| CWE ID | Description |
|---|---|
| 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. |
| 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. |

AI Powered Q&A
Can you explain this vulnerability to me?
CVE-2025-6844 is a critical SQL injection vulnerability in Simple Forum version 1.0, specifically in the /signin.php file. It occurs because the 'user' parameter is not properly validated or sanitized, allowing attackers to inject malicious SQL code. This flaw enables unauthorized access to the database, potentially allowing attackers to view, modify, or delete sensitive data. The attack can be performed remotely without authentication. [1, 2, 3]
How can this vulnerability impact me? :
Exploitation of this vulnerability can lead to unauthorized database access, data leakage, data tampering, and potentially full system control. It threatens the confidentiality, integrity, and availability of the system. Attackers can disrupt services, manipulate or delete data, and compromise 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 /signin.php endpoint for SQL injection on the 'user' parameter. A proof-of-concept uses a time-based blind SQL injection payload such as: user=harry' AND (SELECT 9069 FROM (SELECT(SLEEP(5)))KAuP) AND 'vsxl'='vsxl&password=pass which causes a delay in the database response. Additionally, the sqlmap tool can be used to automate detection with a command like: python sqlmap.py -u "http://localhost/cve/SimpleForum_PHP/bforum/signin.php" --data "user=harry&password=pass" --current-db --batch. Vulnerable targets can also be identified using Google dorking with queries like inurl:signin.php. [2, 3]
What immediate steps should I take to mitigate this vulnerability?
Immediate mitigation steps include: 1) Replace the affected software with an alternative product if possible. 2) Implement prepared statements with parameter binding to separate SQL code from user input, preventing injection. 3) Apply strict input validation and filtering to ensure user data conforms to expected formats. 4) Limit database user permissions to the minimum necessary, avoiding use of high-privilege accounts like 'root' or 'admin' for routine operations. 5) Conduct regular security audits of code and systems to detect and address vulnerabilities promptly.
