SQL injection vulnerability in admin/admin_catalog.php in e-topbiz Number Links 1 Php Script allows remote attackers to execute arbitrary SQL commands via the id parameter in an edit action.
A critical SQL injection vulnerability exists in the e-topbiz Number Links 1 Php Script, allowing attackers to remotely execute arbitrary SQL commands and potentially gain full control of the database and the underlying server. This vulnerability, exploitable through the admin/admin_catalog.php script, poses a significant risk of data breaches, system compromise, and denial-of-service attacks.
Step 1: Target Identification: The attacker identifies the vulnerable admin/admin_catalog.php script within the e-topbiz Number Links 1 Php Script installation. This is typically done through reconnaissance and vulnerability scanning.
Step 2: Payload Delivery: The attacker crafts a malicious SQL injection payload, designed to execute arbitrary SQL commands. This payload is embedded within the id parameter of an HTTP request to admin/admin_catalog.php with the edit action.
Step 3: Request Submission: The attacker submits the crafted HTTP request to the vulnerable server.
Step 4: Query Execution: The server receives the request and, due to the lack of input validation, directly incorporates the attacker's payload into an SQL query. The database server then executes this modified query.
Step 5: Command Execution/Data Exfiltration: Based on the injected SQL commands, the attacker can achieve various objectives, such as reading sensitive data (e.g., usernames, passwords), modifying data, or even executing operating system commands if the database server is configured to allow it. The attacker can also attempt to escalate privileges within the database or the underlying system.
The vulnerability stems from a failure to properly sanitize user-supplied input before incorporating it into an SQL query. Specifically, the id parameter within the admin/admin_catalog.php script, used in the edit action, is directly used in a database query without any input validation or escaping. This allows an attacker to inject malicious SQL code through this parameter. The root cause is a lack of input validation and parameterized queries, which are essential for preventing SQL injection attacks. The script directly concatenates user-controlled data into SQL statements, making it susceptible to malicious code injection. The absence of prepared statements or stored procedures further exacerbates the vulnerability.
While no specific APT groups are directly linked to this CVE, the nature of SQL injection makes it a common attack vector used by various threat actors, including those seeking to steal data, deface websites, or establish a foothold for further attacks. This vulnerability could be exploited by any attacker with basic SQL injection knowledge. CISA KEV status: Not listed.
Web application firewall (WAF) logs showing suspicious SQL injection attempts, such as the use of single quotes, double quotes, or SQL keywords like 'SELECT', 'UPDATE', 'INSERT', 'DELETE', 'UNION', 'OR', 'AND'.
Database server logs revealing unusual SQL queries, especially those containing user-supplied input and SQL keywords.
Network traffic analysis identifying suspicious HTTP requests to admin/admin_catalog.php with potentially malicious payloads in the id parameter.
File integrity monitoring detecting unauthorized modifications to the admin/admin_catalog.php file or other related files.
Intrusion detection systems (IDS) configured with signatures for SQL injection attacks.
Implement input validation on all user-supplied data, especially the id parameter. Sanitize the input by escaping special characters or using a whitelist approach.
Use parameterized queries or prepared statements to prevent SQL injection. This approach separates the SQL code from the user-supplied data, ensuring that the data is treated as data and not as executable code.
Upgrade to the latest version of the e-topbiz Number Links 1 Php Script, if available, which may include a patched version of the vulnerable code.
Apply a Web Application Firewall (WAF) to filter malicious requests and block SQL injection attempts.
Implement the principle of least privilege for database users. Restrict database user accounts to only the necessary permissions.
Regularly scan the web application for vulnerabilities using automated tools.
Monitor web server and database server logs for suspicious activity.
