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. |

Can you explain this vulnerability to me?
[{'type': 'paragraph', 'content': 'CVE-2026-3736 is a critical SQL injection vulnerability found in version 1.0 of the code-projects Simple Flight Ticket Booking System, specifically in the file SearchResultRoundtrip.php.'}, {'type': 'paragraph', 'content': "The vulnerability arises from improper handling of the 'from' argument, which is used to construct SQL commands without proper neutralization or sanitization of special characters, leading to the possibility of injecting malicious SQL code."}, {'type': 'paragraph', 'content': 'This flaw allows remote attackers to execute arbitrary SQL commands without requiring authentication, potentially compromising the confidentiality, integrity, and availability of the system.'}] [1, 2, 3]
How can this vulnerability impact me? :
Exploitation of this vulnerability can lead to unauthorized database access, allowing attackers to retrieve, modify, or delete sensitive data.
Attackers can perform data leakage, data tampering, gain full system control, and cause service interruptions.
No authentication is required to exploit this vulnerability, making it easier for remote attackers to compromise the system.
This poses a serious threat to system security and business continuity.
How does this vulnerability affect compliance with common standards and regulations (like GDPR, HIPAA)?:
I don't know
How can this vulnerability be detected on my network or system? Can you suggest some commands?
[{'type': 'paragraph', 'content': "This vulnerability can be detected by targeting the SearchResultRoundtrip.php endpoint and testing the 'from' POST parameter for SQL injection."}, {'type': 'paragraph', 'content': 'One method is to use Google dorking with the query: inurl:SearchResultRoundtrip.php to identify potentially vulnerable targets.'}, {'type': 'paragraph', 'content': 'Technical detection can be performed using SQL injection testing tools such as sqlmap, which can send crafted POST requests to the vulnerable parameter.'}, {'type': 'list_item', 'content': "Example boolean-based blind SQL injection payload: from=London') RLIKE (SELECT (CASE WHEN (9900=9900) THEN 0x4c6f6e646f6e ELSE 0x28 END)) AND ('Xmon'='Xmon"}, {'type': 'list_item', 'content': "Example time-based blind SQL injection payload: from=London') AND (SELECT 5183 FROM (SELECT(SLEEP(5)))CJAu) AND ('IwrL'='IwrL"}, {'type': 'paragraph', 'content': 'Using sqlmap, you can run a command similar to: sqlmap -u "http://target/SearchResultRoundtrip.php" --data="from=London" --method=POST to test for injection.'}] [1, 2]
What immediate steps should I take to mitigate this vulnerability?
[{'type': 'paragraph', 'content': 'Immediate mitigation steps include:'}, {'type': 'list_item', 'content': 'Use prepared statements with parameter binding to separate SQL code from user input, preventing SQL injection.'}, {'type': 'list_item', 'content': 'Implement strict input validation and filtering to ensure inputs conform to expected formats.'}, {'type': 'list_item', 'content': "Minimize database user permissions by avoiding the use of high-privilege accounts such as 'root' or 'admin' for application database connections."}, {'type': 'list_item', 'content': 'Conduct regular security audits of code and systems to detect and fix vulnerabilities promptly.'}, {'type': 'paragraph', 'content': 'If possible, replace the affected component with an alternative product as no known mitigations or countermeasures have been documented.'}] [1, 2, 3]
