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-2026-5256 is a critical SQL injection vulnerability found in version 1.0 of the Simple Laundry System, specifically in the /modify.php file. The issue arises because the firstName parameter is not properly validated or sanitized before being used in SQL queries. This allows attackers to inject malicious SQL code remotely without needing authentication.
The vulnerability enables attackers to manipulate database queries, potentially extracting sensitive data, modifying or deleting records, or even taking full control of the system. Various SQL injection techniques such as Boolean-based blind, error-based, and time-based blind injections have been demonstrated against this parameter.
How can this vulnerability impact me? :
This vulnerability can have severe impacts including unauthorized access to the database, data leakage, data modification or deletion, and disruption of services. Attackers can exploit it remotely without authentication, which increases the risk of compromise.
- Unauthorized extraction of sensitive data.
- Modification or deletion of database records.
- Potential full system compromise or control.
- Disruption of business continuity and system security.
How can this vulnerability be detected on my network or system? Can you suggest some commands?
The vulnerability can be detected by testing the /modify.php endpoint of the Simple Laundry System 1.0 for SQL injection via the firstName parameter. This can be done by sending specially crafted payloads to observe if the system is vulnerable to SQL injection techniques such as Boolean-based blind, error-based, or time-based injections.
- Use curl or similar tools to send payloads to the firstName parameter and observe responses.
- Example command to test Boolean-based blind SQL injection using curl:
- curl -X POST -d "firstName=' OR 1=1 -- " http://target/modify.php
- Example command to test time-based blind SQL injection:
- curl -X POST -d "firstName=' OR IF(SLEEP(5),1,0) -- " http://target/modify.php
Monitoring network traffic for unusual SQL query patterns or unexpected database errors in responses can also help detect exploitation attempts.
What immediate steps should I take to mitigate this vulnerability?
Immediate mitigation steps include:
- Implement prepared statements for all database queries involving user inputs, especially the firstName parameter in /modify.php.
- Apply strict input validation and filtering to ensure that user inputs conform to expected formats and reject malicious payloads.
- Limit database user permissions to the minimum necessary, avoiding use of high-privilege accounts such as root or admin for routine operations.
- Conduct a thorough security audit of the codebase and system to identify and remediate similar vulnerabilities.
These steps will help protect data integrity and system security from exploitation of this SQL injection vulnerability.
How does this vulnerability affect compliance with common standards and regulations (like GDPR, HIPAA)?:
The SQL injection vulnerability in Simple Laundry System 1.0 allows attackers to gain unauthorized access to the database, potentially extracting, modifying, or deleting sensitive data. Such unauthorized data access and manipulation can lead to violations of data protection regulations like GDPR and HIPAA, which require strict controls to protect personal and sensitive information.
Failure to prevent this vulnerability could result in non-compliance with these standards due to inadequate protection of data confidentiality, integrity, and availability, potentially leading to legal and financial consequences.
