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. |

AI Powered Q&A
Can you explain this vulnerability to me?
This vulnerability is a SQL Injection found in Support Board version 3.7.7. It occurs through the 'calls[0][message_ids][]' parameter in the '/supportboard/include/ajax.php' endpoint. An attacker can exploit this flaw to manipulate the database by retrieving, creating, updating, or deleting data.
How can this vulnerability impact me? :
The impact of this vulnerability is significant because it allows an attacker to perform unauthorized actions on the database, including retrieving sensitive information, modifying existing data, or deleting data. This can lead to data breaches, loss of data integrity, and disruption of service.
How does this vulnerability affect compliance with common standards and regulations (like GDPR, HIPAA)?:
The SQL Injection vulnerability in Support Board v3.7.7 allows unauthorized access to retrieve, create, update, and delete database information, which can lead to exposure or manipulation of sensitive data.
Such unauthorized data access and manipulation can result in non-compliance with data protection regulations like GDPR and HIPAA, which require strict controls over the confidentiality, integrity, and availability of personal and sensitive information.
Therefore, exploitation of this vulnerability could lead to violations of these standards due to potential data breaches or unauthorized data alterations.
What immediate steps should I take to mitigate this vulnerability?
To mitigate the SQL Injection vulnerability in Support Board v3.7.7 and earlier, you should immediately upgrade to Support Board version 3.7.8 or later, where the issue has been fixed by the development team.
How can this vulnerability be detected on my network or system? Can you suggest some commands?
This vulnerability can be detected by monitoring and testing the '/supportboard/include/ajax.php' endpoint for SQL Injection attempts targeting the 'calls[0][message_ids][]' parameter.
A common approach is to use tools like curl or sqlmap to send crafted requests to this endpoint and observe if unauthorized database operations are possible.
- Example curl command to test for SQL Injection: curl -X POST 'http://target-site/supportboard/include/ajax.php' -d 'calls[0][message_ids][]=1' -v
- Using sqlmap to test the parameter: sqlmap -u 'http://target-site/supportboard/include/ajax.php' --data='calls[0][message_ids][]=1' --batch
Monitoring network traffic for unusual or suspicious POST requests to this endpoint with the specific parameter can also help detect exploitation attempts.
