A security vulnerability has been detected in itsourcecode Document Management System 1.0. Affected is an unknown function of the file /edtlbls.php. The manipulation of the argument field1 leads to sql injection. The attack may be initiated remotely. The exploit has been disclosed publicly and may be used.
itsourcecode Document Management System 1.0 is vulnerable to a critical SQL injection flaw in /edtlbls.php, allowing for remote code execution. This vulnerability, triggered by manipulating the field1 parameter, enables attackers to potentially compromise the database and gain unauthorized access to sensitive information, leading to a severe data breach risk.
Step 1: Payload Delivery: The attacker crafts a malicious SQL injection payload designed to exploit the vulnerability in the field1 parameter of /edtlbls.php. This payload is designed to manipulate the SQL query executed by the application.
The vulnerability stems from insufficient input validation and sanitization of the field1 parameter within the /edtlbls.php file. The application likely directly incorporates user-supplied input from field1 into an SQL query without proper escaping or filtering. This allows an attacker to inject malicious SQL code, altering the intended query logic. The root cause is a failure to implement parameterized queries or to properly escape special characters within the user-provided input before it is used in the SQL statement. This lack of secure coding practices allows an attacker to execute arbitrary SQL commands, such as retrieving sensitive data, modifying database contents, or even executing operating system commands if the database server is configured to allow it.
While no specific APTs are directly linked to this CVE at this time, the public availability of the exploit and the severity of the vulnerability make it attractive to a wide range of threat actors, including those seeking to steal data or establish a foothold within the target network. The lack of specific attribution makes it difficult to pinpoint specific actors. CISA KEV status: Not Applicable (as of the provided information, no KEV status is available).
Network Intrusion Detection Systems (NIDS) should be configured to detect SQL injection attempts. Look for suspicious patterns in HTTP requests, such as the use of single quotes, double quotes, semicolons, and other SQL-specific keywords in the field1 parameter.
Web Application Firewalls (WAFs) can be deployed to filter malicious requests. Configure the WAF to block requests containing known SQL injection payloads.
Review web server access logs for unusual activity, such as a high volume of requests to /edtlbls.php or requests containing suspicious strings in the field1 parameter.
Database activity monitoring can be used to detect unusual database queries. Monitor for queries that are not expected or that contain suspicious patterns.
Implement 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.
Sanitize all user-supplied input by escaping special characters or using a whitelist of allowed characters. This prevents malicious code from being injected into the SQL query.
Regularly update the itsourcecode Document Management System to the latest version, which may include patches for this vulnerability.
Apply the principle of least privilege to database accounts. Limit the permissions of the database user account used by the application to only the necessary operations.
Conduct regular security audits and penetration testing to identify and address vulnerabilities.
