SQL injection vulnerability in admin/login.php in E-topbiz Online Store 1.0 allows remote attackers to execute arbitrary SQL commands via the user parameter (aka username field). NOTE: some of these details are obtained from third party information.
E-topbiz Online Store 1.0 is vulnerable to a critical SQL injection flaw, allowing attackers to execute arbitrary SQL commands. This can lead to complete database compromise, including sensitive data theft and potential server takeover, impacting the confidentiality, integrity, and availability of the affected system.
Step 1: Payload Delivery: The attacker crafts a malicious SQL injection payload and inserts it into the user parameter of a POST request to admin/login.php. This payload is designed to manipulate the SQL query used for authentication.
Step 2: Request Submission: The attacker submits the crafted request to the vulnerable web server.
Step 3: Query Execution: The admin/login.php script receives the request and, without proper sanitization, incorporates the attacker's input (the payload) directly into an SQL query. For example, the query might look like: SELECT * FROM users WHERE username = '$user_input' AND password = '$password_input'; where $user_input is controlled by the attacker.
Step 4: Payload Interpretation: The database server interprets the injected SQL code as part of the query. The attacker can use the payload to bypass authentication, extract data, or even execute arbitrary commands on the database server.
Step 5: Data Exfiltration/Privilege Escalation: Depending on the payload, the attacker can then retrieve sensitive information (e.g., usernames, passwords, credit card details), modify data, or gain administrative access to the database and potentially the underlying server.
The vulnerability stems from a lack of proper input validation and sanitization of the user parameter within the admin/login.php script. Specifically, the application directly incorporates user-supplied input into SQL queries without escaping special characters. This allows an attacker to inject malicious SQL code, altering the query's intended behavior. The root cause is a failure to implement parameterized queries or other safe methods of handling user input when constructing SQL statements. The absence of prepared statements and proper input validation allows for direct manipulation of the database queries, leading to unauthorized access and control.
While no specific APTs are definitively linked to this specific CVE, the nature of SQL injection makes it a common technique used by various threat actors, including those seeking financial gain (e.g., data theft, ransomware) and those conducting espionage. This vulnerability is not listed in the CISA KEV database, but the underlying vulnerability type (SQL injection) is frequently targeted by malicious actors.
Web server logs showing unusual POST requests to admin/login.php with suspicious characters in the user parameter (e.g., single quotes, semicolons, comments).
Database server logs indicating unexpected queries or errors related to SQL syntax.
Network traffic analysis revealing unusual HTTP POST requests containing SQL injection payloads.
Intrusion Detection/Prevention Systems (IDS/IPS) configured to detect SQL injection attempts.
File integrity monitoring detecting changes to admin/login.php or other related files.
Implement parameterized queries or prepared statements to prevent SQL injection. This separates the SQL code from the user-supplied data.
Thoroughly validate and sanitize all user input, especially input used in SQL queries. Escape special characters appropriately.
Apply the latest security patches for E-topbiz Online Store 1.0 or upgrade to a more secure version.
Implement a Web Application Firewall (WAF) to filter malicious requests.
Regularly scan the web application for vulnerabilities using automated tools.
Enforce the principle of least privilege for database users. Limit database user accounts' access to only the necessary tables and operations.
Review and harden the web server configuration to minimize attack surface.
