CVE-2025-3337: Online Restaurant Management System SQLi

CVE-2025-3337 Overview

CVE-2025-3337 is a SQL injection vulnerability in codeprojects Online Restaurant Management System 1.0. The flaw exists in the /admin/member_update.php script, where the ID parameter is passed unsanitized into a backend SQL query. Remote attackers can manipulate this parameter to alter query logic, extract database contents, or modify records. The issue is classified under [CWE-74] (Improper Neutralization of Special Elements in Output). The exploit has been publicly disclosed, increasing the likelihood of opportunistic attacks against exposed instances.

Critical Impact

Unauthenticated remote attackers can inject SQL commands through the ID parameter of /admin/member_update.php, leading to potential disclosure or tampering of restaurant management data.

Technical Details for CVE-2025-3337

Vulnerability Analysis

The vulnerability resides in the administrative member update workflow of the Online Restaurant Management System. The member_update.php script accepts an ID parameter from the HTTP request and concatenates it into a SQL statement without parameterization or sanitization. An attacker can supply crafted input containing SQL metacharacters to break out of the intended query context.

Because the attack vector is network-based and requires no authentication or user interaction, exploitation can be automated. Public disclosure of the exploit detail through the GitHub CVE Issue Discussion lowers the technical barrier for attackers. Successful exploitation can result in unauthorized data reads, data modification, or chained attacks against backend infrastructure.

Root Cause

The root cause is the absence of prepared statements or input validation on the ID parameter inside /admin/member_update.php. The PHP code passes user-supplied input directly into a MySQL query string. This pattern enables classic SQL injection where attacker-controlled syntax becomes part of the executed query.

Attack Vector

An attacker sends a crafted HTTP request to the administrative endpoint with a malicious ID value. The injected payload modifies the WHERE clause or appends additional SQL statements. No credentials are needed if the endpoint is reachable, and the attack can be replayed remotely against any exposed deployment.

For exploitation specifics, refer to the VulDB entry #303551.

Detection Methods for CVE-2025-3337

Indicators of Compromise

• HTTP requests to /admin/member_update.php containing SQL metacharacters such as ', --, UNION, SELECT, or OR 1=1 in the ID parameter
• Unexpected database errors logged by the application or MySQL server tied to the member_update.php endpoint
• Anomalous outbound database traffic or data volumes following requests to the admin endpoint
• Unauthorized changes to member records or new administrative accounts created without an audit trail

Detection Strategies

• Deploy web application firewall (WAF) rules that inspect query string and POST body parameters submitted to /admin/member_update.php for SQL injection patterns
• Enable MySQL general query logging in staging or canary environments to identify queries built from untrusted input
• Correlate application access logs with database error logs to surface failed injection attempts

Monitoring Recommendations

• Monitor admin endpoints for repeated requests from a single source IP with varying ID parameter content
• Alert on HTTP 500 responses from /admin/member_update.php, which often indicate injection probing
• Track database user activity for unexpected INFORMATION_SCHEMA reads or UNION-based queries

How to Mitigate CVE-2025-3337

Immediate Actions Required

• Restrict network access to the /admin/ directory using IP allowlisting or VPN-only access until a patch is applied
• Audit the application source to replace string-concatenated SQL with parameterized queries using PDO or mysqli prepared statements
• Review database logs for evidence of prior exploitation and rotate credentials for any administrative accounts stored in the affected database

Patch Information

No official vendor patch is listed in the published advisories. Organizations running Adonesevangelista Online Restaurant Management System 1.0 should treat the deployment as end-of-life or apply source-level fixes. Monitor the GitHub CVE Issue Discussion and VulDB submission #551911 for vendor updates.

Workarounds

• Place the application behind a WAF with SQL injection signatures tuned for PHP query patterns
• Enforce input validation at the reverse proxy layer to reject non-numeric ID values before they reach PHP
• Run the application database account with least-privilege grants, removing FILE, CREATE, and DROP permissions where unnecessary
• Consider migrating to an actively maintained restaurant management platform if the vendor does not release a fix

# Configuration example: nginx rule to reject non-numeric ID values on the admin endpoint
location = /admin/member_update.php {
    if ($arg_id !~ "^[0-9]+$") {
        return 400;
    }
    include fastcgi_params;
    fastcgi_pass unix:/var/run/php-fpm.sock;
}
