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
How can this vulnerability be detected on my network or system? Can you suggest some commands?
This vulnerability can be detected by monitoring for suspicious POST requests to the 'loginstart.asp' endpoint containing SQL injection payloads in the 'id' parameter. For example, sending crafted POST requests with payloads such as `id=' or 1=1--` can test for the vulnerability. Network intrusion detection systems (NIDS) can be configured to alert on such SQL injection patterns targeting the 'loginstart.asp' script. Additionally, manual testing using tools like curl or Burp Suite to send POST requests with malicious 'id' values can help detect the vulnerability. [2, 3, 4]
What immediate steps should I take to mitigate this vulnerability?
Immediate mitigation steps include restricting access to the vulnerable 'loginstart.asp' endpoint, applying input validation and sanitization on the 'id' parameter to prevent SQL injection, and updating or patching the COMMAX Smart Home System CDP-1020n firmware or software if a fix is available. If patches are not yet available, consider implementing network-level protections such as web application firewalls (WAF) to block malicious SQL injection attempts. Monitoring logs for suspicious activity and changing any potentially compromised credentials is also recommended. [2, 4]
Can you explain this vulnerability to me?
This vulnerability is an SQL injection in the COMMAX Smart Home System CDP-1020n. It allows attackers to bypass authentication by injecting malicious SQL code through the 'id' parameter in the 'loginstart.asp' page. By sending a specially crafted POST request with malicious 'id' values, attackers can manipulate database queries to gain unauthorized access.
How can this vulnerability impact me? :
The vulnerability can allow attackers to bypass authentication and gain unauthorized access to the COMMAX Smart Home System. This unauthorized access could lead to control over smart home devices, exposure of sensitive information, and potential further exploitation of the system.
