CVE-2025-8018: Food Ordering Review System SQLi Flaw

CVE-2025-8018 Overview

CVE-2025-8018 is a SQL injection vulnerability in code-projects Food Ordering Review System 1.0 by Carmelo. The flaw resides in the /user/reservation_page.php script, where the reg_Id parameter is passed to a database query without proper sanitization. An authenticated remote attacker can manipulate this parameter to inject arbitrary SQL statements. The vendor advisory notes that additional parameters in the same file may also be affected. Public disclosure of exploitation details has occurred, increasing the risk of opportunistic attacks against exposed deployments.

Critical Impact
Remote attackers with low-privilege access can manipulate database queries through the reg_Id parameter, potentially exposing or altering reservation and user data stored in the application.

Technical Details for CVE-2025-8018

Vulnerability Analysis

The vulnerability is classified under [CWE-74] (Improper Neutralization of Special Elements in Output Used by a Downstream Component). The reservation_page.php endpoint accepts a reg_Id parameter and concatenates it directly into a SQL query executed against the application database. Because user-controlled input is not parameterized or escaped, an attacker can break out of the intended query context and append arbitrary SQL clauses. The attack requires only low-privilege authenticated access and can be launched over the network with no user interaction. According to the EPSS data, exploitation probability remains low, but public disclosure of the technique raises the practical risk for internet-facing instances.

Root Cause

The root cause is the absence of prepared statements or input validation on the reg_Id parameter inside reservation_page.php. The application trusts client-supplied input and embeds it directly into a database query string. This violates the principle of separating code from data and enables query manipulation by any user who can reach the endpoint.

Attack Vector

An attacker sends a crafted HTTP request to /user/reservation_page.php with a malicious payload in the reg_Id parameter. The injected SQL is evaluated by the backend database, allowing the attacker to read unauthorized data, modify reservations, or enumerate the schema. Vendor notes indicate that other parameters in the same script may share the same flaw, expanding the attack surface beyond reg_Id.

No verified proof-of-concept code is published in the referenced sources. Technical details are tracked in the VulDB Vulnerability Analysis #317221 and GitHub CVE Issue Discussion.

Detection Methods for CVE-2025-8018

Indicators of Compromise

HTTP requests to /user/reservation_page.php containing SQL metacharacters such as ', --, UNION, SELECT, or OR 1=1 in the reg_Id parameter.
Unexpected database errors or verbose SQL exception messages returned to clients from the reservation page.
Anomalous outbound data volumes from the web application server following requests to the reservation endpoint.

Detection Strategies

Deploy web application firewall (WAF) rules that inspect query and POST parameters on reservation_page.php for SQL injection patterns.
Review database query logs for unusual SELECT statements referencing reservation tables outside normal application flows.
Correlate authentication logs with reservation page access to identify low-privilege accounts performing schema enumeration.

Monitoring Recommendations

Enable verbose access logging on the web server and forward logs to a centralized analytics platform for query parameter inspection.
Alert on repeated 500-level responses from reservation_page.php, which often indicate failed injection attempts.
Monitor for new or modified rows in user and reservation tables that were not initiated through the standard application workflow.

How to Mitigate CVE-2025-8018

Immediate Actions Required

Restrict access to the Food Ordering Review System to trusted networks until a vendor patch is applied.
Audit all references to reg_Id and adjacent parameters in reservation_page.php and refactor them to use parameterized queries.
Rotate database credentials and review audit logs for evidence of injection attempts against the reservation endpoint.

Patch Information

No official vendor patch is referenced in the available advisories. Operators should consult the Code Projects Security Resources page for vendor updates and track the VulDB entry #317221 for remediation status. Until a fix is released, administrators must apply application-layer mitigations.

Workarounds

Replace dynamic SQL with prepared statements using PDO or mysqli bound parameters for every parameter consumed by reservation_page.php.
Enforce server-side input validation to allow only expected numeric values for the reg_Id parameter.
Apply a WAF rule that blocks SQL metacharacters in requests to the reservation endpoint while a code fix is developed.
Run the application database account with least privilege so a successful injection cannot reach administrative tables.

bash

# Example ModSecurity rule to block SQLi attempts against the reservation endpoint
SecRule REQUEST_URI "@contains /user/reservation_page.php" \
  "id:1008018,phase:2,deny,status:403,\
   chain,msg:'CVE-2025-8018 SQLi attempt on reg_Id'"
  SecRule ARGS:reg_Id "@rx (?i)(union|select|insert|update|delete|--|';|/\*)" \
    "t:none,t:urlDecodeUni"
