Overview
CVE-2025-13575 is a medium-severity SQL injection vulnerability discovered in code-projects Blog Site version 1.0. The vulnerability resides within the Category Handler, specifically the category_exists function in the /resources/functions/blog.php file. Successful exploitation of this vulnerability allows remote attackers to inject malicious SQL code by manipulating the name/field argument.
Technical Details
The vulnerability stems from insufficient sanitization of user-supplied input within the category_exists function. An attacker can inject SQL commands through the name/field argument of the function, potentially allowing them to read, modify, or delete data in the database. This vulnerability can be exploited remotely without authentication, making it a significant threat. Multiple endpoints of the application are vulnerable, increasing the attack surface.
CVSS Analysis
The vulnerability has been assigned a CVSS score of 6.3 (MEDIUM). This score reflects the potential impact and exploitability of the vulnerability. While not critical, the ease of remote exploitation and the potential for data compromise necessitate prompt mitigation.
Possible Impact
Successful exploitation of this SQL injection vulnerability could have severe consequences, including:
- Data Breach: Attackers could gain unauthorized access to sensitive data stored in the database, such as user credentials, personal information, and blog content.
- Data Modification: Malicious actors could modify or delete data, leading to data corruption or loss.
- Account Takeover: By manipulating user data, attackers could potentially take over administrator or user accounts.
- Denial of Service (DoS): Attackers could inject SQL code that disrupts the application’s functionality, leading to a denial-of-service condition.
Mitigation and Patch Steps
To mitigate the risk posed by CVE-2025-13575, the following steps are recommended:
- Input Validation and Sanitization: Implement robust input validation and sanitization mechanisms for all user-supplied input, especially within the
category_existsfunction. Use parameterized queries or prepared statements to prevent SQL injection. - Web Application Firewall (WAF): Deploy a web application firewall to detect and block malicious SQL injection attempts.
- Update the Application: Check code-projects.org for official patches or updates for Blog Site 1.0. Apply the patch immediately to remediate the vulnerability. If no patch is available, consider other mitigation techniques.
- Least Privilege Principle: Ensure that the database user account used by the application has only the necessary privileges to perform its functions. This limits the impact of a successful SQL injection attack.
