Exploitability
| CWE ID | Description |
|---|---|
| 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. |
| 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. |

AI Powered Q&A
Can you explain this vulnerability to me?
CVE-2026-4842 is a critical SQL injection vulnerability found in the Online Enrollment System version 1.0, specifically in the file "/sms/grades/index.php?view=edit&id=1". The issue arises because the 'deptid' parameter is improperly handled and directly used in SQL queries without proper input validation or sanitization.
Attackers can exploit this vulnerability remotely by injecting malicious SQL code through the 'deptid' parameter, which allows unauthorized access to the database, data leakage, modification, deletion, or even full system compromise. No authentication or authorization is required to carry out this attack.
The vulnerability was demonstrated using a time-based blind SQL injection technique targeting MySQL versions 5.0.12 and above, confirming the exploitability of the 'deptid' parameter.
How can this vulnerability impact me? :
This vulnerability can have severe impacts including unauthorized access to sensitive data, data leakage, unauthorized data modification or deletion, and potential full system compromise.
Exploitation of this flaw can disrupt business continuity and compromise system security, as attackers can manipulate the database remotely without needing any authentication.
How can this vulnerability be detected on my network or system? Can you suggest some commands?
This vulnerability can be detected by testing the 'deptid' parameter for SQL injection flaws, particularly in POST requests to "/sms/grades/controller.php?action=edit".
A common method is to use automated tools like sqlmap to confirm exploitability by injecting payloads that cause time delays (e.g., SLEEP(5)) to verify blind SQL injection.
- Use sqlmap with a command similar to: sqlmap -u "http://target/sms/grades/controller.php?action=edit" --data="deptid=1" --method=POST --technique=T --dbms=MySQL
- Manually test by sending crafted POST requests with SQL payloads in the 'deptid' parameter to observe abnormal delays or error messages.
What immediate steps should I take to mitigate this vulnerability?
Immediate mitigation steps include:
- Implement prepared statements with parameter binding to separate SQL code from user input.
- Apply strict input validation and filtering to ensure the 'deptid' parameter only accepts expected formats.
- Minimize database user permissions by avoiding the use of high-privilege accounts such as root or admin for routine database operations.
- Conduct regular security audits to detect and address vulnerabilities promptly.
How does this vulnerability affect compliance with common standards and regulations (like GDPR, HIPAA)?:
The SQL injection vulnerability in the Online Enrollment System allows unauthorized access, data leakage, and data modification without authentication. Such unauthorized access and potential data breaches can lead to non-compliance with common standards and regulations like GDPR and HIPAA, which mandate the protection of personal and sensitive data.
Failure to properly secure the system against this vulnerability could result in exposure of personal data, violating data protection requirements and potentially leading to legal and financial penalties under these regulations.
