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-2026-4235 is a critical SQL injection vulnerability found in the itsourcecode Online Enrollment System version 1.0, specifically in the /sms/login.php file.'}, {'type': 'paragraph', 'content': "The vulnerability arises because the 'user_email' parameter is improperly handled without adequate input validation or sanitization, allowing attackers to inject malicious SQL code."}, {'type': 'paragraph', 'content': 'This flaw enables unauthorized database access, data leakage, data tampering, and potentially full system control or service disruption.'}, {'type': 'paragraph', 'content': 'Exploitation can be performed remotely without any authentication, making it highly accessible to attackers.'}, {'type': 'paragraph', 'content': 'Technical details include multiple SQL injection techniques such as Boolean-based blind, error-based, and time-based blind SQL injection demonstrated via proof-of-concept payloads.'}] [1, 2, 3]
How can this vulnerability impact me? :
This vulnerability can lead to unauthorized access to the database, allowing attackers to view, modify, or delete sensitive information.
It threatens the confidentiality, integrity, and availability of the system.
Attackers can exploit this flaw to manipulate data, disrupt services, and potentially gain full control over the affected system.
Since the exploit is publicly available and requires no authentication, the risk of attack is significantly increased.
This can result in severe security breaches and business continuity issues.
How does this vulnerability affect compliance with common standards and regulations (like GDPR, HIPAA)?:
I don't know
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 'user_email' parameter in POST requests to the /sms/login.php file for SQL injection flaws."}, {'type': 'paragraph', 'content': "Automated tools like sqlmap can be used to confirm the vulnerability by attempting SQL injection attacks on the 'user_email' parameter."}, {'type': 'list_item', 'content': 'Use sqlmap with a command similar to: sqlmap -u "http://target/sms/login.php" --data="[email protected]" --risk=3 --level=5 --batch'}, {'type': 'list_item', 'content': "Perform manual testing using Boolean-based blind SQL injection payloads, error-based SQL injection payloads, or time-based blind SQL injection payloads targeting the 'user_email' parameter."}, {'type': 'list_item', 'content': 'Use Google dorking to identify potentially vulnerable targets by searching for: inurl:sms/login.php'}] [2, 3]
What immediate steps should I take to mitigate this vulnerability?
[{'type': 'paragraph', 'content': 'Immediate remediation is necessary to secure the system and maintain data integrity.'}, {'type': 'list_item', 'content': 'Replace the affected software with an alternative product if possible.'}, {'type': 'list_item', 'content': 'Implement prepared statements with parameter binding to separate SQL code from user input.'}, {'type': 'list_item', 'content': 'Apply strict input validation and filtering to ensure inputs conform to expected formats.'}, {'type': 'list_item', 'content': "Minimize database user permissions, avoiding use of high-privilege accounts like 'root' or 'admin' for routine operations."}, {'type': 'list_item', 'content': 'Conduct regular security audits to detect and fix vulnerabilities promptly.'}] [1, 3, 2]
