| 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-2026-2690 is a SQL injection vulnerability found in the itsourcecode Event Management System version 1.0, specifically in the Admin Login component within the file /admin/ajax.php?action=login.'}, {'type': 'paragraph', 'content': "The flaw occurs because the 'username' parameter is not properly sanitized or validated, allowing an attacker to inject malicious SQL code during the login process."}, {'type': 'paragraph', 'content': 'This vulnerability can be exploited remotely without authentication, enabling attackers to manipulate SQL queries and perform unauthorized database operations.'}] [1, 2, 3]
How can this vulnerability impact me? :
Exploitation of this SQL injection vulnerability can lead to unauthorized access to the database, allowing attackers to read, modify, or delete sensitive data.
Attackers can gain full system control, cause data tampering, leak sensitive information, and disrupt services, severely compromising system security and business continuity.
- Unauthorized database access
- Sensitive data leakage
- Data tampering
- Full system control
- Potential service disruption
How does this vulnerability affect compliance with common standards and regulations (like GDPR, HIPAA)?:

How can this vulnerability be detected on my network or system? Can you suggest some commands?
[{'type': 'paragraph', 'content': "This SQL injection vulnerability can be detected by testing the vulnerable endpoint /admin/ajax.php?action=login, specifically the 'username' parameter in POST requests, for injection flaws."}, {'type': 'paragraph', 'content': 'One can use tools like sqlmap to automate detection. An example command to test this vulnerability is:'}, {'type': 'list_item', 'content': 'python sqlmap.py --random-agent --batch -u "http://<target-ip>:<port>/admin/ajax.php?action=login" --data "username=admin&password=admin" --dbms=mysql --current-db'}, {'type': 'paragraph', 'content': "Additionally, manual testing can be done using boolean-based blind or time-based blind SQL injection payloads in the 'username' parameter, such as:"}, {'type': 'list_item', 'content': "Boolean-based blind payload: username=admin' AND 1192=1192 AND 'zUrD'='zUrD&password=admin"}, {'type': 'list_item', 'content': "Time-based blind payload (MySQL >= 5.0.12): username=admin' AND (SELECT 4775 FROM (SELECT(SLEEP(5)))tIKm) AND 'HBou'='HBou&password=admin"}] [3]
What immediate steps should I take to mitigate this vulnerability?
Immediate mitigation steps include:
- Implement prepared statements and parameter binding to separate SQL code from user input, preventing injection.
- Apply strict input validation and filtering to ensure inputs conform to expected formats.
- Minimize database user permissions by avoiding use of high-privilege accounts for routine operations.
- Conduct regular security audits to detect and address vulnerabilities promptly.
Due to the lack of known countermeasures and mitigations currently available, replacement of the affected product is suggested if possible.
