CVE-2025-11558: Fabian E-commerce Website SQLi Vulnerability

CVE-2025-11558 Overview

CVE-2025-11558 is a SQL injection vulnerability in code-projects E-Commerce Website 1.0. The flaw resides in the /pages/user_index_search.php script, where the Search parameter is concatenated into a database query without proper sanitization. Remote attackers can inject arbitrary SQL statements over the network without authentication. The exploit details have been published, increasing the likelihood of opportunistic abuse against exposed deployments. The weakness is tracked under CWE-89 (Improper Neutralization of Special Elements used in an SQL Command) and CWE-74 (Improper Neutralization of Special Elements in Output Used by a Downstream Component).

Critical Impact
Unauthenticated remote attackers can manipulate the Search parameter to read, modify, or destroy backend database contents.

Technical Details for CVE-2025-11558

Vulnerability Analysis

The vulnerability is a classic SQL injection flaw in the search functionality of code-projects E-Commerce Website 1.0. The application accepts user input through the Search parameter submitted to /pages/user_index_search.php and incorporates it directly into a SQL query string. Because the parameter is neither parameterized nor escaped, an attacker can break out of the intended query context and append additional SQL syntax.

The attack requires no authentication and no user interaction. An adversary only needs network access to the vulnerable PHP endpoint. Public exploit details mean that automated scanners and opportunistic attackers can reproduce the issue with minimal effort.

Root Cause

The root cause is improper neutralization of special elements in a SQL command [CWE-89]. The Search argument is interpolated directly into a query without prepared statements or input validation. Any single quote, comment marker, or UNION clause submitted by an attacker is interpreted as SQL syntax rather than literal data.

Attack Vector

An attacker sends a crafted HTTP request to /pages/user_index_search.php with a malicious Search parameter. Typical payloads use boolean-based, time-based, or UNION-based techniques to extract data from the underlying MySQL database. Successful exploitation enables enumeration of database tables, exfiltration of customer records, manipulation of order data, or in some configurations, file system access through database functions such as INTO OUTFILE.

No verified proof-of-concept code is available from the references provided. Refer to the GitHub CVE Report and VulDB entry #327718 for additional technical context.

Detection Methods for CVE-2025-11558

Indicators of Compromise

HTTP requests to /pages/user_index_search.php containing SQL metacharacters in the Search parameter, such as ', --, UNION SELECT, or SLEEP(.
Unusual database error messages returned in HTTP responses from the search endpoint.
Spikes in query execution time or anomalous result set sizes from the e-commerce database server.
Web server access logs showing automated scanner user agents probing the search endpoint.

Detection Strategies

Deploy web application firewall (WAF) rules that flag SQL injection signatures targeting the Search query parameter.
Enable database query logging and alert on queries containing tautologies such as OR 1=1 or stacked statements originating from the e-commerce application.
Review historical access logs for the user_index_search.php path to identify retroactive exploitation attempts.

Monitoring Recommendations

Correlate web access logs with database audit logs to identify request-to-query patterns indicative of injection.
Monitor outbound traffic from the database server for unexpected data egress that may indicate exfiltration.
Alert on authentication anomalies and privilege changes within the application database following suspicious search requests.

How to Mitigate CVE-2025-11558

Immediate Actions Required

Restrict public access to /pages/user_index_search.php until a patched version is available, using network controls or authentication gates.
Apply WAF rules that block common SQL injection patterns submitted to the Search parameter.
Audit the application database for unauthorized modifications, new administrative accounts, or evidence of data exfiltration.
Rotate database credentials and review service account privileges following any suspected compromise.

Patch Information

No official vendor patch has been published in the references provided. code-projects E-Commerce Website 1.0 is a small open-source project, and organizations using this codebase should remediate the vulnerable query directly. Replace the dynamic SQL in user_index_search.php with a prepared statement using PDO or MySQLi parameter binding. Track updates through the code-projects website and the VulDB advisory.

Workarounds

Implement server-side input validation that rejects non-alphanumeric characters in the Search parameter where business logic allows.
Apply the principle of least privilege to the database user account used by the application, removing FILE, DROP, and administrative permissions.
Place the application behind a reverse proxy with virtual patching rules for SQL injection until the source code is fixed.
