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-2026-1688 is a critical SQL injection vulnerability in the itsourcecode Directory Management System version 1.0, specifically in the /admin/index.php file. The vulnerability arises from improper handling and inadequate validation of the 'username' parameter, which allows attackers to inject malicious SQL code remotely without authentication. This injection can manipulate database queries, leading to unauthorized access, data leakage, data modification, and potentially full system compromise. [1, 2, 3]
How can this vulnerability impact me? :
This vulnerability can have severe impacts including unauthorized access to the database, leakage of sensitive data, unauthorized data modification or deletion, full system control by attackers, and potential disruption of services. Since exploitation requires no authentication and can be performed remotely, it poses a significant threat to system security and business continuity. [1, 2, 3]
How can this vulnerability be detected on my network or system? Can you suggest some commands?
This vulnerability can be detected by testing the /admin/index.php endpoint for SQL injection via the 'username' parameter in POST requests. A common method is to use sqlmap to automate detection. For example, you can run a command like: sqlmap -u "http://target/dms/admin/index.php" --data="username=admin&password=123456&login=login" --method=POST --level=5 --risk=3 --batch. Additionally, a time-based blind SQL injection payload such as username=admin' AND (SELECT 4296 FROM (SELECT(SLEEP(5)))kIKP) AND 'vXyy'='vXyy can be used to confirm the vulnerability by observing delayed responses. [1]
What immediate steps should I take to mitigate this vulnerability?
Immediate mitigation steps include: 1) Implement prepared statements with parameter binding to prevent SQL injection by separating SQL code from user input. 2) Apply strict input validation and filtering on the 'username' parameter to ensure it conforms to expected formats. 3) Limit database user permissions to the minimum necessary, avoiding use of high-privilege accounts such as 'root' or 'admin' for routine operations. 4) Conduct regular security audits of code and systems to detect and address vulnerabilities promptly. If possible, consider replacing the affected product with a secure alternative. [1, 2]
How does this vulnerability affect compliance with common standards and regulations (like GDPR, HIPAA)?:
The vulnerability allows unauthorized access, data leakage, and data manipulation due to SQL injection, which can lead to exposure and compromise of sensitive information. Such unauthorized data breaches and integrity violations can negatively impact compliance with common standards and regulations like GDPR and HIPAA, which require protection of personal and sensitive data. Therefore, exploitation of this vulnerability poses a risk to meeting these regulatory requirements. [1, 2, 3]
