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?
CVE-2019-25537 is a time-based blind SQL injection vulnerability in Netartmedia Event Portal 2.0. It occurs in the login functionality, specifically through the Email parameter in POST requests to loginaction.php. An attacker can inject malicious SQL code without authentication, causing the database to execute unintended queries. This allows the attacker to manipulate database queries and extract sensitive information by observing time delays in the database response.
How can this vulnerability impact me? :
This vulnerability can have a significant impact by allowing unauthenticated attackers to extract sensitive information from the backend database. Since the attack requires no privileges or user interaction, it poses a high risk to confidentiality. Attackers can manipulate database queries to access data they should not have, potentially leading to data breaches or exposure of private information.
How does this vulnerability affect compliance with common standards and regulations (like GDPR, HIPAA)?:

[{'type': 'paragraph', 'content': 'This vulnerability can be detected by sending a specially crafted POST request to the /loginaction.php endpoint with a time-based blind SQL injection payload in the Email parameter.'}, {'type': 'paragraph', 'content': "For example, the following payload can be used to test the vulnerability: '|| (SELECT 0x59685353 FROM DUAL WHERE 7114=7114 AND SLEEP(5)) ||'. If the server response is delayed by approximately 5 seconds, it confirms the presence of the vulnerability."}, {'type': 'paragraph', 'content': 'A sample curl command to test this would be:'}, {'type': 'list_item', 'content': 'curl -X POST -d "Email=\'|| (SELECT 0x59685353 FROM DUAL WHERE 7114=7114 AND SLEEP(5)) ||\'&Password=anyvalue" https://targetsite.com/loginaction.php -v'}, {'type': 'paragraph', 'content': 'Monitoring for unusual delays in response times to POST requests on the loginaction.php endpoint with suspicious Email parameter values can help detect exploitation attempts.'}] [1, 2]
What immediate steps should I take to mitigate this vulnerability?
Immediate mitigation steps include:
- Apply input validation and sanitization on the Email parameter to prevent SQL injection.
- Use prepared statements or parameterized queries in the loginaction.php script to safely handle user inputs.
- Restrict access to the loginaction.php endpoint if possible, or implement web application firewall (WAF) rules to detect and block SQL injection attempts.
- Monitor logs for suspicious POST requests targeting the Email parameter.
Additionally, check for any available patches or updates from the vendor and apply them as soon as possible.
