CVE-2025-11603: Simple Food Ordering System SQLi Flaw

CVE-2025-11603 Overview

CVE-2025-11603 is a SQL injection vulnerability in code-projects Simple Food Ordering System 1.0. The flaw resides in the /editproduct.php script, where the Category request argument is concatenated into a backend SQL query without proper sanitization. An authenticated remote attacker can manipulate the parameter to alter query logic and read or modify database contents. The issue is tracked under CWE-89 (Improper Neutralization of Special Elements used in an SQL Command) and CWE-74 (Improper Neutralization). Public technical details have been disclosed through third-party vulnerability databases.

Critical Impact
Remote attackers with low privileges can inject arbitrary SQL into the Category parameter of editproduct.php, enabling unauthorized data access, modification, or further compromise of the application database.

Technical Details for CVE-2025-11603

Vulnerability Analysis

The vulnerability exists in the product editing workflow of the Simple Food Ordering System. The /editproduct.php endpoint accepts a Category parameter and incorporates it directly into a SQL statement executed against the backend database. Because the input is not parameterized or escaped, attacker-controlled SQL fragments are interpreted as part of the query.

Exploitation requires network access to the application and at least low-level authenticated privileges, consistent with the CVSS vector indicating user-level access (PR:L) and no user interaction. The impact spans confidentiality, integrity, and availability of database content, although each is rated low in scope. A public proof of concept has been referenced in third-party advisories, increasing the likelihood of opportunistic exploitation against exposed deployments.

Root Cause

The root cause is improper neutralization of user input before constructing a SQL statement. The editproduct.php handler does not use prepared statements or parameter binding for the Category argument. Standard SQL injection payloads using single quotes, UNION SELECT, or boolean-based conditions can therefore alter query behavior.

Attack Vector

An attacker authenticates to the application, then issues a crafted HTTP request to /editproduct.php with a malicious Category value. Typical injection payloads append additional clauses such as ' OR 1=1-- or UNION SELECT username,password FROM users-- to enumerate accounts or exfiltrate stored records. No specialized tooling is required; the attack can be reproduced with a browser or curl. See the GitHub CVE Issue #4 and VulDB entry #327925 for additional technical context.

Detection Methods for CVE-2025-11603

Indicators of Compromise

HTTP POST or GET requests to /editproduct.php containing SQL metacharacters such as ', --, UNION, SLEEP(, or OR 1=1 in the Category parameter.
Web server access logs showing anomalously long or URL-encoded Category values from a single source.
Database error messages referencing syntax errors originating from the editproduct.php workflow.
Unexpected modifications to product or user tables shortly after suspicious requests.

Detection Strategies

Deploy web application firewall (WAF) rules that inspect the Category parameter on /editproduct.php for SQL injection patterns.
Enable database query logging and alert on queries containing tautologies (1=1), UNION SELECT, or time-delay functions originating from the application service account.
Correlate authentication events with subsequent requests to editproduct.php to identify low-privilege accounts probing administrative endpoints.

Monitoring Recommendations

Forward web server, PHP error, and MySQL logs to a centralized analytics platform for retention and correlation.
Baseline normal Category values during legitimate product edits and alert on deviations such as non-alphanumeric content.
Track outbound database row counts to detect bulk data extraction attempts following injection.

How to Mitigate CVE-2025-11603

Immediate Actions Required

Restrict access to /editproduct.php to trusted administrative networks using IP allowlists or a reverse proxy until a code fix is applied.
Audit application accounts and revoke unnecessary privileges, since exploitation requires authenticated access (PR:L).
Review recent database activity for evidence of unauthorized reads or writes against product and user tables.
Deploy a WAF signature blocking SQL injection patterns on the Category parameter.

Patch Information

No official vendor patch has been published in the referenced advisories at the time of writing. Organizations using code-projects Simple Food Ordering System 1.0 should monitor the code-projects website and VulDB entry #327925 for fix availability. As a code-level remediation, replace inline query construction in editproduct.php with parameterized statements using mysqli prepared statements or PDO bound parameters, and apply server-side input validation that constrains Category to expected values.

Workarounds

Implement a reverse-proxy rule that rejects requests to /editproduct.php when the Category parameter contains characters outside [A-Za-z0-9 _-].
Move the application behind authenticated VPN access to reduce the exposed attack surface.
Apply database least-privilege by ensuring the application database user cannot read sensitive tables or execute administrative SQL.
