SQL injection vulnerability in detail.asp in Site2Nite Business e-Listings allows remote attackers to execute arbitrary SQL commands via the ID parameter.
Site2Nite Business e-Listings suffers from a critical SQL injection vulnerability in its detail.asp file, allowing attackers to execute arbitrary SQL commands. This flaw permits complete database compromise, potentially leading to data theft, system takeover, and significant business disruption. Successful exploitation requires no authentication, posing a severe risk to any organization using the vulnerable software.
Step 1: Payload Delivery: The attacker crafts a malicious SQL injection payload. This payload is designed to execute arbitrary SQL commands when inserted into the ID parameter of the detail.asp file.
Step 2: Request Submission: The attacker sends an HTTP GET or POST request to detail.asp containing the crafted payload in the ID parameter (e.g., detail.asp?ID=1' UNION SELECT ... --).
Step 3: Query Execution: The vulnerable application receives the request and incorporates the attacker's payload directly into an SQL query without proper sanitization. The database server then executes this modified query.
Step 4: Data Manipulation: The injected SQL commands are executed by the database. The attacker can then perform actions such as retrieving sensitive data (e.g., usernames, passwords, customer information), modifying data, or even executing operating system commands if the database server is configured to allow it.
Step 5: Information Disclosure/System Compromise: The results of the malicious SQL commands are returned to the attacker, leading to data exfiltration or further exploitation, potentially leading to complete system compromise.
The vulnerability stems from a failure to properly sanitize user-supplied input provided through the ID parameter in the detail.asp file. The application directly incorporates this unsanitized input into an SQL query without any form of validation or escaping. This allows an attacker to inject malicious SQL code, altering the intended query logic. The root cause is a lack of input validation and parameterized queries, which are essential for preventing SQL injection attacks. The absence of these security measures allows attackers to manipulate the database's behavior, leading to unauthorized access and control.
While no specific APT groups are directly linked to this CVE, SQL injection is a common technique used by various threat actors, including those involved in data theft and ransomware campaigns. The ease of exploitation makes it attractive to a wide range of attackers. CISA KEV status is unlikely due to the age of the vulnerability, but it remains a significant risk.
Web server logs will show suspicious HTTP requests to detail.asp containing SQL injection payloads (e.g., ' OR '1'='1).
Database server logs will reveal unusual SQL queries, including those with unexpected syntax or commands.
Network traffic analysis can identify malicious HTTP requests with SQL injection payloads in the ID parameter.
Intrusion Detection Systems (IDS) and Web Application Firewalls (WAFs) can be configured to detect SQL injection attempts based on signature matching or behavioral analysis.
File integrity monitoring can detect changes to the detail.asp file, which might indicate compromise.
Implement input validation to strictly control the format and content of the ID parameter, rejecting or sanitizing any potentially malicious input.
Use parameterized queries or prepared statements to prevent SQL injection. This separates the SQL code from the user-supplied data, ensuring that user input is treated as data and not as executable code.
Apply the latest security patches for the Site2Nite Business e-Listings software.
Implement a Web Application Firewall (WAF) to filter malicious traffic and protect against SQL injection attacks.
Regularly scan the application for vulnerabilities using automated tools.
Review and harden the database server configuration, including disabling unnecessary features and applying security best practices.
Implement the principle of least privilege for database users, restricting their access to only the necessary resources.
