CVE-2025-0297: Online Book Shop SQL Injection Vulnerability

CVE-2025-0297 Overview

CVE-2025-0297 is a SQL injection vulnerability in code-projects Online Book Shop 1.0. The flaw resides in the /detail.php script, where the id parameter is passed directly into a database query without proper sanitization. Attackers can manipulate this parameter to inject arbitrary SQL statements and interact with the backend database. The vulnerability is remotely exploitable over the network and requires low privileges. Public disclosure of the exploit technique means opportunistic attackers can weaponize this issue against exposed installations. The weakness is classified under CWE-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component (Injection).

Critical Impact
Remote attackers can inject SQL statements through the id parameter of /detail.php to read, modify, or extract data from the backend database of Online Book Shop 1.0.

Affected Products

code-projects Online Book Shop 1.0
Deployments referencing the vulnerable /detail.php endpoint
Web applications sharing the same unsanitized query pattern

Technical Details for CVE-2025-0297

Vulnerability Analysis

The vulnerability lives in the /detail.php script of Online Book Shop 1.0. The script accepts an id parameter through an HTTP request and concatenates it into a SQL query without parameterization or input validation. An attacker supplying crafted values for id can break out of the intended query context and append arbitrary SQL clauses. Successful exploitation allows enumeration of database schema, extraction of stored records such as user credentials and order data, and modification of database contents. Because the endpoint is reachable over the network with only low privileges required, the attack surface includes any exposed instance of the application. Public availability of exploit details lowers the effort required to reproduce the attack.

Root Cause

The root cause is improper neutralization of user-controlled input passed to a SQL interpreter. The application constructs SQL statements by concatenating the raw id parameter, rather than using prepared statements or parameterized queries. This aligns with the CWE-74 injection weakness family and specifically maps to SQL injection.

Attack Vector

Exploitation occurs remotely over HTTP. An attacker issues a request to /detail.php with a malicious value in the id query parameter. No user interaction is required, and the attack complexity is low. Refer to the GitHub Gist exploit reference and the VulDB CVE analysis for reproduction details.

Because verified exploit code is not reproduced here, refer to the VulDB entry #290446 for the disclosed payload structure.

Detection Methods for CVE-2025-0297

Indicators of Compromise

HTTP requests to /detail.php containing SQL metacharacters such as single quotes, UNION, SELECT, --, or /* in the id parameter.
Web server logs showing unusually long or encoded id values, or repeated requests iterating through injection payloads.
Database error messages returned to clients or logged, indicating malformed SQL syntax originating from detail.php.
Outbound database queries retrieving large volumes of records from tables not associated with normal book detail lookups.

Detection Strategies

Deploy web application firewall (WAF) rules that inspect the id parameter on /detail.php for SQL injection signatures.
Enable database query logging and alert on anomalous queries originating from the application's database user account.
Correlate web access logs with database audit logs to detect injection attempts that reach the SQL layer.

Monitoring Recommendations

Monitor for spikes in 500 responses or database error patterns tied to requests against /detail.php.
Track authenticated session activity for low-privilege accounts issuing crafted requests to product detail endpoints.
Alert on file system or process activity indicating post-exploitation behavior such as web shell writes into web-accessible directories.

How to Mitigate CVE-2025-0297

Immediate Actions Required

Restrict public exposure of Online Book Shop 1.0 instances until a fix is applied, using network ACLs or reverse proxy authentication.
Deploy WAF signatures blocking SQL injection payloads targeting the id parameter on /detail.php.
Review web and database logs for evidence of prior exploitation, focusing on the disclosure window from January 2025 onward.
Rotate credentials and secrets that may have been exposed if the database was accessed.

Patch Information

No vendor advisory or official patch has been published in the referenced sources. Consult the code-projects resource hub for vendor updates. Until a fix is released, code owners maintaining forks of this project should refactor /detail.php to use parameterized queries and validate the id parameter as a strict integer type.

Workarounds

Modify /detail.php to cast the id parameter to an integer before use, for example $id = (int)$_GET['id'];.
Replace concatenated SQL with prepared statements using PDO or MySQLi with bound parameters.
Restrict the database account used by the application to least-privilege read access on required tables only.
Place the application behind a WAF configured with OWASP Core Rule Set SQL injection rules.

bash
