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-2026-5640 is a critical SQL injection vulnerability found in the PHPGurukul Online Shopping Portal Project version 2.1, specifically in the /admin/update-image2.php file. The vulnerability occurs because the 'filename' parameter is not properly sanitized or validated before being used in SQL queries. This flaw allows attackers to inject malicious SQL code remotely, potentially gaining unauthorized access to the database, leaking sensitive data, tampering with data, or even compromising the entire system.
The vulnerability was demonstrated using a time-based blind SQL injection technique, where specially crafted input caused delays in SQL query execution, confirming the injection point. An example payload included a filename with embedded SQL commands that triggered a sleep delay, proving the vulnerability.
How can this vulnerability impact me? :
This vulnerability can have severe impacts including unauthorized database access, data leakage, and data tampering. Attackers can exploit the flaw to extract sensitive information, modify or delete data, and potentially execute arbitrary code on the server. This can lead to full system compromise, disrupting business operations and compromising system security and integrity.
- Unauthorized access to sensitive customer and business data.
- Data leakage and exposure of confidential information.
- Data tampering or deletion, affecting data integrity.
- Potential full system compromise through code injection.
- Disruption of business continuity and loss of customer trust.
How can this vulnerability be detected on my network or system? Can you suggest some commands?
This vulnerability can be detected by testing the 'filename' parameter in the /admin/update-image2.php file for SQL injection. A common method is to send specially crafted requests that cause a delay in the SQL query execution, indicating a time-based blind SQL injection.
For example, sending a multipart/form-data POST request to /shopping/admin/update-image2.php?id=2 with a 'productimage2' filename containing a payload like: `4de8a7b75cc40f55f9f021d6608b0d25.jpg' RLIKE SLEEP(5) AND 'piJt'='piJt` can confirm the vulnerability if the response is delayed.
Additionally, the sqlmap tool can be used to automate detection and exploitation of this SQL injection vulnerability.
- Use curl or similar tools to send the crafted POST request with the payload in the filename parameter.
- Run sqlmap against the vulnerable URL, for example: `sqlmap -u "http://target/shopping/admin/update-image2.php?id=2" --data="productimage2=4de8a7b75cc40f55f9f021d6608b0d25.jpg' RLIKE SLEEP(5) AND 'piJt'='piJt" --method=POST`
What immediate steps should I take to mitigate this vulnerability?
Immediate mitigation steps include:
- Employ prepared statements with parameter binding to separate SQL code from user input, preventing SQL injection.
- Implement rigorous input validation and filtering to ensure inputs conform to expected formats and block malicious data.
- Minimize database user permissions by avoiding the use of high-privilege accounts (such as root or admin) for routine operations.
How does this vulnerability affect compliance with common standards and regulations (like GDPR, HIPAA)?:
The SQL injection vulnerability in the PHPGurukul Online Shopping Portal Project 2.1 allows unauthorized database access, data leakage, and data tampering. Such security weaknesses can lead to breaches of sensitive personal or health information, which directly impacts compliance with regulations like GDPR and HIPAA that mandate protection of data confidentiality and integrity.
Failure to remediate this vulnerability could result in unauthorized disclosure or alteration of protected data, potentially causing violations of these standards and resulting in legal and financial penalties.
Therefore, addressing this vulnerability by implementing prepared statements, input validation, and minimizing database privileges is critical to maintaining compliance with common data protection regulations.
