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. |

AI Powered Q&A
Can you explain this vulnerability to me?
CVE-2026-5579 is an SQL injection vulnerability found in CodeAstro Online Classroom version 1.0, specifically in the file /OnlineClassroom/updatedetailsfromfaculty.php. The issue arises from improper handling of the 'fname' parameter, which is embedded directly into SQL queries without proper sanitization or validation.
This flaw allows attackers to inject malicious SQL code remotely, manipulating database queries to gain unauthorized access, extract or modify data, delete information, or disrupt services.
Technical exploitation techniques include Boolean-based blind SQL injection, error-based SQL injection, and time-based blind SQL injection, demonstrated through various proof-of-concept payloads targeting the 'fname' parameter.
How can this vulnerability impact me? :
This vulnerability can have serious impacts including unauthorized access to sensitive data, data leakage, data modification or deletion, and full system compromise.
Attackers exploiting this flaw can disrupt normal service operations, potentially causing downtime or loss of business continuity.
- Unauthorized database access
- Data leakage
- Data modification or deletion
- Full system compromise
- Service disruption
How can this vulnerability be detected on my network or system? Can you suggest some commands?
This vulnerability can be detected by testing the vulnerable parameter `fname` in the file `/OnlineClassroom/updatedetailsfromfaculty.php` for SQL injection using various techniques such as Boolean-based blind, error-based, and time-based SQL injection.
Example payloads to test the `fname` parameter include:
- Boolean-based blind SQL injection using MySQL RLIKE operator.
- Error-based SQL injection exploiting MySQL error messages.
- Time-based blind SQL injection leveraging MySQL's SLEEP() function.
Testing can be automated using tools like sqlmap with crafted POST requests containing malicious `fname` values.
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 data conforms to expected formats.
- Minimize database user permissions, avoiding use of high-privilege accounts like root or admin for routine operations.
- Conduct regular security audits to detect and fix vulnerabilities promptly.
How does this vulnerability affect compliance with common standards and regulations (like GDPR, HIPAA)?:
The SQL injection vulnerability in CodeAstro Online Classroom 1.0 allows attackers to gain unauthorized access to the database, potentially leading to data leakage, modification, or deletion. Such unauthorized access and data compromise can result in violations of data protection regulations like GDPR and HIPAA, which mandate the protection of personal and sensitive information. Failure to secure systems against such vulnerabilities may lead to non-compliance with these standards, exposing organizations to legal and financial penalties.
