclose booking records, user details, or other database contents and may permit data tampering depending on the database account's permissions.
No verified exploit code is reproduced here. Technical details are available through the GitHub PoC Issue #31 and VulDB entry #314369.
Detection Methods for CVE-2025-6890
Indicators of Compromise
- HTTP requests to /ticketConfirmation.php containing SQL metacharacters such as ', --, UNION, SELECT, or SLEEP( in the Date parameter.
- Web server access logs showing unusually long or URL-encoded Date values.
- Database error messages or stack traces returned to clients when querying ticket confirmation pages.
Detection Strategies
- Inspect web application firewall (WAF) logs for SQL injection signatures targeting the Date parameter on the ticket confirmation endpoint.
- Correlate authentication events with anomalous query patterns originating from the application's database account.
- Hunt for repeated 500-series responses on /ticketConfirmation.php paired with parameter fuzzing behavior from a single source.
Monitoring Recommendations
- Enable verbose query logging on the backend database and alert on syntactically anomalous queries originating from the application.
- Monitor outbound traffic from the web server for unexpected data egress that may follow successful extraction.
- Track new accounts, schema changes, or privilege grants in the booking database as post-exploitation indicators.
How to Mitigate CVE-2025-6890
Immediate Actions Required
- Restrict network access to the Movie Ticketing System until a fix is applied, ideally placing it behind an authenticated reverse proxy or VPN.
- Deploy WAF rules that block SQL metacharacters in the Date parameter of /ticketConfirmation.php.
- Rotate database credentials used by the application and review the account's privileges, removing write or administrative rights where not required.
Patch Information
No official vendor patch is referenced in the published CVE data. Operators should monitor the Code Projects Resource Hub for vendor updates and consider replacing or forking the application to apply source-level fixes that use parameterized queries.
Workarounds
- Modify /ticketConfirmation.php to use prepared statements with bound parameters for the Date value.
- Apply strict server-side input validation that accepts only ISO date formats (e.g., YYYY-MM-DD) and rejects all other input.
- Disable verbose database error reporting in production to prevent leakage of schema information during probing.
