CVE-2025-6484: Online Shopping Store SQL Injection Flaw

CVE-2025-6484 Overview

CVE-2025-6484 is a SQL injection vulnerability in code-projects Online Shopping Store 1.0, distributed by Fabian. The flaw resides in the /action.php script, where the cat_id, brand_id, keyword, proId, and pid parameters are concatenated into SQL queries without sanitization [CWE-89]. Attackers can manipulate these parameters remotely to inject arbitrary SQL statements. The exploit details have been publicly disclosed, increasing the likelihood of opportunistic abuse against exposed deployments. The vulnerability is classified under improper neutralization of special elements in output used by a downstream component [CWE-74].

Critical Impact
Remote attackers with authenticated access can manipulate database queries through /action.php parameters, potentially exposing or modifying backend data in Online Shopping Store 1.0.

Affected Products

Fabian Online Shopping Store 1.0
/action.php endpoint processing cat_id, brand_id, keyword, proId, pid
Deployments using the unpatched code-projects PHP codebase

Technical Details for CVE-2025-6484

Vulnerability Analysis

The vulnerability exists in the request handling logic of /action.php within the Online Shopping Store 1.0 application. The script accepts user-controlled input through five parameters: cat_id, brand_id, keyword, proId, and pid. These values flow directly into SQL queries without prepared statements or input validation. An attacker can append SQL operators and clauses such as UNION SELECT to extract data from the underlying database. The flaw is reachable over the network and requires only minimal interaction with the application's product browsing functionality.

Root Cause

The root cause is improper neutralization of special elements used in an SQL command [CWE-89]. The PHP code concatenates HTTP request parameters into query strings rather than using parameterized queries or an ORM with bound variables. This pattern is common in legacy PHP applications that rely on mysqli_query or similar functions with string interpolation.

Attack Vector

The attack is delivered over HTTP to the /action.php endpoint. An authenticated attacker submits crafted values in any of the five vulnerable parameters. Successful injection allows reading arbitrary database tables, modifying records, or enumerating schema information. Public proof-of-concept submissions are referenced in the GitHub PoC Issue #5 and GitHub PoC Issue #6 repositories.

No verified exploit code is published in the advisory references. Refer to the VulDB entry #313592 for additional technical context.

Detection Methods for CVE-2025-6484

Indicators of Compromise

HTTP requests to /action.php containing SQL metacharacters such as ', --, UNION, or SELECT in cat_id, brand_id, keyword, proId, or pid parameters
Web server access logs showing unusually long or encoded query strings targeting the affected endpoint
Database error messages or anomalous query patterns in MySQL logs originating from the application service account

Detection Strategies

Deploy web application firewall (WAF) rules that flag SQL injection signatures on the /action.php URI
Enable database query logging and alert on unexpected UNION, INFORMATION_SCHEMA, or stacked statements
Correlate web traffic with database telemetry to identify parameter tampering patterns

Monitoring Recommendations

Forward web server and database logs to a centralized SIEM for retention and correlation
Baseline normal request volume to /action.php and alert on deviations
Monitor outbound database connections for data exfiltration following suspicious requests

How to Mitigate CVE-2025-6484

Immediate Actions Required

Restrict network access to the Online Shopping Store 1.0 application until a fix is applied
Audit /action.php and rewrite affected queries to use parameterized statements
Review web server logs for prior exploitation attempts targeting the listed parameters

Patch Information

No official vendor patch is referenced in the NVD entry or VulDB submissions at the time of publication. Operators should monitor the Code Projects Resource Hub for updated releases and apply source-level fixes to neutralize the affected parameters.

Workarounds

Place the application behind a WAF with SQL injection rule sets enabled
Implement server-side input validation that rejects non-numeric values for cat_id, brand_id, proId, and pid
Apply least-privilege database account permissions to limit the impact of successful injection

bash

# Example WAF rule (ModSecurity) blocking SQLi patterns on /action.php
SecRule REQUEST_URI "@beginsWith /action.php" \
    "id:1006484,phase:2,deny,status:403,\
    chain,msg:'Possible SQLi against CVE-2025-6484'"
    SecRule ARGS:cat_id|ARGS:brand_id|ARGS:keyword|ARGS:proId|ARGS:pid \
