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-2026-7743 is a SQL injection vulnerability found in CodeAstro Online Classroom 1.0, specifically in the '/OnlineClassroom/studentdetails' file. The vulnerability occurs due to insufficient input validation of the 'deleteid' parameter, which allows an attacker to inject malicious SQL queries remotely.
This vulnerability can be exploited using various SQL injection techniques such as boolean-based blind, error-based, and time-based blind attacks.
How can this vulnerability impact me? :
The SQL injection vulnerability can lead to unauthorized access to the database, allowing attackers to tamper with data, leak sensitive information, and potentially gain full control over the affected system.
This poses a serious threat to system security and business continuity.
How can this vulnerability be detected on my network or system? Can you suggest some commands?
This vulnerability can be detected by testing the 'deleteid' parameter in the '/OnlineClassroom/studentdetails' endpoint for SQL injection flaws. Techniques include boolean-based blind, error-based, and time-based blind SQL injection tests.
Common commands to detect such SQL injection vulnerabilities include using tools like sqlmap or manual injection attempts with payloads that cause delays or errors. For example, using sqlmap:
- sqlmap -u "http://target/OnlineClassroom/studentdetails?deleteid=1" --batch --level=5 --risk=3
- Manually testing with payloads such as '1 OR 1=1--' or '1' AND SLEEP(5)--' in the deleteid parameter to observe abnormal responses or delays.
What immediate steps should I take to mitigate this vulnerability?
Immediate mitigation steps include implementing prepared statements to handle the 'deleteid' parameter safely and applying strict input validation to prevent malicious SQL code execution.
Additionally, minimize database permissions to limit the impact of a potential exploit and conduct regular security audits to identify and address similar vulnerabilities.
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 unauthorized database access, data tampering, and sensitive information leakage. Such impacts can lead to violations of data protection regulations like GDPR and HIPAA, which require safeguarding personal and sensitive data against unauthorized access and breaches.
Failure to address this vulnerability could result in non-compliance with these standards due to potential exposure of personal data, risking legal penalties and damage to business continuity.
