Exploitability
| CWE ID | Description |
|---|---|
| CWE-74 | The product constructs all or part of a command, data structure, or record using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify how it is parsed or interpreted when it is sent to a downstream component. |
| CWE-89 | The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data. |

Can you explain this vulnerability to me?
[{'type': 'paragraph', 'content': 'CVE-2026-4223 is a critical SQL injection vulnerability found in itsourcecode Payroll Management System version 1.0, specifically affecting the /manage_employee.php file.'}, {'type': 'paragraph', 'content': 'The vulnerability arises from improper handling of the "ID" parameter, which allows an attacker to manipulate this argument to inject malicious SQL code.'}, {'type': 'paragraph', 'content': "This flaw is due to the lack of input validation and sanitization on the 'id' parameter, enabling attackers to perform unauthorized database operations without authentication."}, {'type': 'paragraph', 'content': 'The exploit is publicly available and can be executed remotely, making the attack vector highly accessible.'}] [1, 2, 3]
How can this vulnerability impact me? :
This SQL injection vulnerability can impact the confidentiality, integrity, and availability of the Payroll Management System.
Attackers can gain unauthorized access to the database, leak sensitive data, tamper with or modify data, and potentially gain full control over the system.
It can also cause service interruptions, threatening business continuity and system security.
Exploitation requires no authentication and can be performed remotely, increasing the risk and ease of attack.
How does this vulnerability affect compliance with common standards and regulations (like GDPR, HIPAA)?:

How can this vulnerability be detected on my network or system? Can you suggest some commands?
[{'type': 'paragraph', 'content': "The vulnerability can be detected by testing the /manage_employee.php file for SQL injection via the 'id' parameter. One approach is to use automated tools like sqlmap to test for SQL injection by targeting the vulnerable URL."}, {'type': 'list_item', 'content': 'Use sqlmap with a command such as: sqlmap -u "http://target/manage_employee.php?id=1" --dbs to check for SQL injection vulnerabilities.'}, {'type': 'list_item', 'content': "Perform manual testing by injecting SQL payloads into the 'id' parameter, for example: id=(SELECT (CASE WHEN (7937=7937) THEN 1 ELSE (SELECT 1707 UNION SELECT 4388) END)) to observe if the application behaves differently."}, {'type': 'list_item', 'content': 'Use Google dorking with the query "inurl:manage_employee.php" to identify potentially vulnerable targets on your network or externally.'}] [1, 3]
What immediate steps should I take to mitigate this vulnerability?
[{'type': 'paragraph', 'content': "Immediate mitigation steps include implementing proper input validation and sanitization on the 'id' parameter to prevent SQL injection."}, {'type': 'list_item', 'content': 'Use prepared statements and parameterized queries to separate SQL code from user input.'}, {'type': 'list_item', 'content': "Apply strict input filtering to ensure that the 'id' parameter only accepts expected formats, such as numeric values."}, {'type': 'list_item', 'content': 'Minimize database user permissions by avoiding the use of high-privilege accounts for routine database operations.'}, {'type': 'list_item', 'content': 'Conduct regular security audits and code reviews to identify and fix vulnerabilities promptly.'}, {'type': 'paragraph', 'content': 'If possible, replace the affected component with an alternative product that is not vulnerable.'}] [1, 3]
