CVE-2025-10842: Online Bidding System SQLi Vulnerability

CVE-2025-10842 Overview

A SQL Injection vulnerability has been identified in code-projects Online Bidding System version 1.0. The vulnerability exists in an unknown function within the file /administrator/wew.php, where improper handling of the ID argument allows attackers to inject malicious SQL queries. This vulnerability can be exploited remotely without authentication, and a public exploit is now available.

Critical Impact
Remote attackers can manipulate database queries through the vulnerable ID parameter, potentially leading to unauthorized data access, data manipulation, or complete database compromise.

Technical Details for CVE-2025-10842

Vulnerability Analysis

This SQL Injection vulnerability stems from improper input validation in the administrative interface of the Online Bidding System. The affected endpoint /administrator/wew.php accepts user-supplied input via the ID parameter without adequate sanitization or parameterized query implementation. When an attacker manipulates this parameter with crafted SQL syntax, the application directly incorporates the malicious input into database queries, allowing unauthorized database operations.

The vulnerability is categorized under CWE-74 (Improper Neutralization of Special Elements in Output Used by a Downstream Component), indicating that the application fails to properly neutralize special characters before passing data to the SQL interpreter.

Root Cause

The root cause of this vulnerability is insufficient input validation and lack of parameterized queries in the /administrator/wew.php file. The application directly concatenates user-controlled input from the ID parameter into SQL statements without proper escaping or sanitization. This architectural flaw allows attackers to break out of the intended query context and execute arbitrary SQL commands against the underlying database.

Attack Vector

The attack can be initiated remotely over the network without requiring authentication. An attacker can craft malicious HTTP requests targeting the /administrator/wew.php endpoint, manipulating the ID parameter to inject SQL payloads. The vulnerability is network-accessible, meaning any attacker with access to the web application can potentially exploit it.

The exploitation technique involves injecting SQL metacharacters and commands through the ID parameter. Depending on the database backend and application configuration, attackers may be able to extract sensitive data, modify database records, bypass authentication mechanisms, or in some cases achieve command execution on the underlying server.

Detection Methods for CVE-2025-10842

Indicators of Compromise

HTTP requests to /administrator/wew.php containing SQL metacharacters such as single quotes ('), double dashes (--), or UNION statements in the ID parameter
Unusual database error messages in application logs indicating malformed SQL queries
Unexpected database query patterns or elevated database load from the web application
Web server access logs showing repeated requests to the vulnerable endpoint with varying ID parameter values

Detection Strategies

Deploy Web Application Firewall (WAF) rules to detect and block SQL injection patterns in requests to /administrator/wew.php
Implement application-layer logging to capture all requests containing suspicious characters in the ID parameter
Monitor database query logs for anomalous queries originating from the web application
Configure intrusion detection systems (IDS) to alert on SQL injection signatures in HTTP traffic

Monitoring Recommendations

Enable verbose logging on the web server to capture full request parameters for forensic analysis
Set up real-time alerting for database errors that may indicate SQL injection attempts
Monitor for data exfiltration patterns such as unusual outbound data transfers from the database server
Implement file integrity monitoring on the /administrator/ directory to detect unauthorized modifications

How to Mitigate CVE-2025-10842

Immediate Actions Required

Restrict access to the /administrator/wew.php endpoint using IP-based access controls or authentication
Deploy a Web Application Firewall with SQL injection protection rules
If possible, disable or remove the vulnerable endpoint until a patch is available
Review application logs for any signs of prior exploitation

Patch Information

No official vendor patch has been identified for this vulnerability at the time of publication. Organizations should contact the vendor code-projects for remediation guidance. Monitor the VulDB entry for updates on available fixes.

Workarounds

Implement parameterized queries or prepared statements in the application code to prevent SQL injection
Apply input validation to sanitize the ID parameter, allowing only expected numeric values
Use a Web Application Firewall to filter malicious SQL injection payloads
Restrict network access to the administrative interface to trusted IP addresses only
Consider taking the affected application offline if it processes sensitive data until a proper fix is implemented

# Example: Apache .htaccess restriction for administrator directory
<Directory "/var/www/html/administrator">
    Order Deny,Allow
    Deny from all
