How the Exploit Works
The vulnerability, as described, allows an attacker to leverage Blind SQL Injection techniques. SQL Injection vulnerabilities occur when an application fails to properly sanitize user-supplied input before incorporating it into an SQL query. In this case, the application is failing to neutralize special elements used in an SQL command.
A Blind SQL Injection differs from a traditional SQL Injection in that the results of the attack are not visible to the attacker. Instead, the attacker is able to reconstruct the database structure by sending payloads and observing the application’s response and the time it takes to respond.
Conceptual Example Code
Here’s a conceptual example of how the vulnerability might be exploited:
POST /login HTTP/1.1
Host: vulnerable-eron-crm.com
Content-Type: application/x-www-form-urlencoded
username=admin' AND 1=(SELECT CASE WHEN (1=1) THEN 1 ELSE 0 END FROM dual) AND '1'='1&password=In this example, the attacker is attempting to log in using the ‘admin’ username. The SQL statement following the username is a conditional statement that will always evaluate to true (1=1). If the application is vulnerable, it will process this statement as part of the SQL query, potentially allowing the attacker to log in as the ‘admin’ user.
Mitigation
The vendor has yet to release a patch for this vulnerability. Until a patch is available, it is recommended that organizations use a Web Application Firewall (WAF) or an Intrusion Detection System (IDS) as a temporary mitigation. These systems can help detect and block SQL Injection attacks.
Remember that while WAFs and IDS systems serve as good temporary solutions, they are not substitutes for secure coding practices. Always sanitize and validate user inputs to prevent SQL Injection attacks.
