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-2019-25531 is an SQL injection vulnerability in the Netartmedia Deals Portal web application. It exists in the Email parameter of the loginaction.php script, which is vulnerable to injection via POST requests. Because the Email input is not properly sanitized, an attacker can inject malicious SQL code.
This vulnerability allows unauthenticated attackers to manipulate database queries by submitting crafted SQL payloads. For example, attackers can use time-based blind SQL injection techniques to infer database responses and extract sensitive information.
How can this vulnerability impact me? :
This vulnerability can have serious impacts including unauthorized access to sensitive data stored in the backend database of the Deals Portal application.
- Attackers can extract sensitive information by manipulating SQL queries.
- Attackers can bypass authentication mechanisms, potentially gaining unauthorized access to user accounts or administrative functions.
Because the attack requires no privileges or user interaction and can be performed remotely over the network, it poses a high risk to affected systems.
How does this vulnerability affect compliance with common standards and regulations (like GDPR, HIPAA)?:

How can this vulnerability be detected on my network or system? Can you suggest some commands?
[{'type': 'paragraph', 'content': 'This SQL injection vulnerability can be detected by sending crafted POST requests to the loginaction.php script targeting the Email parameter with SQL payloads and observing the responses or delays.'}, {'type': 'paragraph', 'content': 'A proof-of-concept command uses a time-based blind SQL injection payload to detect the vulnerability by causing a delay if the injection is successful.'}, {'type': 'paragraph', 'content': 'An example curl command to test this is:'}, {'type': 'list_item', 'content': 'curl -X POST -d "Email=0\'XOR(if(now()=sysdate(),sleep(0),0))XOR\'Z&Password=test&language=en" https://targetsite.com/loginaction.php'}, {'type': 'paragraph', 'content': 'If the server response is delayed or behaves differently, it indicates the presence of the SQL injection vulnerability.'}] [1]
What immediate steps should I take to mitigate this vulnerability?
Immediate mitigation steps include:
- Restrict or block access to the vulnerable loginaction.php script until a patch or fix is applied.
- Implement input validation and sanitization on the Email parameter to prevent SQL injection.
- Use prepared statements or parameterized queries in the backend code to avoid direct SQL query manipulation.
- Monitor logs for suspicious POST requests targeting the Email parameter.
