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-2026-6188 is a critical SQL injection vulnerability found in the SourceCodester Pharmacy Sales and Inventory System 1.0, specifically in the file /ajax.php?action=delete_sales. The flaw occurs because the system improperly handles the 'id' parameter received via POST requests without adequate input validation or sanitization.
Attackers can exploit this vulnerability by injecting malicious SQL code through the 'id' parameter, which allows them to manipulate the SQL queries executed by the system. This can lead to unauthorized database access, data leakage, data tampering, deletion or modification of records, and potentially gaining full control over the system or causing service interruptions.
Importantly, exploitation does not require any authentication or authorization, making it easier for remote attackers to initiate the attack.
How can this vulnerability impact me? :
This vulnerability can have severe impacts including unauthorized access to sensitive data stored in the database, leakage of confidential information, unauthorized modification or deletion of records, and disruption of service availability.
Attackers may gain full control over the affected system, which can lead to further exploitation, data breaches, and loss of business continuity.
Since the attack can be performed remotely without authentication, the risk of exploitation is high.
How can this vulnerability be detected on my network or system? Can you suggest some commands?
The CVE-2026-6188 vulnerability can be detected by testing the /ajax.php?action=delete_sales endpoint for SQL injection via the id parameter, which is accepted through POST requests without proper validation.
One effective method is to use automated tools like sqlmap to confirm the presence of the injection point and enumerate databases.
A proof-of-concept payload example for testing is: id=(SELECT (CASE WHEN (4784=4784) THEN 5 ELSE (SELECT 7976 UNION SELECT 3350) END))
Using sqlmap, a command to test might look like: sqlmap -u "http://target/ajax.php?action=delete_sales" --data="id=1" --method=POST
What immediate steps should I take to mitigate this vulnerability?
Immediate mitigation steps include:
- Use prepared statements with parameter binding to separate SQL code from user input, preventing execution of injected SQL.
- Implement strict input validation and filtering to ensure parameters conform to expected formats.
- Minimize database user permissions by avoiding use of high-privilege accounts (e.g., root or admin) for routine database operations.
- Conduct regular security audits of code and systems to detect and address vulnerabilities promptly.
How does this vulnerability affect compliance with common standards and regulations (like GDPR, HIPAA)?:
The SQL injection vulnerability in the Pharmacy Sales and Inventory System allows unauthorized access, data leakage, and data tampering. Such unauthorized access and potential exposure or modification of sensitive data can lead to non-compliance with data protection regulations like GDPR and HIPAA, which require the protection of personal and health-related information.
Failure to secure the system against this vulnerability could result in breaches of confidentiality, integrity, and availability of data, which are core principles in these regulations. This may lead to legal penalties, loss of trust, and damage to the organization's reputation.
